IST NeOn-project.org Next Generation Semantic Web Applications NG SW ApplicationSemantic WebSmart Features  Able to exploit the SW at large –Dynamically retrieving the relevant semantic resources –Combining several, heterogeneous Ontologies  Need tools and infrastructures to efficiently access the knowledge available on the SW: a Gateway…

IST NeOn-project.org A Gateway to the Semantic Web

IST NeOn-project.org Watson Architecture Keyword Search SPARQL Query Crawling Parsing (Jena) Validation/ Analysis Indexing RepositoryURLsMetadataIndexes populates used extracted retrieved Ontology Exploration queries request WWWWWW discovered CollectingAnalyzing Querying

IST NeOn-project.org Collecting 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.

IST NeOn-project.org Analyzing Semantic Content  Have to deal with Heterogeneity! Great variety in… Size Coverage Richness Etc.

IST NeOn-project.org Interfaces, Demos and Applications… Interfaces: WUI Web User Interface:

IST NeOn-project.org Web services and API Watson Server Semantic repository Metadata repository Indexes Ontology Search Service Entity Search Service Semantic Web Application Watson API SOAP Allows applications developers to access Watson features, and so the collected knowledge, in a lightweight way. But what applications (can) do with it?

IST NeOn-project.org Applications PowerAqua: Question Answering PowerMagpie: Semantic Browsing Folksonomy Enrichment Protégé and NeOn Toolkit plugin: Knowledge reuse Ontology Matching, etc…

IST NeOn-project.org

IST NeOn-project.org

IST NeOn-project.org Final 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!
