Collecting and Analyzing KnowledgeCollecting and Analyzing Knowledge

• Hundreds of thousands of semantic documents.

• Millions of RDF entities, most of them being instances.

• New sources of knowledge are frequently integrated (DBPedia, geoname, etc.)

Web services and APIWeb services and API

• Allows applications developers to access Watson features, and so the collected knowledge, in a lightweight way.

• But what applications (can) do with it?

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

To be continuedTo 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
