**POSCON (Positive Online Content and Services for Children in Europe)
Objective:With more and more children being online at a young age, concepts and ways to accompany and support them in their first and further steps on the internet are needed more than ever. One important keyword here is positive content and services – websites, online content, online environments and increasingly also apps where children can easily and safely enjoy the internet and mobile devices. This issue has been addressed on several levels before – on national level with initiatives bringing forward the production and promotion of positive content, and on European level e.g. with the EC focus group on positive content, the European Award for Positive Online Content, and a session at the Safer Internet Forum dedicated to the topic.
The fact that, during research for this network and before in preparations for Safer Internet Forum, it became obvious that whitelists, browsers for children and in some cases even good websites dedicated to children’s needs are hardly to be found shows that this is a necessary topic to be addressed – by institutions who have experience in producing positive content and services, by researchers who deal with children’s wishes and needs, by parents who want to know where they can send their children online, and by other stakeholder active in the area of positive content.
The aims of the projected thematic network POSCON are to:
a) Exchange good practices, issues and challenges in provision of content to young children, including the business model and make recommendations to enhance production and dissemination of positive content across Europe (including localisation). This activity will include a discussion forum gathering producers and providers in a dialogue on online content for children.
b) Discuss feasibility and requirements of a safe browser for kids / collation of white lists including suggestions on moderation and rating of websites for children. Requirements should take into account accessibility needs of disabled children.
c) Make proposals for the roll over of a European wide competition.
d) Provide a report with overview on the market for positive content for children in Europe.
Participants:Landeszentrale für Medien und Kommunikation Rheinland-Pfalz,(coordinator) (Germany), and several other partners.
Start: November 2012, End:December 2014

REVEAL (REVEALing hidden concepts in Social Media)
Objective: The world of media and communication is currently experiencing enormous disruptions: from one-way communication and word of mouth exchanges, we have moved to bi- or multi directional communication patterns. No longer can selected few (e.g. media organizations and controllers of communication channels) act as gatekeepers, deciding what is communicated to whom and what not. Individuals now have the opportunity to access information directly from primary sources, through a channel we label e'-word of mouth', or what we commonly call 'Social Media'.
A key problem: it takes a lot of effort to distinguish useful information from the 'noise' (e.g. useless or misleading information). Finding relevant information is often tedious. This challenge has become the focus of various research efforts. Many concentrate on the automatic discovery of information by adapting semantic search and retrieval technologies to the particularities of Social Media content. REVEAL, however, aims to discover higher level concepts hidden within information. In Social Media we do not only have bare content; we also have interconnected sources. We have to deal with interactions between them, and we have many indicators about the context within which content is used, and interactions taking place. A core challenge is to decipher interactions of individuals in permanently changing constellations, and do so in real time.This is what we aim for!
We will reveal much more than bare content. Further to discovering what is being said, we will determine how trustworthy that information is. We will predict contributor impact and how much or to what extent all this affects reputation or influence. This allows us to automatically judge the quality and accuracy of content, and bring us to predicting future trends with greater accuracy. We label all this Social Media modalities. The core of our work is to reveal hidden modalities for the benefit of a better understanding and utilization of the Social Media world.

PREPARE (Innovative integrative tools and platforms to be prepared for radiological emergencies and post-accident response in Europe)
Objective:This project aims to close gaps that have been identified in nuclear and radiological preparedness following the first evaluation of the Fukushima disaster. It addresses the call Fission-2010-3.3.1: Update of emergency management and rehabilitation strategies and expertise in Europe.
The consortium intends to review existing operational procedures in dealing with long lasting releases, address the cross border problematic in monitoring and safety of goods and will further develop still missing functionalities in decision support system ranging from improved source term estimation and dispersion modelling to the inclusion of hydrological pathways for European water bodies.
As the management of the Fukushima event in Europe was far from being optimal, we propose to develop means on a scientific and operational basis to improve information collection, information exchange and the evaluation for such types of accidents. This will be achieved through a collaboration of industry, research and governmental organisations in Europe taking into account the networking activities carried out under the NERIS-TP project.
The project will be implemented by the Software & Knowledge Engineering Laboratory (SKEL) in cooperation with the Environmental Research Laboratory (EREL) and the Research Reactor Laboratory (RRL) from the Institute of Nuclear Technology and Radiation Protection (INTRP)
Participants:Karlsruher Institut fuer Technologie (coordinator) (Germany), NCSR "Demokritos" (Greece), and several other partners.

**C2LEARN (Creative Emotional Reasoning Computational Tools Fostering Co-Creativity in Learning Processes)
Objective:The C2Learn project aims to introduce an innovative digital gaming and social networking environment incorporating diverse tools, the use of which can foster co-creativity in learning processes in the context of both formal and informal educational settings.
In developing this project, we are innovating methodologically by introducing two new non-linear thinking processes, as fundamental heuristic devices in assisting the user to generate new types of candidate solutions. These innovations are based on most recent results of cognitive science research, which have marked a breakthrough in our understanding of the roots of reasoning and its relation to emotion and representation: Diagrammatic Reasoning and Emotional Reasoning. We shall also implement these non-linear thinking methodologies in game environments, especially for school age users, in order to enhance the motivational component and to enrich the manner and opportunities of engagement with these activities. In so doing, we shall be guided by an acclaimed educational theory on how to use digital gaming and social networking technology to promote creative thinking in children and the young.
The C2Learn environment will be an open-world “sandbox’’ (non-linear) virtual space enabling learners to freely explore ideas, concepts, and the ‘shared’ knowledge available on the semantic web and the virtual communities in which they participate. In this open-world sandbox, creativity is contextually defined as open-ended, and has no pre-sets or barriers. So too will be the virtual game environment housing nonrestrictive opportunities for learners to engage in creative problem-finding and creative problem solving. These new computational tools – rather than setting a series of preset problems and challenges based on players’ previous actions in the virtual game environment – will afford and generate potential playful experiences surrounding creative problem solving and non-linear thinking tasks.NCSR-D will be the Technical Manager of the project, and will also lead the core technical WP3 “C2Learn Computational Tools”.

**SEMAGROW (Data intensive techniques to boost the real-time performance of global agricultural data infrastructures)
Objective: As the trend to open up data and provide them freely on the Internet intensifies, the opportunities to create added value by combining and cross-indexing heterogeneous data at a large scale increase. To seize these opportunities we need infrastructure that is not only efficient, real-time responsive and scalable but is also flexible and robust enough to welcome data in any schema and form and to transparently relegate and translate queries from a unifying end-point to the multitude of data services that make up the open data cloud.
Transparent relegation and translation relies on detailed and accurate data summaries and other data source annotations, and with increased data volumes and heterogeneity managing these annotations, it becomes by itself a challenging data problem. SemaGrow will (a) develop scalable and robust semantic storage and indexing algorithms that can take advantage of resource naming conventions and other natural groupings of URIs to compress data source annotations about extremely large datasets; (b) develop query decomposition, source selection, and distributed querying methods that take advantage of such algorithms to implement a scalable and robust infrastructure for data service federation; and (c) rigorously test its components and overall architecture over real, complex, interconnected datasets comprising data and document collections, sensor data, and GIS data.
SemaGrow will be rigorously tested on the large-scale and complex agricultural data service ecosystem, comprising more than 20 currently operating data services providing today Gigatriples of RDF data, projected to double before SemaGrow ends and to reach Teratriples by 2020. Being able to query across these datasets is a real and present need in order to, for example, apply financial models to predict crop yield using a combination of historical crop yield data, precipitation forecast models and historical data, live data streams of precipitation sensors, and relevant scientific documentation.
Besides satisfying its current use cases, SemaGrow envisages to develop the scalable, efficient, and robust data services needed to take full advantage of the data-intensive and inter-disciplinary Science of 2020 and to re-shape the way that data analysis techniques are applied to the heterogeneous data cloud.
NSCR-D will serve as the Scientific & Technical Manager and lead two core WPs that will research novel intelligent information management algorithms/methods.
