GECAD (Knowledge Engineering and Decision Support Research Centre) unit n. 760 of FCT (Portuguese Science & Technology Foundation) settled at ISEP/IPP (Institute of Engineering – Polytechnic of Porto)
GECAD Report
[2003-2007]
Message from the GECAD Director
Welcome to GECAD, the Knowledge
Engineering and Decision Support Research
Centre, settled at the Institute of Engineering
– Polytechnic of Porto (ISEP/IPP).
In 2003, when we were ranked with VERY GOOD level by the
Portuguese Science and Technology Foundation (FCT), we decided to
start a challenging trajectory that we called “the search for Excellence”.
In 2003, we had just 11 researchers with the PhD degree. We understood
that the main effort should be done in the increasing of the number of
PhD researchers. Now, we have 37 PhD researchers, and during the first
semester of 2008 we will have more than 45. Four times more, in 5
years! Certainly, one of the most impressive evolutions in the
Portuguese R&D system.
But this evolution has been achieved in a sustainable way. During the
period [2003-2007] GECAD was involved in more than 30 R&D
projects with external funding. We are one of the Portuguese R&D units
with more success at this level. Just a number, 9, is the number of
projects assigned to GECAD in the last FCT Call for Projects.
Many connections have been established with national and
international companies. However, GECAD wants to be proactive at
this level. In 2006 we started a new phase, with the creation of our first
spin-off, FlyMaster Avionics SA. With completely innovative products,
FlyMaster NAV+ and F1, this company created a free-flight on-board
pilot Assistant (e.g. gliding, hangliding, paragliding), with access to GPS
and sensorial information. FlyMaster Avionics S.A. is commercializing
these patented products, used by many pilots, including the Portuguese
and French paragliding national teams. FlyMaster products are today
considered as a clear advantage for free-flight competition pilots. These
products received the prestigious ANIMEE prize for Innovation and
Creativity. After this success, new spin-offs are now being planned.
The connection with the academic community is another strenght. At
the international level, GECAD is involved in the Collaboration
Agreement between the Portuguese Government and some
international institutions. Carnegie-Mellon University in the USA,
Fraunhofer Gesellshaft in Germany, and Imperial College in the UK (at
tentative phase) are three of the institutions referring GECAD in the
agreements. The creation of the Portuguese Chapter of the IEEE
Computational Intelligence Society with all 3 members of the Direction
from GECAD is another interesting aspect.
During the [2003-2007] period, all developed work has been achieved
with an international recognition. More than 400 publications have
been done, more than 70 in journals and magazines, many of them
with high impact factors. The invitation to some of our researchers to
act as guest editors of 18 special issues in important journals and
magazines shows the relevance of GECAD research at top level.
GECAD is also aware of its responsibility in the science and technology
divulgation for the young generations. In 2006, a tremendous success
was obtained in our celebrations of the 50th Artificial Intelligence
Anniversary. The AI-50 Exhibition was opened in the Parada Leitão
Museum from May to December 2006. This exhibition was seen by
dozens of thousands of visitors and received the attention of the
Portuguese TV and newspapers. The success was not reduced to the
Portuguese frontiers, a 3-page article was published in the July/August
2006 issue of the IEEE Intelligent Systems Magazine and a reference to
the exhibition was placed in the AAAI “AI Topics” web site.
GECAD established the cooperation with CENTRIA (Artificial
Intelligence Centre of the New University of Lisbon) to create the
backbone of the AI Associated Laboratory proposal COGNOMA
(Cognition in Man and Machine).
It is amazing to notice that with all these results, GECAD is settled in a
Polytechnic School. In 430 Portuguese R&D units just 8 are in this system.
GECAD is clearly considered the only R&D unit from the Polytechnic
system combining quality and critical mass. FCT recognizes this when
assigned to GECAD 3 positions to hire Post-Doc researchers during 5
years (75% of the total assigned to the entire Polytechnic system in
Portugal).
GECAD has 4 groups (research lines): Ambient Intelligence & Decision
Support; Computational Intelligence; Knowledge & Learning
Technologies; and Intelligent Energy Systems. The collaboration
between these 4 groups has been fantastic. In different ways, these
groups are in the state of the art at the international level.
I hope this report will show you some of our work at GECAD and open
the doors for new collaborations between your interests and ours. Let us
search for Excellence together!

Director of GECAD

COGNOMA Associated Laboratory Proposal
In Portuguese Science and Technology systems Associated Laboratories
represent the possibility to join high level research units for a focused
research activity in a certain area. GECAD and CENTRIA (Centre of
Artificial Intelligence of the New University of Lisbon) have joined
efforts for the proposal of creation of the Portuguese Associated
Laboratory dedicated to Artificial Intelligence, COGNOMA (Cognition
in Man and Machine). The proposal was made in July 2006, the year of
the 50th AI Anniversary.
The Associate Laboratory COGNOMA, with a broad scope in the global
area of “Cognition in Humans and Machines”, has as its main mission to
cooperate in a continuous, capable and efficient manner, in pursuing
specific objectives of the national scientific and technological policy,
namely in the areas of
• Ambient Intelligence and Embedded Systems
• Bio-Informatics
• Management of Critical Resources (including Energy and
Transports)
• Computational Processing of Natural Language
• Knowledge Based, Cognitive and Learning Systems
• Intelligent Planning and Systems
• Semantic Web
intertwining the competence and know-how accumulated in the
COGNOMA centres, stimulating the integration of research, scientific
education as well as the transfer of knowledge and technology to non
academic sectors, and contributing to the associated small and medium
companies.
-Introduction- 28
COGNOMA will be the Artificial Intelligence (AI) Laboratory of
reference in Portugal, ensuring its presence in the frontier of the most
advanced software applications. The Laboratory brings together the
largest AI university centre and the best polytechnic research centre, as
well as selected researchers from other institutions. It applies knowledge,
skills and experiences recognised world wide in the basic AI technologies,
reflecting in its original DNA, areas of critical application of intelligent
software for the next decade, from biotechnology to energy, among
many others.
The present COGNOMA proposal is well in line with the strategic goals,
both National and European, for Research and Development. The
main objective aimed at in the 7th Framework Programme of the
European Union is the fulfilment of the Lisbon strategy, i.e. to transform
the European Union in the most competitive Knowledge Based
Economy in the world. Such ambitious goal is not achievable without a
clear involvement of the Knowledge Technologies, that are at the core
of the COGNOMA contributions towards the national and European
development.
Moreover, the European Union assumes that the Information and
Communication Technologies are a priority area, assigning to them, for
the 2007 – 2013, the largest budget among the ten or so priority areas
selected at a European level. In the ICT area, 6 Technological Pillars
were defined: Nanotechnologies; Ubiquitous Communication Networks;
Embedded Systems; Software, Grids, security and dependability;
Knowledge, Cognitive and Learning Systems; Simulation, Visualization,
Interaction and Mixed Realities.
Notice that COGNOMA will centre its attention on this grand pillar of
Knowledge, Cognitive and Learning Systems, including the
Computational Processing of Written Portuguese. Additionally,
-Introduction- 29
COGNOMA will develop important activity within other related pillars,
such as the thematic areas of Ambient Intelligence (and respective
Embedded Systems), Bio-Informatics, Management of Critical Resources,
Intelligent Planning Systems (and their control), and the Semantic Web.
It should be stressed that these thematic areas will not only contribute
towards the priority area of Information and Communication
Technologies, but also towards other areas rated as strategic by the EU,
such as Energy, Transports and Security.
The text concerning the Knowledge and Cognitive and Learning
Systems, authored by the European Union (Dossier 2005/0185 - CNS)
predicts the development of methods and techniques to acquire, create
and interpret, represent and personalise, navigate and retrieve, share
and deliver knowledge, recognizing the semantic relationships, in
content for use by both humans and machines. It also predicts the
development of artificial systems that perceive, interpret and evaluate
information, and that can cooperate, act autonomously and learn.
These texts also refer the need for the development of theories and
experiences that move beyond mere incremental advances, benefiting
from insights into natural cognition, in particular in the areas of learning
and memory, also for the purpose of advancing systems for human
learning.
COGNOMA is aware of the environments for which the European Union
assigns top priorities, namely Personal Ambiences; Domestic Ambiences;
Robotic Systems; and Intelligent Infrastructures.

Introduction to Ambient Intelligence & Decision Support (AI&DS) group Decision Support Systems are interactive, flexible and adaptable
systems, especially developed to support non-structured problem
solving in order to improve decision making capabilities. Since 1993,
GECAD researchers have a long experience on the development of
Decision Support Systems.
Ambient Intelligent (AmI) deals with a new world where computing
devices are spread everywhere, allowing the human being to interact in
physical world environments in an intelligent and unobtrusive way.
These environments should be aware of the needs of people,
customizing requirements and forecasting behaviours. AmI has been
identified as one of the priority research areas in Europe on the last
years.
However, there is a trend to emphasize some operational and
infrastructural technologies in AmI, like sensing and communications,
and forget the most high level and strategic technologies, like those
related with Artificial Intelligence.
Ambient Intelligence & Decision Support group claims that decision
support features are essential in AmI environments.
This group wants to illustrate some decision support capabilities in AmI
environments, namely in the following situations:
- working environments (e.g. group meetings)
- leisure environments (e.g. tourist assistance, cultural heritage,
exhibitions)
- sports (e.g. free-flight assistants, cycling)
-AI&DS- 36
- manufacturing (e.g. production scheduling)
- transports (e.g. urban transports)
- energy (e.g. power systems control centres)
- home
Ambient Intelligent & Decision Support group has obtained a
meaningful scientific recognition during the last years.
This recognition is clear from the invitation made by James Hendler,
editor-in-chief of the IEEE Intelligent Systems magazine, to Carlos
Ramos in order to coordinate the Special Issue on Ambient Intelligence,
to appear in March/April 2008 issue.
Results are already passing from prototype to real world. FlyMaster
Avionics S.A. is a spin-off generated from this group. This spin-off
developed FlyMaster NAV+, a free-flight on-board pilot Assistant (e.g.
gliding, hangliding, paragliding), using the FlyMaster F1 module with
access to GPS and sensorial information. FlyMaster Avionics S.A. is
commercializing these patented products. These products constitute a
decision support system for the pilot and are being used by the
Portuguese and French paragliding national teams with fantastic
results.
GECAD was identified by Fraunhofer Gesellshaft as one of the 12
research centres with significant competence in the areas of the new
Fraunhofer Institute to be installed in Portugal, this institute will be
dedicated to Ambient Assisted Living.
One of the most important activities involving Ambient Intelligence was
the Exhibition “Artificial Intelligence – 50 Years”. The exhibition opened
on May 31, 2006 at the Parada Leitão Museum and was visited by
-AI&DS- 37
dozens of thousands of persons, received tremendous attention from the
media, international organizations, like AAAI, and magazines (IEEE
Intelligent Systems).
Another important result was the creation of LAID (Ambient
Intelligence for Decision Support Lab.), a kind of Intelligent Meeting
Room for Group Decision Support.
During [2003-2006] this group had 5 projects (PLANET-II, IMAGE,
SCALINTEL, ArgEmotionAgents, and PFA FLYMASTER) and 3 new
projects started in 2007 (PSiS, TOURSPLAN, and SmartVision).
This group envisages being an international reference in the application
of decision support in AmI environments. Publication of papers in good
scientific journals and conferences, edition of special issues, organization
of events are also envisaged. Following the GECAD culture, research
projects are an important goal to be considered by the group. The
creation of new spin-offs is also desired.

SCALINTEL - POCTI/EME/37525/2001 - Decision Support System for Scheduling with Scalable Intelligence
Project Leader: Carlos Ramos
email: [email protected]
SCALINTEL (Decision Support System for Scheduling with Scalable Intelligence) was a project supported by FCT that started in January/2002 with the duration of 3 years. It was started due to several studies that pointed out to some constraints in Decision Support Systems (DSS) for Scheduling. The first constraint was the difficulty in an intelligent interaction between the user and the DSS. DSS were not able to explain their reasoning or proposed solutions, like an Expert System, since this is very difficult for most of the scheduling algorithms. The second limitation was that DSS should not restrict to follow the user-interaction paradigm – they should infer what their users are trying to do and learn from the observation. Finally, decision-making is usually a process involving many people, advising for different aspects of the problem, which points for the need of Group DSS (GDSS). SCALINTEL contributed with the following originalities: new versions of scheduling algorithms oriented for intelligent interaction; use of case-based learning methods for user intention recognition; and use of Multi-Agent Systems paradigm for modelling GDSS.

ArgEmotionAgents - POSI/EIA/56259/2004 - Argumentative Agents with Emotional Behaviour Modelling for Participants’ Support in Group Decision-Making Meetings
Project Leader: Carlos Ramos
Email: [email protected]
ArgEmotionAgents is a project envisaging the use of Multi-Agent Systems approach for supporting Group Decision-Making processes, where Argumentation and Emotion components are especially important. Lots of work has been done in the Negotiation domain. Most of this work considers two participants negotiation, and involves rational decision making. ArgEmotionAgents intends to give a meaningful contribution. The work will be centered in Argumetation processes. These processes are so rich, namely because they do not consider just the rational aspects. An important emotional component is always present, such as gratitude debts, sympathy and friendship/hate relations between participants. Incompleteness, Quality of Information and Temporal Reasoning will be considered. Group Decision-Making was chose because in this domain argumentation has a crucial role, and because a significant number of participants, with different points of view, are usually involved. The final product of ArgEmotionAgents is the development of a Group Argumentation Support System, in which a community of agents will model the participants of a decision group, considering several proposals. With this platform it will be possible to give support to one or more group participants, suggesting the most convenient and adequate arguments, taking into account their objectives, the feasible proposals, voting trends and the profile of other participants. This project involves GECAD and the University of Minho.

PFA FlyMaster - Personal Flight Assistant project
Project Leader: Nuno Gomes
Email: [email protected]
Free flight sports, like gliding, hangliding and especially paragliding, are increasing every year. Up to now free flight pilots received few support from flight equipments, basically numeric GPS information. This drawback led to the development of FlyMaster project, creating a product that received innovation prizes and originated the FlyMaster Avionics SA spin-off. The main idea in the FlyMaster project is to create an on-board Ambient Intelligent environment composed by low-cost equipments able to assist pilots during the flight, giving them on-line decision support. FlyMaster products are now a great success in the free flight sports area, being a strong help, even for free-flight competition pilots. A significant amount of intelligence was integrated in FlyMaster products, namely to allow: the decision about when a pilot should move to the start line; the pilot support when climbing in the rising air columns (thermal lift); the trajectory plan; the glide optimization; and the context awareness to allow the automatic identification of the information to display since in this kind of sports both hands are necessary to control the gliding device. In this paper we will describe how FlyMaster is using these characteristics to allow a real pilot assistance and decision support on the fly. This project involves GECAD, Imediata, and Visteon Technologies.

PSiS - PTDC/TRA/72152/2006 - Personalized Sightseeing Planning System
Project Leader: Ana Almeida
Email: [email protected]
In this project we propose the development of a Personalised Sightseeing Planning System (PSiS) which intends to help tourists in finding a personalized tour plan allowing them to use their time efficiently and promote the culture and national tourism. Hence, this research focuses on tour planning support, we aim at defining and adapt a visit plan combining, in a tour, the most adequate tourism products, namely interesting places to visit, attractions, restaurants and accommodation, according to tourist’s specific profile (which includes interests, personal values, wishes, constraints and disabilities) and available transportation modes between the selected products. Functioning schedules will be considered as well as transportation schedules. In order to develop such a system we need to efficiently address the core of the tour planning process. Hence, we have to define an optimization model that clearly represents the described tour planning problem and design a heuristic algorithm that effectively tackles that problem. The Travelling Salesman Problem (TSP) and some of its variations with additional constraints like time windows (TSPTW) or the Prize Collecting Travelling Salesman Problem (PCTSP) have been used as basis for the development of algorithms that address tour planning issues. The TSP has been extensively studied by some of the members of this research. Following our TSP research, we intend to explore the application to the tour planning problem of advanced concepts and methods for the construction of effective neighborhood structures such as those derived from ejection chain methods and take advantage of the emerging methodologies, especially those that exploit the concept of adaptive memory programming.

TOURSPLAN - PTDC/EIA/74310/2006 - TOURS PLANning Support system
Project Leader: Ana Almeida
Email: [email protected]
When a tourist arrives to a new place (country, city or region) he would certainly appreciate to have a quite simple tool to assist him in planning his staying, according to his objectives, preferences, knowledge, budget and staying period, instead of having to look for guide prospects/bulletins which sometimes can be quite confuse, or having to follow a standardized plan which does not fulfil his needs. The tour planning task can be quite complex and time consuming due to the numerous attractions to visit, restaurants to eat and hotels available, when combining this task with the selection of transportation modes to move between selected places the complexity level raises, which is generally a discouraging factor for a tourist when trying to establish a plan that fulfils his needs, including preferences, wishes and constraints. Generated tour plans will be added to a “tour basket”, here the tourist has the possibility of eliminate selected attractions or add new ones, according his actual interest, motivation or availability. The system gathers knowledge about the tourist’s profiles, creating groups and stereotypes with specific interests and features, allowing characteristics inheritance. The “tour basket” stores tourist’s travel history, where all the places he visited are stored, which leads to accumulated knowledge about personal profiles. This knowledge, together with tourist stereotypes offer a mean of learning about general and specific interests of tourists, so that this information can serve as a basis for studying new forms of tourist products, which can be useful for the tourism sector, namely public entities (e.g. city council) as well as for travel agencies. It will be possible to return information on accomplished tours. So, the system gathers knowledge about tourist’s opinions and preferences. Based on this knowledge and on profile groups categorised information can be delivered according to tourist specific interests, namely events, factual information, useful tips, promotional offers, recommended places to visit and more. This project involves GECAD and CENTRIA (New University of Lisbon).

SmartVision - PTDC/EIA/73633/2006 - Active vision for the blind
Project Coordinator at GECAD: João Barroso
Email: [email protected]
Vehicles can be equipped with a GPS/GIS-based navigation system. By contrast, blind and visually impaired persons need to navigate using the stick or, at best, an ultrasonic obstacle detector. This asymmetry needs to be solved, an estimated 180 million persons with severe impairments of which 40-50 million are completely blind, and every year 2 million people more become blind. The Greek project SmartEyes aims at developing a portable GPS/GIS-based navigation aid for the blind, obviously limited to outdoor navigation and stable landmarks like zebra crossings, bus stops, shops etc. This FCT project concerns a collaboration with the SmartEyes project, for developing an active vision module. We will develop the necessary technology for outdoor and indoor navigation, with obstacle avoidance and object recognition. Main problems to be solved are the detection of outlines of sidewalks and zebra crossings while walking, including nearby obstacles like trees, traffic signs, persons (children) and dogs. Indoor navigation requires detection of corridors, doors and furniture, but also locating objects, like a ketchup bottle in a pantry or fridge. Only by complementing SmartEyes with realtime vision it will become a really smart aid! The necessary hardware is already available: a palmtop with BlueTooth link and GPS (in the future Galileo), plus cameras with USB interface. The main problem of a palmtop is its processor without floating-point units, which means that state-of-the-art algorithms from computer vision must be implemented using integers. There are two solutions: (a) most of the processing can be done remotely on a normal PC or even a small cluster, and (b) instead of applying most processing from the first to the last pixel of the video frames, processing can be limited to important regions by using a model of human vision, namely Focus-of-Attention (FoA). Instead of only focusing on computer vision, this project establishes a link with human vision. Recent progress in the modelling of processes in the visual cortex showed that computational models can already compete with the state-of-the-art in computer vision. This concerns 2D multi-scale line/edge and keypoint extraction, Focus-of-Attention and object categorisation. Linking computer vision and human vision allows to "combine the best of two worlds". For example, recognition of rotated 3D objects by using a limited number of views in visual memory is a difficult problem to be solved because of outliers, but robust methods are available from computer vision. This project involves GECAD/UTAD, University of Algarve, AIBILI, and IST.

Introduction to Computational Intelligence (CI) group Computational Intelligence corresponds to a set of techniques used to
build Intelligent Systems by combining basic elements of learning,
adaptation, and evolution. Referred sometimes as Soft Computing
and/or Metaheuristics, Computational Intelligence involves many
different techniques like Genetic Algorithms, Tabu Search, Simulated
Annealing, Neural Networks, Swarm Intelligence, Ant Colonies, Fuzzy
Systems, Chaos Theory, Fractals, Artificial Immune systems, Wavelets,
and more recently Fractional Calculus.
The use of Fractional Calculus in the modelling of complex nonlinear
system is emerging as a new promising area. The Computational
Intelligence group of GECAD constitute an international reference in
this field, namely by the work developed by José Tenreiro Machado,
who is frequently requested to present Plenary Sessions and to edit
Special Issues of Journals about this topic. Notice that Fractional
Calculus is still in a fundamental research phase.
The combination of Multi-Agent Systems with some of the
Computational Intelligence techniques, namely with Genetic Algorithms
and Tabu Search, is another area where the Computational Intelligence
group is involved.
The main goal of the Computational Intelligence group is to be an
international reference in some specific topics of Computational
Intelligence and the involvement in international forums, working
groups, and organizations chapters of the related.
-CI- 60
Publication of papers in good scientific journals and conferences, edition
of special issues, organization of events is also envisaged. Due to the
more fundamental orient research of some important topics of the
group the attention should be more centred in the scientific evolution of
the field.
Application domains of the developed techniques are so diverse
involving Robotics, Manufacturing, Energy, Transports, Music, etc.
Fractional Calculus is an area where this group is obtaining an
extraordinary recognition. Besides more than 20 publications in
scientific journals, other scientific results have been achieved in
Computational Intelligence, namely:
- the edition or acceptance for future edition of 15 special issues for
scientific journals;
- the edition of 7 complete books (4 from Springer and 3 from Ubooks).
The 15 special issues of journals are the following:
-Signal Processing, Elsevier, “Fractional Signal Processing and
Applications”, 83(11), 2003

Fractional SC - Integration of Green Functions as Fractional Order Derivatives in Non-linear Systems’ Control Based on a Novel Branch of Soft Computing
Project Coordinator at GECAD: José Tenreiro Machado
email: [email protected]
The project “Fractional SC - Integration of Green Functions as Fractional Order Derivatives in Non-linear Systems’ Control Based on a Novel Branch of Soft Computing” envisages considering Soft Computing techniques in Non-Linear Systems with Fractional Order Derivatives. On the basis of the idea of neural networks (cropping up in the forties) and the fuzzy sets (appearing in the sixties) new modelling possibilities became available. Typical problem classes have been identified for modelling of which typical uniform architectures containing a plenty of free parameters were available. By tuning these parameters either in a quie causal (e.g. by gradient descent, simplex or complex algorithm), quite stochastic (e.g. by genetic algorithms) or combined (e.g. simulated annealing) manner uniform machine learning methods has been introduced. These are independent of the particular details of the given problem to be solved by them. The combination of these three basic components is referred to as "Soft Computing, (SC)". Their application is especially advantageous whenever the analytical system model is too complex, requires huge computational burden, or it is impossible to identify its parameters or such identification needs too much calculations. This project started in 2004 and José Tenreiro Machado is the responsible for the Portuguese group, while Prof. József Kázmér Tar is responsible for the Hungarian group (Budapest Polytechnic).

MASDScheGATS - POCTI/EME/61229/2004 - Multi-Agent System for Distributed Manufacturing Scheduling with Genetic Algoritms and Tabu Search
Project Leader: Ana Madureira
email: [email protected]
In MASDScheGATS Project we model a Manufacturing Systems by means of a Multi-Agent Systems, where each agent may represent a processing entity (e.g. a machine). The project has as objective to deal with the complex problem of Dynamic Scheduling in Manufacturing Systems. A good global solution for a scheduling problem may emerge from a community of machine agents solving locally their schedules and cooperating with other machine agents that shares some relations between the operations/jobs (e.g. a precedence relation). Genetic Algorithms and Tabu Search methods can be adapted to deal with dynamic problems, reusing and changing solutions/populations in accordance with the dynamism of the Manufacturing System. The self-parameterisation of the Genetic Algorithms and Tabu Search methods allow a better adaptation to the situation being considered.
-CI- 71
AutoDynAgents - PTDC/EME-GIN/66848/2006 - Autonomic Agents with Self-Managing Capabilities for Dynamic Scheduling Support in a Cooperative Manufacturing System
Project Leader: Ana Madureira
email: [email protected]
AutoDynAgents is a project envisaging the use of Multi-Agent Systems paradigm for supporting dynamic and distributed scheduling in Manufacturing Systems with Autonomic properties, in order to reduce the complexity of managing systems and human interference. The objective of AutoDynAgents is to define a Multi-Agent Autonomic and Bio-Inspired based framework with learning and self-managing capabilities to solve complex scheduling problems using cooperative negotiation. The scheduling system will be equipped with some degree of problem diagnosis and resolution capability, incorporating the concept of Autonomic Computing, by self-configuration, self-optimization and self-healing. The final product of AutoDynAgents is an Autonomic Scheduling System in which a community of agents model a real manufacturing system subject to perturbations. Agents must be able to learn and manage their internal behaviour and their relationships with other autonomic agents, by cooperative negotiation in accordance with business policies defined by user manager. Cooperative Negotiation is quite important at this approach; we consider a Multi-dimensional Negotiation process depending upon the effort that the agents want to expend based on business. This project involves GECAD and CENTRIA (New University of Lisbon).

Research Group on Intelligent Energy Systems
(IES)
-IES- 84
-IES- 85
Introduction to Intelligent Energy Systems (IES) group Intelligent Energy Systems (IES) have as a goal to use all kind of energy
resources in an intelligent way. This includes a wide set of activity sectors
(generation, transmission, distribution and utilization) and involved
players. Issues addressed in this context include concepts as renewable
sources, energy efficiency and management but also intelligent
operation in all energy related activities, adequately supported by
decision-support systems, based on the required technologies. In fact, IES
are currently related with intelligent behaviour and adequate
management methods but, most of the times, the required technologies
to support this behaviour are not adequately addressed.
This group aims at addressing this topic, having as a basis the need to
use Artificial Intelligence (AI) concepts and methodologies to achieve
the goal of IES. The main objective of the IES group is to develop and
concentrate critical scientific and technological mass around the IES
concept, contributing to obtaining further developments in the
intelligent use of energy, by means of the use of adequate
methodologies, namely those based on AI. Although this group considers
energy activities as a whole, it is mainly focussed on electrical
engineering and power systems.
The main areas where this group works are:
- Power system operation
- Competitive Electricity market modelling and operation, including
both technical and economic issues
- Renewable sources based electricity generation and Distributed
Generation.
-IES- 86
IES group has obtained significant scientific recognition during the last
years. This recognition is justified by several factors, such as: the quality
of the main publications, the support of proposed research projects,
decided by international experts, the invitation to participate in
international associations’ activities, the revision of papers for top-
quality journals.
R&D Projects under the scope of IES group include 6 projects (DAMICE,
ISEPMain, IDDA, APRICOT, Agents&Markets, FENDIN) during [2003-
2006] and 2 new projects starting in 2007 (RiMaCEM and ViP-DiGEM).
IES is participating in several international working groups, namely the
following under the scope of IEEE Power Engineering Society: Intelligent
Systems Subcommittee, Working group on Intelligent Data Mining, and
Task Force on Multi-Agent Systems.
The group has also been involved in the organization of several special
sessions and panels under the scope on international conferences.
IES group has been developing several activities in close cooperation
with some companies (e.g. load analysis and forecasting with EDP –
Electricity of Portugal, intelligent support for Power Systems operation
and intelligent training with REN – Portuguese Transmission Network,
PowerConsult, Hungary and CHESF, Brazil, and several activities
related with energy efficiency and Energy Service Providing with
HARKER, SUMNER, S.A.).
This group has been cooperating with other research groups working in
related areas (e.g. INPG – Institut National Polytechnique de Grenoble,
France, led by Prof. Nouredine Hadjsaid, Santa Catarina Federal
-IES- 87
University, Brazil, led by Prof. Jacqueline Rolim, Fakultaet fur
Elektrotechnik und Informationstechnik Otto-von-Guericke -
Universitat Magdeburg, led by Prof. Zbigniew Styczynski, Department
of Electronic and Electrical Engineering-Institute for Energy and
Environment of the Strathclyde University, led by Prof. Jim McDonald
and Imperial College, led by Prof. Goran Strbac).
IES group has been actively involved in the organization of the
exhibition “Artificial Intelligence – 50 Years” held at ISEP. This group
contributed with several exhibited prototypes, namely concerning
electricity price forecasting, consumer clustering and classification, the
Expert System SPARSE-II and the Operators’ Training system SPARSE-
IT/ResTrain, both used by REN.

FUTUEN - Future Urban Energy Networks
Project Leader: Zita Vale
email: [email protected]
This project envisaged to investigate emerging electrical energy
production and transportation technologies (such as Distributed
Generation), and also the new forms of managing the networks (active
network management, new protection devices, storage, etc), and study
scenarios (some of which have are being developed under national
projects already running) for future networks in the 2020 to 2050
period.
The proposed work will focus around the joint needs (and wider EU and
world) for understanding in the UK and Portugal of future power
networks. The rapid pace of change in power networks expected in the
coming decades requires detailed analysis now, to enable the
development of power system planning, operation and management
methods fit for these future power systems. This work finds it context in
anticipated power network investments, the development of
renewable and alternative energy technologies and of course the all
pervasive implications of climate change.
This project involved the University of Strathclyde and GECAD.

PRODI - Management of Future Distribution Networks with Distributed Generation
Project Leader: Zita Vale
email: [email protected]
In the aims of the opening of the electricity market, following 96/92/CEE
document, considering the regulation of the electric sector, it was
expected the appearing of many small-scale electricity generators
connected to the electricity distribution network. This scenario will
dramatically change the power flows in the networks, as well as the
way they need to be managed and explored. Renewable energy
sources will see a great development. The objective of this Project is the
study of this scenario, where distributed generation will have a
significant impact in the distribution networks.
This project involves GECAD and the National Polytechnic Institute at
Grenoble, France.
-IES- 95

electricity companies in their operation in the new competitive market.
This project resulted also in a decision-support and information tool for
several kinds of final electricity consumers, providing them with advices
about the contracts that they can establish with electricity companies.
In this project are involved the following entities: GECAD, INTERG,
ISEC/IPC, and UTAD.
-IES- 96
IDDA – POCTI/34451 - Intelligent Distributed System for Power Distribution Automation
Project Leader: Zita Vale
email: [email protected]
In this project we claimed that the software interaction through agent-
based software engineering is suitable for the next generation of
Distribution Automation systems, leading to a philosophy of building
systems of smaller manageable components that can interact,
communicate and cooperate. In such Multi-Agent Systems knowledge,
resources, control and authority were distributed amongst community
members working together, in a co-ordinated and coherent manner, in
order to solve problems.
The Portuguese Distribution Company EN/EDP cooperated with
GECAD in this project.

DAMICE – POCTI/39744 - Power Systems Consumer Profiles and Contracting Strategies supported by Data Mining
Project Leader: Fátima Rodrigues
email: [email protected]
DAMICE (Power Systems Consumer Profiles and Contracting Strategies
supported by Data Mining) envisaged the application of Data Mining
and Knowledge Discovery techniques to the existing information about
electric energy consumers to obtain the characterization of different
consumer profiles. The obtained knowledge is important for the
suggestion of the most adequate contracts to be established. EDP
cooperated with GECAD in this project
-IES- 99
APRICOT – POCTI/47191 - Incident Analysis and Power Restoration with Intelligent Cooperative Operators Training
Project Leader: Zita Vale
email: [email protected]
The APRICOT project (Incident Analysis and Power Restoration with Intelligent
Cooperative Operators Training) deals with Intelligent Tutors aimed at training
electrical networks Control Centre operators in the tasks related with their dealing
with serious incidents in the network. The power system restoration problem is
basically a planning problem. Taken individually none of the tasks to be performed
during the restoration of a power system is fundamentally difficult. However, many
constraints must be checked repeatedly as these tasks are performed, and that
must be done under very stressing conditions. The current training programs are
based on the use of electrical network simulators. Albeit being very useful to
understand how an electrical network behaves, those tools don't provide user
modelling, don't evaluate student's performance and are quite inflexible in curricula
planning and training session’s preparation. On the other hand, Intelligent Tutors
are flexible tools and when provided with an adequate User Model, they can adapt
the training to the specific needs and characteristics of the trainee. One sub-goal of
this project is the development of a user modelling component capable of enabling
the Tutor to provide flexible guidance, adaptive curricula and didactic methods
selection. It also allows maintaining the trainee's work evaluation.
REN cooperated with GECAD in this project.

Agents&Markets - POSI/56260 - Agent based Market Simulation
Project Leader: Carlos Ramos
email: [email protected]
Agents&Markets (Agent-based Market Simulation) envisages the use of
Multi-Agent Systems technologies in Markets Simulation. This will be an
innovative proposal combining the following aspects: Agent-based
Simulation; Consumer Behaviour Model; Electronic Market Analysis;
Negotiation Mechanisms; Strategic Behaviours; Machine Learning and
Data Mining; and other participants’ behaviour analysis with Game
Theory. The basic idea of this project is to simulate markets using
Intelligent Agents technology in order to be exhibited a time-
dependant strategic behaviour, making decisions considering the other
participants behaviour (Consumer Behaviour Model, Game-Theoretic
based Scenario Analysis) and providing the automation of the learning
using the past interactions. The developed system will not be just a
Market Simulator. It is envisaged a tool to support decision-making for
one or more market participants. Two different test cases are
considered: Electricity Markets and Electronic Commerce.

FENDIN – POCTI/59807- Future Energy Distribution Networks
Project Leader: Zita Vale
email: [email protected]
The FEnDiN project is focused on the need to understand future distribution
networks (DN). The rapid change in power networks expected in the coming
decades requires detailed analysis now, to enable the development of power system
planning, operation and management methods adequate to these future power
systems, and grant for sustainable development. The aim to provide power systems
that can fulfil their goals and guarantee the required conditions for sustainable
development requires to significantly increasing the penetration of Distributed
Generation (DG) to such levels that are not compatible with the methods used for
planning, operating and managing today DN.
The central aim of this project was to create new means to plan, operate and
manage the future electrical power supply and DN, in a competitive market
environment, searching for technical solutions to allow suitable migration between
today electrical networks to the future ones.

ViP-DiGEM - PTDC/ 72889 - VIrtual power Producers and DIstributed Generation trading in Energy Markets
Project Leader: Zita Vale
email: [email protected]
This project aims to provide an organizational and technical framework to enable
the trading of electrical energy produced in a distributed way, based mainly on
renewable sources (RS), in a competitive electricity market (EM).
The goal is to consider technical and financial issues providing the basis for efficiently
including RS-based electrical energy in EM, increasing its financial value and
consequently its weight in daily traded and consumed energy, with gains for all
(producers, consumers, Society in general, due to better RS usage and positive
ambient impact). High security and reliability standards for Power Systems (PS) are
considered.
The intermediate goals of the project are: the modelling and simulation of EM and
Virtual Power Producers (VPP) and their relations using Multi-Agent System
technology, combined with other technologies like Machine Learning and Game
Theory; and the modelling, simulation and study of aggregations of market agents,
resulting in concrete tools to bring the concept of VPP to practice.
-IES- 103
RiMaCEM – PTDC/69102 - Risk Management in Competitive Electricity Markets
Project Leader: Zita Vale
email: [email protected]
This project is coordinated by Zita Vale. The main goal of the Project is to overcome
some difficulties that liberalized Electricity Markets (EM) have been experiencing.
This project aims at proposing and implementing new price forecasting methods
adequate to support decision making in EM. Existing EMs have not adequately
succeeded in reflecting in commercial transactions the requirements of technical
operation of Power Systems (PS). One of this project’s goals is to propose and
implement new methodologies for: 1 – Re-dispatch under congestion situations -
The main goal is to guarantee the respect of technical restrictions with minimal
changes in the transactions resulting from market negotiation; and 2 – Transmission
tariffs - The main goal is to adequately reflect the technical requirements of PS
operation in transmission tariffs giving sellers and buyer adequate signs for their
participation in EM.
This project involves GECAD and ISEL.

Research Group on Knowledge & Learning Technologies
(K<)
-K<- 112
-K<- 113
Introduction to Knowledge & Learning Technologies (K<) group Knowledge-based Systems (KBS) correspond to an area where there is
an explicit separation between Knowledge and Inference. Expert
Systems, Data Mining, Intelligent Tutors are examples of KBS.
Knowledge play an important role in KBS. Nowadays, Ontologies are
receiving attention, namely due to the importance of concepts and
their relation for the Intelligent Agents, Semantic Web, and
Knowlewdge Management.
Machine Learning techniques envisage obtaining automatically, or
semi-automatically, knowledge from data. Neural Networks, Decision
Trees, Case-based Reasoning are just some of the used techniques. Data
Mining joins AI based Machine Learning with Statistics based techniques
(e.g. K-means) to allow a powerful set of tools to be used in the
Knowledge Discovery effort in Information Systems.
The main objective of the Knowledge & Learning Technologies group is
to concentrate critical mass around these technologies in order to allow
a Knowledge Society and Economy built in a correct way. We claim
that “Knowledge” must not be seen just as one more keyword, and that
without agents with Knowledge and Machine Learning technologies the
Knowledge Society and Economy will be too limited.
The main areas where this group works are:
- Expert Systems
- Intelligent Tutoring Systems
- Ontologies
- Machine Learning, Data Mining, including Neural Networks
- Intelligent Agents
- Semantic Web
- Knowledge Management
-K<- 114
Knowledge & Learning Technologies group has obtained a meaningful
scientific recognition during the last years.
This recognition is clear from the quality of the main publications, in
scientific journals with high impact factors (e.g. the maximum is 2.202,
and other 5 publications are close to 1).
During the last years this group had 6 projects (SANSKI, DAMICE,
ONTOMAPPER, EDGAR, Agents&Markets, EMUSSL, and TINSEL) and 3
new project will start in 2007 (IFRA, COPSRO, and COALESCE).
The group covers a great variety of areas. The area of Data Mining is
obtaining results at different levels, namely in terms of publications, but
also in projects (DAMICE, EMUSSL and more recently COPSRO and
IFRA). The area of Ontologies has obtained results in the projects
(SANSKI, ONTOMAPPER, and EDGAR, and more recently in IFRA and
also in COPSRO) and in good international connections. The area of
Intelligent Tutoring Systems has the TINSEL project and also cooperates
with the Intelligent Energy Systems group in another project (APRICOT).
The area of Intelligent Agents has also importance due to the
Agents&Markets project and also due to the publications. Notice that
Agent-based systems are a technology covered by all groups of GECAD.
Cooperation with international groups is established in several works,
namely in Ontologies. Two researchers of this group, Nuno Silva and
Jorge Santos, were during some months in Germany in FZI
(Forschungzentrum Informatik) and AIFB (Angewandte Informatik
und Formale Beschreibungsverfahren) where they contacted with some
of the most prominent researchers of Ontologies (Steffen Staab,
Alexander Maedche, Rudi Studer, and Rudi Studer). As a result of the
stay there, two world reference platforms (MAFRA and FONTE) were
developed by our researchers. These platforms are now used in 4
European R&D projects, namely, in Harmonise (IST-2000-29329),
Harmo-Ten (eTEN C510828), Satine (IST-1-002104-STP), and Artemis
-K<- 115
(IST-1-002103-STP). Publications with international authors have also
been done in Ontologies, Intelligent Agents and Data Mining areas.

SANSKI - POCTI/41830- Semi-automatic Negotiation Services for Knowledge Interoperability
Project Leader: João Rocha
email: jsr@ isep.ipp.pt
SANSKI (Semi-automatic Negotiation Service for Knowledge
Interoperability) is a project supported by FCT that started in
January/2002 with the duration of 3 years. This project proposed
approaches, methodologies and solutions, respecting the negotiation
and translation of communication parameters, namely concerning
knowledge sharing models, in order to achieve interoperability between
heterogeneous entities. Several prototypes were developed in order to
validate the suggested approaches.

DAMICE – POCTI/39744 - Power Systems Consumer Profiles and Contracting Strategies supported by Data Mining
Project Leader: Fátima Rodrigues
email: [email protected]
DAMICE (Power Systems Consumer Profiles and Contracting Strategies
supported by Data Mining) envisaged the application of Data Mining
and Knowledge Discovery techniques to the existing information about
electric energy consumers to obtain the characterization of different
consumer profiles. The obtained knowledge is important for the
suggestion of the most adequate contracts to be established.
EDP cooperated with GECAD in this project.

ONTOMAPPER - POSI/41818- Ontology Automatic Mapping
Project Leader: João Rocha
email: jsr@ isep.ipp.pt
ONTOMAPPER (Ontology Automatic Mapping) is a project supported
by FCT that started in March/2002 with the duration of 3 years. The
correct and coherent knowledge definition, its representation,
communication, share and respective methods, give rise to several
problems. Also, when adopting and sharing ontologies, the elements to
reason about knowledge exist, but other complementary processes are
needed in order to entities agreed on the models and its meanings. In
this project it was suggested to employ standard technology, like the
FIPA and KQML agent communication languages (ACL), emergent
standards for representing and structure information like XML/S, RDF/S
and DAML+OIL. Concerning ontologies, recent tools like OILEd and
OntoEdit ontology editors, Protégé as a methodology and Ontobroker
and FaCT based reasoning engines were used.
-K<- 124
EDGAR - POSC/61307 - Exploiting Ontology Engineering Process Information for Semi-Automatic Knowledge Interoperability
Project Leader: João Rocha
email: jsr@ isep.ipp.pt
MAFRA Toolkit is a service-oriented tool for mapping ontologies
developed by the research team of this Project. Semantic bridges have
a limited support in this tool.
Although all the advantages of this approach, several semantic
relations are suggested for the same entities’ group. These are clearly
ambiguity situations, since many services are activated due to a
reduced number of imposed constraints.
EDGAR project envisages providing the decreasing of the number of
ambiguous resulting from the similarity measures. Research in the áreas
of Ontology merging and pattern-based Ontology Engineering are
being used. A formal approach, using another platform developed by
this group, FONTE, is used.

Agents&Markets - POSI/56260 - Agent based Market Simulation
Project Leader: Carlos Ramos
email: [email protected]
Agents&Markets (Agent-based Market Simulation) envisages the use of
Multi-Agent Systems technologies in Markets Simulation. This will be an
innovative proposal combining the following aspects: Agent-based
Simulation; Consumer Behaviour Model; Electronic Market Analysis;
Negotiation Mechanisms; Strategic Behaviours; Machine Learning and
Data Mining; and other participants’ behaviour analysis with Game
Theory. The basic idea of this project is to simulate markets using
Intelligent Agents technology in order to be exhibited a time-
dependant strategic behaviour, making decisions considering the other
participants behaviour (Consumer Behaviour Model, Game-Theoretic
based Scenario Analysis) and providing the automation of the learning
using the past interactions. The developed system will not be just a
Market Simulator. It is envisaged a tool to support decision-making for
one or more market participants. Two different test cases are
considered: Electricity Markets and Electronic Commerce.

TINSEL - POSI/61843 – Intelligent Tutors for Electrical Installation Design
Project Leader: Luiz Faria
email: [email protected]
Electrical Installations design combines academic and empirical
knowledge.
TINSEL project envisages the development of an Intelligent Tutoring
System to support Electrical Installations designers, technical staff and
Electrical Engineering students.
The Project involves the development of the user model in order to
support the pedagogical options of the tutoring system. A library with
real cases will be used in the mapping of the main features of the cases
with the domain concepts. Case-based reasoning will be used to select,
adapt and store real cases, allowing to customize courses and to
improve the adaptive capabilities to the trainee. Grouping and
Comparison techniques will be used in the definition of the students’
stereotypes.

EMUSSL - POSC/61924 - Ensemble Methods for Unsupervised and Semi-Supervised Learning
Project Coordinator at GECAD: Fátima Rodrigues
email: [email protected]
Data clustering or unsupervised learning is an important but difficult
problem. The objective of clustering is to partition a set of unlabelled
objects into homogeneous groups or clusters. Quantitative evaluation of
the quality of clustering results is difficult due to the inherent
subjectivity of the notion of cluster. Semi-supervised learning algorithms
make use of both labelled and unlabelled samples and have been the
focus of much recent research by the machine learning and pattern
recognition communities. Semi-supervised learning has been typically
viewed from a supervised learning point of view, as a being a
classification problem with some missing labels. This perspective suggests
the use of supervised ensemble methods to semi-supervised problems.
This research direction will be exploited in the project. Additionally, one
of the main threads of this project will be to address semi-supervised
learning as an unsupervised learning problem with some additional
knowledge/constraints. This perspective will allow semi-supervised and
unsupervised problems to be addressed in an integrated fashion, which
we will do with a strong emphasis on ensemble methods.
This project involves IT (Telecommunications Institute) and GECAD.

IFRA - PTDC/70168 - Improving Financial Risk Analysis with advanced Data-Mining tools
Project Coordinator at GECAD: Armando Vieira
email: asv@ isep.ipp.pt
Predicting when a company may declare bankruptcy is a problem of
great importance for creditors - banks, bondholders and suppliers - and
also for other stakeholders such as shareholders, employees, customers
and State.
In an increasingly globalized economy, bankruptcy results both in huge
economic losses and tremendous social impact. More important than
predicting the insolvency is to determine the probability to become so.
This is a complex problem, normally analysed by conventional statistical
techniques such as Linear Discriminant.
However recent techniques, as Genetic Algorithms, Neuronal Networks,
and Support Vector Machines had shown to be more robust and
efficient to analyze this type of problem as well as related others. The
objective of this project is to use these techniques of data classification in
the field of financial risk and decision support, namely bankruptcy
prediction.
This project involves IST, University of Coimbra, University of Minho, and
GECAD. The Bank of Portugal will cooperate in this project.

COPSRO - PTDC/EIA/69988/2006 - Computational Approach to Ontology Profiling of Scientific Research Organisations
Project Coordinator at GECAD: Fátima Rodrigues
email: [email protected]
The main objective of this research work is to develop a methodology
for ontology profiling scientific research organisations, including:
-A reliable and valid research subject extraction method developing
text mining techniques.
-An effective method for establishing within-organisation similarities
between the ontology items.
-Adequate clustering methods for representing a research organisation
by a set of possibly overlapping or fuzzy subject clusters.
-Optimally mapping the subject clusters to the subject area ontology to
reveal organisation’s profile.
-Interpretation and evaluation of individual organisation profiles.
-Combination of individual profiles into an aggregate profile.
-Characterization of aggregate profiles by rule extraction.
-Experimental verification of the method.
The proposed methodology will be applied to scientific research
organisations of computer science, specifically, Computer Science
Departments of Universities in Portugal and UK, having as ontology of
reference the ACM Classification System. This project involves CENTRIA
and GECAD.

COALESCE - PTDC/EIA/74417/2006 - Collaboration-based Information and Recommendation Retrieval Systems
Project Leader: Nuno Silva
email: [email protected]
In order to take advantage of the huge amount of data on the Web,
one has to collect, filter and assemble it, relating facts and documents,
as well as considering the use that each one (or community) makes of
them.
The project aims to research on methods and tools able to simplify and
automate the management of information, through retrieval,
integration and recommendation of information from multiple public
and private repositories in a semantic (described through ontologies or
folksonomies) and recommended fashion (according to semantic social
networks emerging in the context of the Social Web.
The envisaged system will be wrapped-up with a tool in the form of a
Semantic Desktop, as the interface between the user and public
repositories, either on the Web, PCs or mobile devices. As the Semantic
Desktop and complementing technologies improves their features, the
local vs. Web dichotomy tends to disappear, promoting the
transparency between the physical location and type of information.
