2. ScienceWise – JRA1 A web-based scientific platform to boost research • 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 Goal:Develop a participatory platform towards 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 http://sciencewise.info

3. CloudSpaces –JRA5 Open Service Platform for the Next 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 http://cloudspaces.eu

4. Reconcile – JRA5 Robust Online Credibility Evaluation of Web Content • Motivation: • Internet has become the primary source of information • Misleading, questionable and factually incorrect Web pages • Serious consequences for decision-making in critical domains Goal:Creation of new mechanisms for supporting users in the evaluation of Web content credibility. • 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/) Machine learning based credibility assessment • Use cases: • Credible Web search • Online medical information credibility evaluation • Credibility control in an open shared knowledge base (http://sciencewise.info) Snapshot of Reconcile credibility evaluation system prototype http://reconcile.pjwstk.edu.pl/

5. Wattalyst –JRA8 Modelling and Analysing Demand Response (DR) Systems • 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 http://wattalyst.org
