Goal: Develop a participatory platformtowards the conceptualization of scientific knowledge and its large scale analysis.

Achievements: Developed a web-based system already used by many scientists for semantically importing, storing

and searching scientific data. Obtained a crowdsourced ontology with over 15K concepts for physics and life science

Motivation: The volume of research information outgrows our individual capacity to process it Publications and knowledge are scattered across different sources Scientific achievements rely on multiple disciplines

CloudSpaces –JRA5Open Service Platform for theNext Generation of Personal Clouds Easily usable privacy enhancing tools for end-users. Also allow users to transparently access data stored at multiple cloud services Allow small datacenters to share their resources to meet user demand

For privacy, we have proposed a novel framework that relies not just on content but also the context or semantics of data sharing

We base our framework on psychologically grounded models in order to determine privacy preferences

We use Crowdsourcing for determining sensitivity of sharing operations

Our software provides policy recommendations to users in order to share their files safely on any cloud platform

Motivation: Internet has become the primary source of information Misleading, questionable and factually incorrect Web pages Serious consequences for decision-making in critical domains

Achievements: Novel Web credibility evaluation mechanisms

by leveraging crowdsourcing, big data analytics, machine learning, etc.

Game theoretic models for robust credibility evaluation.

A unique large-scale credibility corpus Web credibility evaluation prototype system

(http://www.reconcile.pl/)

Use cases: Credible Web search Online medical information credibility

evaluation Credibility control in an open shared

knowledge base (http://sciencewise.info)

Goal: Creation of new mechanisms for supporting users in the evaluation of Web content credibility.

Machine learning based credibility assessment

Providing incentives to consumers to alter their behaviour and ensure energy balance Observing energy consumption data to infer patterns and measure the influence of DR

on energy consumption

Approach: Energy consumption disaggregation,

prediction and segmentation using statistical machine learning methods

Game-theoretic, economic and behavioural models of energy consumers

Field trials with residential and commercial consumers

Results: Design guidelines for effective

incentives to change energy consumption patterns

Tools and algorithms for energy data analytics
