The consortium comprises expertise in Semantic Web technologies, ontological engineering, machine learning, Web search, information retrieval, databases and knowledge stores. With CWI’s reputation in the database world, LOD2 aims to substantially contribute to cross-fertilization between database and semantic web research. The LOD2 consortium has engineering power provided by TenForce, Exalead and OpenLink Software as well as dissemination and exploitation expertise provided by its innovative SMEs (Exalead, Openlink, TenForce and SWC), a large corporation (WKD) and the eGovernment and Open Knowledge communities represented in the consortium by OKFN. Within efforts such as the Linking Open Data effort, DBpedia and MonetDB (and numerous smaller community and open-source projects), the project partners demonstrated that they can achieve high-impact results.

LOD2 Partner

Centrum Wiskunde & Informatica

CWI will be primarily involved in WP2 and work together with OpenLink on improving RDF data management with state-of-the-art database research approaches. CWI will be involved with a minor stake in WP5 in order to evaluate and adapt browsing and navigation in large-scale knowledge bases.


Exalead will contribute and advance components of its search engine infrastructure, with emphasis on semantic linked data and search on linked data. Exalead search technology will be adapted and integrated as a component in the LOD2 Stack. An open search API will be developed to browse and access to the semantic linked data. As an (application) service provider in corporate environments, Exalead will lead the specification, setup and implementation of the enterprise use case (WP8). In addition to this, Exalead will provide a prominent channel for exploiting this use case and the outcomes of the LOD2 project as a whole.

Zemanta d.o.o.

Zemanta builds a contextual engine that takes text, analyzes it, and finds related content that compliments the original text (images, related stories, links and tags). The engine is built around contextual analysis and semantics, runs in real time, and is quite scalable. Zemanta was founded in 2007 and in March 2008 launched a service for bloggers. It now serves 100.000 monthly active bloggers. Zemanta developed additional services for professional media, an API for third party developers, and a contextual service for email (gMail and Yahoo Mail).
