Collecting and Analyzing KnowledgeCollecting and Analyzing Knowledge
• Specialized crawlers for ontology repositories and semantic relations. • Watson has collected tens of thousands of semantic documents. • This represents Millions of RDF entities, most of them being instances.
• New sources of knowledge are frequently integrated (FOAF, DBPedia, etc.), so that this number is growing rapidly.

• Allows applications developers to access Watson features, and so the collected knowledge, in a lightweight way.
• But what applications (can) do with it?

Final MessageFinal Message
Watson is an ongoing project to build a Gateway to the Semantic Web
Usable Now!
But lost of directions for improvements
So…
Use it! Show it! Torture it!
Build new applications with it!And…
Send feedbacks! Suggest new features!
Suggest new applications!
