  1. From… …to Ontology Repositories Mathieu d’Aquin Knowledge Media Institute, The Open University m.daquin@open.ac.uk

  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

  3. Finding Ontologies: Why? Because there are lots of them!

  4. Gateway is a Search Engine for the Semantic Web

  5. Architecture

  6. Web Interface

  7. Web Interface Advanced Keyword Search

  8. Web Interface Ontology Exploration

  9. Web Interface Ontology Metadata

  10. Web Interface Querying

  11. 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

  12. Next Generation Semantic Web Applications

  13. Natural language question Answers from online semantic data Example Application:PowerAqua

  14. Chose an entity to search Integrate statements Into the edited ontology Get entities from online ontologies Example Application:The Watson Plugin

  15. But… But Watson is a Semantic Web search engine, not an Ontology Repository…

  16. From a Semantic Web search engine…

  17. Comments and Reviews Ontology Metadata Alignments Versions of … to Ontology Repositories? Ontologies

  20. 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.
