Slide 2

Finding Ontologies: Why?

• For reuse – To build upon what exists– To adopt what is used in practice– Not to re-invent the wheel– Because it is simpler than building from scratch

• For applications – Because semantic applications need knowledge– Because knowledge is hard to acquire– Because some scenarios require to gather this

knowledge at run-time– Because in some scenarios, the more there is, the

better

APIs

• SOAP and REST APIs that provide the infrastructure to:– Find SW documents and

retrieve metadata about them

– Find entities (classes, properties, individuals) and explore their semantic description

– Apply SPARQL queries to Semantic Web documents

So, to conclude…

• Watson is a powerful engine to index semantic content (ontologies) and build applications taking benefit from this content.

• It provides the basic functionalities to build an ontology repository with active, dynamic user contributions in various forms.

• But more than that, a decentralized multi repository made of user’s ontology spaces and that institutions can adopt and connect through a peer-to-peer architecture…

• A decentralized network for sharing, distributing, discussing and making use of ontologies.
