Our current climate is one of ever increas-ing amounts of information, and queriesthat require the intelligent integration ofvaried and potentially vast informationsources. It is essential now more so thanever that we extend our abilities to searchand exploit information both more accu-rately and more efficiently, and makeconnections readily between varied infor-mation sources. This goal is best achievedby leveraging the efforts of both the IRand agents communities.
This workshop will focus on the appli-cation of agent-based and multi-agentsystem technology to the problems ofstoring and searching large collections ofdocuments. This includes traditional in-formation retrieval questions such as re-trieval effectiveness and system perfor-mance. We also address agent-based ap-proaches to distributed IR, where theagents (and documents) are scattered, forexample, among the nodes of a network.Agent-based systems are also appropriateto the task of searching or even integrat-ing heterogeneous sources of informa-tion, and the fusion of results.
TopicsWe encourage submissions in the follow-ing areas:
■ Query formulation■ Processing of standing/ad hoc queries■ Use of ontologies in corpus selection■ Metadata■ Specialized protocols for distributed IR■ Performance modeling and evaluation
Participation will be limited to fifty indi-viduals, by invitation.
SubmissionsThose interested in participating shouldsubmit (to [email protected]) either: (1) Briefstatement of interest (one page), or (2)Complete paper (no more than eightpages) including keywords and authors'complete addresses.
Papers and statements of interest
should be in PostScript, PDF, or HTMLformat. Direct all inquiries by email tothe chair, R. Scott Cost.

Agent-Based Systems for Information Retrieval
With the increasing acceptance of the In-ternet, various technologies have beenused to manage and automate onlinebusiness. Currently, there is a large bodyof work supporting the use of intelligentsoftware agents in electronic commerce.To date, the majority of this work has fo-cused on agent-supported collaborationsbetween online businesses and con-sumers (B2C). Currently, an increasingamount of agent research has been direct-ed toward B2B domains. The large major-ity of this work supports common artifi-cial intelligence approaches to automatednegotiation and pricing, auctioning andtransactional reasoning, business-orient-ed ontological representation and learn-ing, and the control of workflow or sup-ply chain management among onlinebusinesses. In drawing a distinct line be-tween agent-oriented B2C commerce andagent-oriented B2B commerce, we invitemanuscripts from researchers and indus-try labs that are specifically working onthe underlying concepts, architectures,representations, and implementations foragent-oriented B2B commerce.
Topics■ Modeling, designing, and developing
software agents-oriented workflow■ Agent-based coordination and commu-
nication languages for electronic markets■ Software agent architectures for B2B or
B2C coordination and interoperation■ Agents for the representation and col-
laboration of business integrationknowledge
FormatThis three-part workshop will be com-prised of papers on agent-oriented con-cepts and methodologies for B2B interop-erability, papers on the underlying B2BAgent applications and architectures, andpanel sessions that showcase agent re-search that supports the diverse underly-ing areas.
AttendanceParticipation will mostly be limited to sub-mitted papers. Researchers who would liketo participate in the panel sessions shouldcontact the workshop chair. We anticipateadmitting 40 persons to the workshop.
SubmissionsSubmissions should focus on the AI andagent-oriented aspects that automate B2Binteroperability over the Internet. Sub-missions must be formatted in accor-dance with the AAAI guidelines and sub-mitted electronically (PDF is preferred) tothe workshop chair. Papers should notexceed 10 pages, and all submissionsshould be made in accordance to theAAAI workshops timetable.

Artificial Intelligence for Intelligent Business
As the cognitive and physical health ofelders begins to deteriorate, they requireincreasing assistance from caregivers. Thestrain on families and individuals is enor-mous. In many cases people are turningto technological solutions to aid in caregiving for this elderly population. Whilemuch of this technology continues to oc-cupy traditional assistive roles such aswalking, door opening and communica-tion, increasingly advanced technologicalsolutions are now being proposed and de-veloped to aid in monitoring, cognitivesupport and direct automation of tasks.In addition, failure to consider the hu-mans' needs, desires, capabilities and lim-itations will lead to unsatisfactory tech-nological solutions at best, and disastersat worst.
By bringing together researchers fromrobotics, artificial intelligence and humanfactors, this workshop will help foster acoordinated solution for automation ascaregiver for the elderly. We are interest-ed in submissions covering both integrat-ed solutions as well as particular compo-nents.
TopicsAssistive technology: Devices that aid withmobility, medication management, andhousehold tasks.
Cognitive aids: Technology that sup-ports declining cognitive skills, includingreminders, task instruction, and methodsto reduce cognitive effort.
Passive monitoring: Devices and reason-ing systems that recognize the elder's ac-tivity and learn to detect abnormal situa-tions.
Decision-making: Reasoning systemsthat respond to situations and the elder'sneeds by interacting with devices in thehome, interacting with the elder, or con-tacting caregivers.
Human factors: Interfaces that meet el-der's needs and capabilities—motor, sen-sory and cognitive.
Adaptation: Techniques to recognizethe elder's changing capabilities.
Specific technologies that support oneor more of these areas include robotics,computer vision, speech understanding,knowledge representation, planning, ma-chine learning, situation assessment, tasktracking, agents, software architecturesand human computer/robot interfaces.
FormatThe technical program will include pre-sentations on contributed papers, paneldiscussions, and an invited talk by a geri-atric specialist, describing the reasons el-ders move out of their homes, and poten-tial roles for automation. Attendance islimited to 50 participants. Nonpresentersinterested in attending should submit aone-page statement of interest to the or-ganizers.
SubmissionsSubmissions should be no more than 5pages and formatted according to theAAAI style files. Send papers via email toKaren Haigh (PDF or PostScript).

Automation as Caregiver: The Role of Intelligent Technology in Elder Care
Following successful recent workshops onsocial notions of multiagency, we are in-terested in scaling issues of social net-works on inter-group interactions. Theo-ries are needed to synthesize the inter-agent interaction into unified models.Derived and implied attitudes are beyondthe immediate and direct inter-agent atti-tudes but play a big role in balance of at-titudes among agents in a group. We callupon several research camps with differ-ing perspectives on related issues includ-ing the following: human-robot interac-tion, human-computer interaction,agent-agent interaction, and organiza-tional theory. We continue to strive forcommonalities across research camps.
AttendanceWe are seeking papers that clearly exem-plify central notions in a research campor try to synthesize unified views. To en-courage interaction and a broad exchangeof ideas, the workshop will be limited to40 participants and ample time will be al-lotted for general discussion.
SubmissionsAuthors should submit an extended ab-stract (3-4 pages) or a full paper of up to 8pages. Manuscripts are expected to be inEnglish (with American spelling pre-ferred). Our first preference is HTML files.Otherwise, we prefer the following for-mats: MS word, PDF, PostScript. If we re-ceive an adequate number of quality pa-pers, we will seek to publish them as acollection.

Autonomy, Delegation, and Control:From Inter-Agent to Groups
Dynamic real-world environments posedifficult challenges for rational agentswho might otherwise be capable of form-ing optimal coalitions for problem solv-ing under conditions of perfect informa-tion and unlimited computational re-sources. In dynamic environments whereevents are changing rapidly and informa-tion cannot be relayed among the agentsfrequently enough or centralized updatesand polling are expensive, agents may beforced to form suboptimal coalitions. Insuch instances, agents need to balancecoalition quality with the quality of theavailable information (which will typical-ly be both incomplete and uncertain) aswell as the availability of computationalresources. This may involve characteriza-tions of domains in terms of appropriatecoalition formation strategies or the de-velopment of approaches for learningbetter formation strategies over time.More importantly, while agents interactover the impact of such issues as task al-location and information exchange oncoalition formation, agents will at thesame time need to remain collectively re-sponsive to their environments. This re-quires that agents be “time aware” andconduct real-time/soft real time delibera-tion about coalition formation whilemaintaining domain activities.
Topics■ Real-time dynamic coalition formation■ Coalition formation under uncertainty
and suboptimality■ Negotiation-based coalition formation■ Task allocation (or job matching)
strategies among agents of a coalition■ Coalition formation for resource allo-
cation■ Anytime/adaptive coalition formation
strategies■ Learning of better coalition formation
strategies■ Multiagent coordination through
coalition formation
■ Cross-coalition interaction and hierar-chical organizations
FormatThe workshop will consist of two generalsessions: morning and afternoon. Eachsession will include presentations (abouttwenty minutes each) and a one-hourpanel discussion. The morning discussionwill be on the issues of coalition forma-tion when information is incomplete oruncertain, while the evening discussionwill be on soft real-time, time sensitive,or resource bounded coalition formation.
SubmissionPotential participants should submit ei-ther an extended abstract (up to 3 pages)or an original technical paper (up to 10pages) including keywords and authors'complete addresses. Submit electronically(in PostScript or PDF format) to [email protected].

Coalition Formation in Dynamic Multiagent Environments
Research in robotics has traditionally em-phasized low-level sensing and controltasks including sensory processing, pathplanning, and manipulator design andcontrol. In contrast, research in cognitiverobotics is concerned with endowingrobots and software agents with higherlevel cognitive functions that enablethem to reason, act and perceive inchanging, incompletely known, and un-predictable environments. Such robotsmust, for example, be able to reasonabout goals, actions, when to perceiveand what to look for, the cognitive statesof other agents, time, collaborative taskexecution, etc. In short, cognitiverobotics is concerned with integratingreasoning, perception and action withina uniform theoretical and implementa-tion framework.
This workshop aims to bring togetherresearchers involved in all aspects of thetheory and implementation of cognitiverobots, to discuss current work and futuredirections. While all aspects of cognitiverobotics are of interest to the workshop,we especially welcome discussions anddemonstrations of implemented systems.CogRob2002 follows the very successfulAAAI 1998 Fall Symposium on CognitiveRobotics held in Orlando and the SecondInternational Cognitive Robotics Work-shop, held in conjunction with ECAI-2000.
SubmissionsPotential participants are invited to sub-mit either a technical paper (extended ab-stract), an overview paper on their ongo-ing research, a position paper, or a de-scription of an implemented system thatthe authors are willing to demonstrate atthe workshop. Papers should be nolonger than 7 pages with a font size of atleast 10 points. Others wishing to attendshould submit a 1-2 page description oftheir work or interest in this area (includ-
ing a short list of related publications).This may include specific questions andissues that they feel should be addressed.Proposals of panels on specific issues arealso welcome.
Papers submitted to this workshop arenot considered to be archival publica-tions. Working notes will be distributedat the workshop, but no archival publica-tion will be produced. Hence, authorsmay submit papers that are under reviewelsewhere, or that will be published else-where, including KR2002 and AAAI-2002.Electronic submissions are preferred andshould be sent to [email protected]. Papers must be in PostScript.

Cognitive Robotics
Over the last few years, game and deci-sion theories have proved to be powerfultools with which to design autonomousagents, and to understand interactions insystems composed of many such agents.Decision theory has been adopted as aparadigm for designing agents that canhandle the uncertainty of any moderatelycomplex environment, and act rationallyto achieve their goals. Game theory,largely assuming the existence of self-in-terested agents, has been employed in thedesign of mechanisms and protocols forinteraction, coordination, communica-tion, negotiation, coalition formation,fair voting techniques, market-based re-source management systems, and indus-trial-scale information economies.
As a result, there seems to be much togain from bringing together researchersinterested in game theory and decisiontheory to present recent work on the ap-plication of these techniques in the con-struction of agent systems, and to discussthe cross-over between the fields. Thishas been bourne out by the three previ-ous GTDT workshops. The fourth GTDTworkshop will continue to provide a fo-rum for the presentation and discussionof results in game theory and decisiontheory applied to agent-based computing.
SubmissionsPlease submit the paper electronically (atmost 15 pages standard LaTeX articlestyle) in PostScript (preferred) or in PDF,to Piotr Gmytrasiewicz at [email protected].
TopicsWe solicit papers dealing with, but notlimited to, the following areas:
■ Descriptions of agent systems employ-ing game theory or decision theory
■ Empirical evaluations of agent systemsemploying game theory or decisiontheory
■ Theoretical developments in game the-
ory or decision theory applied to agentsystems
■ Position statements about the use ofgame theory or decision theory inagent systems
Descriptions of deployed systems arewelcome. We are also interested in theuse of non-standard variants of decisiontheory (including qualitative and logicalapproaches), and in approaches thatcombine decision and game theories.

Game Theoretic and Decision Theoretic Agents
The evolution of the world wide webfrom a repository of data (in static webpages) to a source of varied distributedservices creates exciting opportunities foroffering integrated, distributed servicesover the web, for applications such ascomparison shopping, trip planning, sup-ply chain management, complex productconfiguration, and remote medical recordquery.
However, such opportunities comewith their own challenges. Services fromdifferent providers need to be integratedinto a single composite service that ap-pears as a seamless whole. The syntacticproblems of such integration are beingaddressed by the advent of XML-basedstandards for information interchange,and web-based exchange protocols likeSOAP. However, the promise of serviceintegration will not be delivered, unlessservices can be integrated semantically aswell.
TopicsWe encourage submissions that treat top-ics anywhere in the spectrum of solutionsto semantic service integration problems,ranging from standards-based (e.g., indus-try-specific XML standards) to just-in-time (e.g., wrappers and mediator archi-tectures).
In this workshop, we plan to bring to-gether researchers working on various as-pects of this problem, including architec-tures for semantic integration, protocolsand representation languages for infor-mation interchange for service integra-tion, semantic matching systems, andmanagement of integrated services.
SubmissionsThe workshop will be a mix of presenta-tions followed by discussions and a panelsession. The final topic and constitutionof the panel will be decided from the sub-missions, but will probably cover a rangeof approaches to intelligent service inte-
gration. We envision four types of sub-missions: (1) position papers providingunique insight into the challenges of in-telligent service integration, (2) applica-tion papers describing systems that ac-complish run-time semantic integration,(3) descriptions of architectures, represen-tation languages or protocols for achiev-ing service integration, and (4) other sys-tems for solving specific problems relatedto service integration (e.g., semanticmatching, translation, wrapper genera-tion, etc.). Electronic submission(PostScript or PDF) is preferred. Submit-ters who wish to be considered as pan-elists, should indicate this in their work-shop submission.
CommitteeThe workshop cochairs are Dean Alle-mang, Boston University ([email protected]) and Eleni Stroulia, University of Al-berta ([email protected]). Also serv-ing on the workshop committee is JohnMylopoulos, University of Toronto([email protected]).

Intelligent Service Integration
The design of intelligent situation-awaremedia and presentations becomes in-creasingly important for software design-ers and also for the design of consumerelectronic devices. This process is due tothe fact that software becomes more com-plex and systems become integrated intoa ubiquitous information infrastructure.The paradigm of “one device—one func-tionality” is over and today we can accessmutually any service through any device.A TV set for instance is nowadays a con-trol center for various applications, e.g.,video programming, e-commerce, web-browsing and more. A mobile PDA can beused as a telephone, tourist guide, remotecontrol, and calendar or web-access de-vice.
In these scenarios, new intelligentmethods are necessary, that decouple theapplication logic from the actual deviceand that adapt the media and presenta-tion to the actual situation, i.e., the userwith her needs and preferences, the de-vices that are available, and the context.
TopicsIn the ISAMP workshop we intend tobring together researchers working onvarious aspects of the problems describedabove. The scope of interest includes butis not limited to:
■ Adaptive media for single modalities(vision, audio, etc.)
■ Context-aware presentation manage-ment
■ Device-adaptive dialog systems■ Seamless presentation management in
ubiquitous computing■ User-adaptive media■ Situation-adapted user interfaces■ Adaptation to limited technical re-
source and cognitive resources
SubmissionsWe encourage submissions from re-searchers and practitioners in academia,industry, government, and consulting.
Students, researchers and practitionersare invited to submit full papers (max 8pages) or suggestions for demonstrations(max 4 pages) describing original, novel,and inspirational work. Submissionsshould be sent by email to Rainer Malaka([email protected]).

Intelligent Situation-Aware Media and Presentations
The development of distributed applica-tions over large networks of computersraises the issue of semantic interoperabilitybetween autonomously developed sourcesof information or service providers. Theproblem seems especially critical in areaslike knowledge management, semanticweb, web services.
A common strategy for dealing with se-mantic interoperability is to create large,shared conceptual schemas (e.g. ontology,web directories, taxonomies) that are usedas a common reference for concepts be-longing to heterogeneous schemas. How-ever, there are practical and theoreticalreasons why this can't work on a very largescale. This workshop aims to explore an al-ternative approach, based on the intuitionthat humans overcome semantic hetero-geneity through meaning negotiation(MN)—an activity that aims at finding anagreement on the meaning of the expres-sions that are used in linguistic communi-cation. By definition, MN involves seman-tically autonomous entities, namely enti-ties that cannot assess a semantic problemby “looking into each other's head;” MNdoes not exclude that semantically autono-mous entities may share objects or artifactsin some environment, but that is not liketaking for granted that this is sufficient toguarantee successful communication.
The problem of meaning negotiationcan be addressed from many different per-spectives, using different conceptual andtechnological tools, and with differentmotivations in mind. We welcome contri-butions from a variety of fields, such asknowledge representation, multi-agentsystems, databases, natural language pro-cessing, machine learning, game theory,epistemology, philosophy of language,cognitive science, psychology, sociology,organization and management sciences.
TopicsTopics of interest include (but are notlimited to):
■ Formal, computational, game-theoret-ic, cognitive, epistemological, socialmodels of MN
■ Multiagent communication protocolsfor supporting MN
■ Ontology, database and XML schemasintegration/mapping
■ Natural language processing tech-niques for MN
■ Applications of game theory to MN■ Coordination/cooperation through MN■ Innovative scenarios for MN (such as se-
mantic web, knowledge management, e-business, marketplaces, personal digitalassistants, mobile applications)
■ Business cases
FormatPaper presentations and discussion/brain-storming. Presentations will be limited to15 papers.
SubmissionsAuthors are required to submit an ex-tended abstract (two, maximum threepages, formatted using the sample macrosavailable on the AAAI web page). The useof LaTeX is strongly encouraged.

Meaning Negotiation
The workshop focuses on multi-agentmodeling framework and simulationmethod of economic systems. By eco-nomic system, we mean a weakly con-nected multi-agent system where chain ofexchange exists, i.e., goods, currency,credit and information is continuouslyexchanged in the system.
The target system under analysis isnot limited only to financial market orwhole economy system, but also to sys-tems where the chain of exchange exists,such as shopping system consisting ofcustomers and shop keepers, marketmechanism for environment protection(recycling, greenhouse gas emissions), hu-man or vehicle flow where exchange ofphysical status and information occurs,and so on.
The primary purpose of the workshopis to reveal the mechanisms of phenome-na emerging from the chain of exchange.For the purpose, we think that computa-tional methods for modeling and simu-lating economic systems as multi-agentsystems are indispensable. More precisely,we intend to compare the computationalmethods for the following research goals:
■ Analysis of economic multi-agent sys-tems and to measure their complexity.
■ Analysis of the agent strategy underdynamically changing environment.
■ Relation between the complexity ofwhole system and the complexity ofagent strategy.
■ Common modeling and simulationplatform.
The technical issues to be discussed in-clude, but are not limited to:
■ Formal multi-agent modeling of eco-nomic systems, approached by agentarchitecture logic, game theory, cellu-lar automata, or mathematics
■ Multi-agent simulation of economicsystems
■ Mathematical analysis of simulationresults
■ Statistical analysis of economic multi-agent systems, e.g., econophysics
■ Analysis method of relation betweenwhole system and agents
■ Formal modeling of agent interactionin economic context
■ Designing and analysis of economicagents
■ Computational tools and platforms ofmulti-agent economics and economicagents
FormatWe plan to have the following sessions:Invited talks from both artificial intelli-gence and economics side by MichaelWellman (University of Michigan) andJohn Duffy (University of Pittsburgh); apanel session; and regular oral presenta-tions. Invitation is determined by review-ers' comments and the interest in the re-search topics. Submissions from both AIand economics are welcome.

Multi-Agent Modeling and Simulation of Economic Systems
This workshop will address ontologies forthe semantic web. The notion of the se-mantic web as promoted by Tim Berners-Lee and by Jim Hendler as the focus of amajor DARPA-funded research effort, is totransform the current world wide web sothat the information and services are un-derstandable and useable by computers aswell as humans. The semantic web willcreate an environment where softwareagents can readily perform sophisticatedtasks and help humans find, understand,integrate, and use information. the keydistinguishing feature of the semantic webwill be ontologies that will enable softwareagents to find the meaning of the informa-tion on web pages by following hyperlinksto definitions of key terms and rules forreasoning about them logically. The aimof this workshop will be to make progresson addressing what ontology languages,tools, methodologies, and content areneeded to support the semantic web.
TopicsPapers are solicited that discuss issues re-lated to the content of ontologies with re-spect to either presenting particular onto-logical content that is believed to be ofgeneral interest, or discussing the moregeneral issue of how a body of formal on-tology content can be extended or em-ployed in some application. Papers maypresent ontologies and discuss their valueor discuss issues in the standardization ofontological content.
■ How can the quality of ontologies beevaluated?
Papers are particularly encouraged thatprovide methodologies and test cases.
■ How can ontologies developed for thesemantic web be shared and com-bined?
Papers are particularly encouraged thatcontain specific use scenarios in whichsharing, merging, translating, etc. arecritical.
■ Use cases for ontological content onthe web.
A great effort is going into languages fordefining, and tools for manipulating, on-tologies on the web. Papers are encour-aged that describe either implementedapplications that make use of web on-tologies, or vision papers that describehow ontological content will change theweb.
FormatSubject to a sufficient response to our callfor participation, we are planning on atwo-day workshop. The agenda will con-sist of position statements by the pro-gram committee, invited talks, paper pre-sentations, and panel-led discussions.
Attendance will be limited to authorsof accepted papers and invited presenters.Other attendees will be accepted only ifspace permits. There will be a total of 25-65 participants.
SubmissionsPapers of 4-10 pages will be accepted byemail in PDF (preferred), PostScript orRTF formats to ([email protected]). Papers must conform to AAAIformat.

Ontologies and the Semantic Web
Multiagent systems (MAS) have becomean important subfield of AI, and severalclassical AI topics are now broadly stud-ied in their MAS (i.e. distributed) vari-ants. Multiagent planning (MAP) extendsclassical AI planning to domains whereseveral agents can plan and act together.Application areas of MAP include multi-robot environments, cooperating Internetagents, logistics, manufacturing, militarytasks, etc.
While related MAS disciplines (e.g.distributed constraint satisfaction) havebenefited from standardized problemspecifications and benchmarks, existingwork on MAP is still very heterogeneous.Approaches differ for example in theiremphasis on either the distributed plan-ning or the distributed plan executionprocess, in the ways communication andperception are used, and in whether aglobal plan for all agents or a local planfor each agent is produced. Some of theunderlying questions have been recentlyaddressed in related fields, such as in ex-tensions of classical planning to concur-rent plan models or in distributed ver-sions of heuristic search algorithms, butthe diversity of MAP approaches makes itdifficult for MAP research as a whole tobenefit from these developments.
Therefore, this workshop intends tobring together researchers working onany form of multiagent planning or in re-lated fields to discuss their common anddiffering goals and research methods, andto identify potentials for collaborationand cross-fertilization.
Topics■ Formalizations of the multi-agent
planning problem■ Description languages for MAP■ Distributed planning algorithms■ Centralized planning algorithms for
concurrent MA domains■ Distributed plan execution■ Distributed scheduling
■ Communication in MAP■ Privacy issues in MAP■ Deliberative versus reactive planning
in (highly dynamic) MAS■ MAP applications: systems and do-
mains■ Evaluation, benchmark problems, stan-
dards
FormatThe 1.5-day workshop will include invit-ed speakers, topically grouped and mod-erated presentations of submitted papers,and above all, extensive panel and opendiscussions on key topics of MAP and di-rections for joint post-workshop efforts.
SubmissionsThe workshop will be limited to 40 to 60invited participants. Persons interested inattending should electronically submit ashort paper (up to 6 pages) or positionstatement (up to 2 pages) to MichaelBrenner ([email protected]). Submitted research papersshould be in PostScript or PDF formatand use the AAAI style sheet.

Planning with and for Multiagent Systems
Preferences are gaining more and moreattention in AI and CP. As described inthe article of Jon Doyle and RichmondThomason about qualitative decision the-ory (AI Magazine, 1999), AI provides qual-itative methods for treating preferencesthat can improve or complement numeri-cal methods for treating preferences fromclassical decision theory. Preferences areessential to treat conflicting informationin nonmonotonic reasoning, reasoningabout action and time, planning, diagno-sis, configuration, and other areas inknowledge representation and reasoning.In constraint programming, preferencesare used to treat soft constraints, and toreduce search effort.
Preferences are complementary toconstraints and represent an AI counter-part to objective or utility functions. AIpermits complex preference representa-tions and thus allows to reason with andabout preferences. Hence, AI provides anew perspective for formalizing informa-tion that is essential for many decisionmaking problems, e.g. web-based configu-ration, scheduling, robot planners.
The purpose of this workshop is toprovide a forum for exchanging experi-ences with different (symbolic) approach-es for treating and applying preferences,for comparing and bridging gaps betweenthese approaches, and for identifyingchallenging questions for future research.It addresses theoretical approaches, algo-rithms, and implemented systems.
Topics■ Preferences in qualitative decision the-
ory, non-monotonic reasoning, AIplanning, reasoning about action andcausality, preference logic
■ Preferences for soft constraints, searchand optimization
■ Preference representations (e.g., graph-ical models)
■ Acquisition and learning of prefer-ences
■ Preference elicitation■ Revision of preferences■ Comparison of approaches■ Applications of preferences
FormatThe workshop will consist of an invitedtalk, technical sessions including paperpresentations and panel discussions, anda final discussion.
AttendanceParticipation is limited to authors of ac-cepted papers and invited researchers in-terested in the topic of preferences (max50 participants). Please send a statementof interest in participation to [email protected].

Preferences in AI and CP: Symbolic Approaches
Recently there has been considerable in-terest in approaches based on randomiza-tion, probability, and uncertainty tospeed up computation and to model re-sources more realistically. For example,the performance and robustness of searchprocedures can often be improved byadding an element of randomness to thesearch procedures, as in randomizedbacktrack search and local search. Fur-thermore, probabilistic methods likeMarkov decision processes, Monte Carlosampling, and Bayesian learning are nowbeing used to study and improve the be-havior of search procedures. The aim ofthis workshop is to explore the use ofprobabilistic methods in the modelingand understanding of search procedures,as well as their role in improving searchprocedures. This is the third workshop inthe series. Previous workshops have beenheld alongside the AAAI-2000 conferenceand within the AAAI-01 Fall Symposium.
Topics■ Modeling uncertainty in computation■ Monte Carlo sampling■ Probabilistic analysis of algorithms■ Ensemble behavior (e.g. phase transi-
tions)■ Randomization and restarts■ Stochastic backtracking■ Stochastic local search■ Portfolios of algorithms■ Anytime algorithms■ Algorithm robustness■ Bayesian tuning of algorithms
FormatThe symposium will consist of invitedtalks, panel discussions, individual pre-sentations and group discussions. Theworkshop will last one full day.

Probabilistic Approaches in Search
While AI methodologies are being ap-plied towards increasingly realistic do-mains that require timely responses, real-time systems are coming to incorporatedecision-making tools that require moreintelligent capabilities. Many real-worldintelligent systems call for autonomousintelligent agents acting in the face of un-certain knowledge and limited computa-tional resources. Real-time decision sup-port and diagnosis systems are two suchimportant application domains.
TopicsActive research topics that are relevant toreal-time decision support and diagnosisinclude:
■ Real-time expert systems■ Embedded intelligent diagnosis agents■ Anytime uncertain reasoning algo-
rithms and flexible computation■ Cost estimation for resource-bounded
computation■ Decision-theoretic planning and delib-
erative real-time artificial intelligence■ Real-time Bayesian network inference
and learning techniques■ Real-time algorithms for scheduling
and situated planning■ Real-time sensor fusion and situation
assessment■ Real-time knowledge discovery in
databases (KDD)
FormatThe one-day workshop will include oneor more invited talks and specialized tu-torials on state-of-the-art research prob-lems and methodologies, presentationsby selected participants, and a panel andopen discussion on key topics.
AttendanceThe workshop will be of interest to re-searchers and practitioners in the area ofuncertain reasoning (UAI), real-time arti-ficial intelligence (RTAI), and real-timeknowledge discovery in databases (KDD).Participation will be based on submitted
research summaries. We anticipate partic-ipation by 25 to 50 people at the work-shop.
SubmissionsPlease submit a brief paper (under 12pages) formatted using standard AAAIguidelines. Experimental results are alsoencouraged, especially on fielded applica-tions, even if they are only preliminary.Papers should be submitted electronicallyin PostScipt or PDF or MS Word formatvia email.

Real Time Decision Support and Diagnosis Systems
This workshop is intended to bring to-gether researchers in AI who are workingon the semantic web and those involvedin the development of standards for lin-guistic annotation, to enable an ex-change of information and ideas. This is acritical point at which to bring togetherthese two groups, who typically have lit-tle interaction. Those involved in devel-oping language resources need to gain adeeper understanding of the potential ofand requirements for the semantic weband standardized ontologies. AI re-searchers, who are working on a generalmodel, will gain insight by consideringan application of their work to actualcontent and, more generally, by consider-ing the needs for a specific domain thatrequires complex representation mecha-nisms and sophisticated means to exploitthe information.
TopicsWe invite short proposals for workshoppresentations, addressing any of the fol-lowing topics:
■ Representing meaning in natural lan-guages using ontological supportand/or practical applications of suchontological-semantic work
■ Problems for representing linguisticdata, including the need to accommo-date potentially different theoreticalapproaches in a common framework,
■ Inadequacies of current means to rep-resent linguistic annotations, and re-quirements for annotation ontologies
■ Potential for exploiting inferencing ca-pabilities etc. in linguistically annotat-ed data, and the representation re-quirements that will enable this
■ Techniques for combining statisticaland non-statistical approaches to on-tology developmentProposals should be approximately 2
pages in length, providing an overview ofthe work to be described. For papers ad-dressing work primarily in the area of on-
tology development or primarily con-cerned with linguistic annotation, a clearstatement of the relevance and/or appli-cability of work in the other domainshould be provided.
The program committee will select 4to 5 proposals for presentation at theworkshop, with the overall goal of assur-ing a balance in the presentation topics.Authors of accepted papers will then beinvited to submit a full paper of approxi-mately 10 pages in length.

Semantic Web Meets Language Resources
This workshop is intended as a forum fordiscussion, exchange of points of view,assessment of results and methods, and asa source of dissemination and promotionof the newest advances in the area of spa-tial and temporal reasoning. Recent yearshave witnessed remarkable advances insome of the longstanding problems of thefield (for instance, new results abouttractability for spatial calculi, explicitconstruction of models, characterizationof important subclasses of relations), aswell as in the development of new areas(the appearance of new integrated spatio-temporal calculi is one example, as wellas the development of multi-dimensionalspatial calculi). Likewise, proposals havebeen made to remedy some of the weakpoints of the symbolic approach, by in-troducing fuzzy versions of classical cal-culi, or importing nonmonotonic tech-niques for dealing with incomplete infor-mation. At the same time, leaders in AIhave sounded the need for solving realproblems and making the work on repre-sentation and reasoning relevant to thereal world.
Around forty participants will be se-lected to attend the workshop, contribut-ing and participating in discussions. Ac-cepted papers will be included in theworkshop working notes to be distributedby AAAI. Screening will be based on re-views and relevance to the workshopgoals.
SubmissionsElectronic submissions are solicited inTeX, LaTeX, PostScript, or PDF format.The papers, starting with title, authors'names, addresses, phone and fax num-bers, and email addresses, followed bykeywords, and concluding with relevantbibliographic references, should fit on 4to 10 single-spaced typewritten A4 or 8.5x 11 inch pages, in the form of an ex-tended abstract or complete research, sur-vey, or position paper. Selection of partic-
ipants will be based on relevance to theindicated focus of the workshop, clarityof the work submitted, and the strengthof the research. Submit to Hans W. Gues-gen
