12. IST-2005-027595 NeOn-project.org Watson NeOn Toolkit plugin  While building an ontology with the Neon toolkit  Find descriptions of existing entities in Web ontologies  Integrate these descriptions into the edited ontology  Thus allowing knowledge reuse at the scale of the Semantic Web  In one simple, integrated, and interactive tool

13. IST-2005-027595 NeOn-project.org To be continued  Both the Watson plugin and Watson in general are ongoing work  Current work in many areas related to NeOn activities –Detecting and managing relations between ontologies (equivalences, versions, compatibility, etc.) –Combining automatic evaluation, user evaluation and trust for (customized) ontology ranking –Exchange with the Oyster peer network (the NeOn registry) and the alignment server –From reusing knowledge to creating networks of ontologies
