Corese stands for Conceptual Resource Search Engine. It is a Semantic Web Factory that enables the processing of RDFS, RDF, SPARQL and RDF Rules. KGRAM is a new generic SPARQL 1.1 interpreter that can process labelled graphs in addition to RDF.

QAKiS is a system for open domain Question Answering over linked data. It addresses the problem of question interpretation as a relation-based match, where fragments of the question are matched to binary relations of the triple store, using relational textual patterns automatically collected. There is an online version of the system and a screencast of it too.
Discovery hub is an exploratory search engine which helps you to discover things you might like or be interested in. It widens your cultural and knowledge horizons by revealing and explaining unattended information. Based on Wikipedia data, Discovery Hub is cross-domain and works on numerous topics including music, cinema, literature but also politics, automobile and much more. It allows performing queries in an innovative way and helps you to navigate rich results. As a hub, it proposes redirections to others platforms to make you benefit from your discoveries (Youtube, Deezer and more). There are several recorded demos of Discovery Hub as well as an online public version (old version here).
ZONE-project (and the online demo Reador.NET)
ZONE-project provides a new, innovative way to follow news. At its core, the system is aggregating news items from various RSS feeds. Using the power of semantic web we are able to efficiently tag & annotate each news.Those tags are the basis of filters. Filters allow users to see only news that are relevant.

Semantic Web Import
Semantic Web Import is a plugin allowing the Gephi platform to visualize the semantic RDF graphs. This plugin is made available under the CeCILL-B license. The last version of the plugin can be downnloaded through the Gephi platform. The source code can be found at https://gforge.inria.fr/scm/?group_id=3504. For more details, please contact us.
The Datalift platform brings raw structured data coming from various formats (relational databases, CSV, XML, ...) to semantic data interlinked. Datalift is funded by the French national research agency to develop a platform to publish and interlink datasets on the Web of data. It includes: format transformation, schema mapping, alignment, sparql end-point, access controle and licencing.
Sewese is built upon Corese engine and provides a set of primitives to build interfaces for queries, edition and navigation, and for the management of the transverse functions of a portal (presentation, internationalization, security, etc.). An ontology editor, a generic annotation editor and a basic rule editor are parts of the Sewese platform. The main purpose of Sewese is to integrate recurrent semantic web operations (e.g. perform a SPARQL Query, transform a result binding in a given view) in classic web technologies (e.g. JSP pages, servlet calls).

We provide GRDDL RDFa profiles for GRDDL source documents using the latest GRDDL RDFa transform. These profiles and the associated transformations are available as freeware and under the non viral open-source licence CeCILL-C. We also maintain a lightweight RDFa Parser in Java.
Web page extractor
We provide a simple web page text and metadata extractor API in Java as an JAR Archive (v1.2) with its Documentation and Sources. It requires Apache Lang library. It is available as freeware and under the non viral open-source licence CeCILL-C.
ECCO is a contextual and collaborative ontology editor. It allows people with different profile to work together on ontology creation. External NLP tools are integrated into the editor in order to allow users to extract significant terms from domain texts while a vocabulary is being created. Graphical tree views are provided to create a hierarchy from a vocabulary by drag'n'drop. The editor is available as freeware and under the non viral open-source licence CeCILL-C.
