National Initiatives


The ISICIL ANR project had its mid-term review in June 2010 and was positively evaluated. ISICIL proposes to study and to experiment with the usage of new tools for assisting corporate intelligence tasks. These tools rely on web 2.0 advanced interfaces (blog, wiki, social bookmarking) for interactions and on semantic web technologies for interoperability and information processing.

As part of a paradigm of social epistemology, the project combines in an ergonomic approach, an impregnation of ground truth data, a bibliometric study and technological inspiration to offer schemas and inferences exploiting the semantic web and social networks to assist the Corporate intelligence. Initially, three core modules have been developed (tag management service, users' profiles service and a service coupling scraping and semantic wiki) to validate the architecture.

For the tag server, Edelweiss designed a semi-automatic method for semantic structuring of folksonomies: we compared and selected thirty distances for calculating the spelling variations that we combined with usage metrics (co-utilization, inclusion of communities). The use of SKOS (description thesaurus), SIOC and SCOT (for tags) to model the outcome of the analysis was extended by new ontologies published and open-source (SRTag and NiceTag) that support semantic contradictions between users.

For the profile server we designed schemas and algorithms for a series of operators for the semantic analysis of social networks. We signed a research agreement with the social network Ipernity that allowed us to test the algorithms on a network of 60,000 members and 500,000 relations typed in RDF. A first version of the model used for the representation of communities has been tested as well as several SPARQL formalizations for the calculation centrality parameterized by an ontology. A full test campaign is underway as well as a new work on the identification of communities.

Two Master Thesis have been performed [38] , [39] . Deliverables: [36] , [33] , [34] . Web site: .


The DataLift ANR project started in September 2010 for three years. DataLift is a research project funded by the French national research agency. Its goal is to develop a platform to publish and interlink datasets on the Web of data. DataLift will both publish datasets coming from a network of partners and data providers and propose a set of tools for easing the datasets publication process. See .


The Kolflow ANR project was accepted in 2010 and will start beginning of 2011 for three years. Kolflow aims at building a social semantic space where humans collaborate with smart agents in order to produce knowledge understandable by humans and machines. Humans are able to understand the actions of smart agents. Smart agents are able to understand actions of humans. Kolflow targets the co-evolution of content and knowledge as the result of interactions of humans and machines.
