    2. 2. Finding Ontologies: Why? <ul><li>For reuse </li></ul><ul><ul><li>To build upon what exists </li></ul></ul><ul><ul><li>To adopt what is used in practice </li></ul></ul><ul><ul><li>Not to re-invent the wheel </li></ul></ul><ul><ul><li>Because it is simpler than building from scratch </li></ul></ul><ul><li>For applications </li></ul><ul><ul><li>Because semantic applications need knowledge </li></ul></ul><ul><ul><li>Because knowledge is hard to acquire </li></ul></ul><ul><ul><li>Because some scenarios require to gather this knowledge at run-time </li></ul></ul><ul><ul><li>Because in some scenarios, the more there is, the better </li></ul></ul>
    3. 3. Finding Ontologies: Why? Because there are lots of them!
    4. 4. is a Search Engine for the Semantic Web Gateway
    5. 5. Architecture
    6. 6. Web Interface
    7. 7. Web Interface Advanced Keyword Search
    8. 8. Web Interface Ontology Exploration
    9. 9. Web Interface Ontology Metadata
    10. 10. Web Interface Querying
    11. 11. APIs <ul><li>SOAP and REST APIs that provide the infrastructure to: </li></ul><ul><ul><li>F ind SW documents and retrieve metadata about them </li></ul></ul><ul><ul><li>Find entities (classes, properties, individuals) and explore their semantic description </li></ul></ul><ul><ul><li>Apply SPARQL queries to Semantic Web documents </li></ul></ul>
    12. 12. Next Generation Semantic Web Applications
    13. 13. Example Application: PowerAqua Natural language question Answers from online semantic data
    14. 14. Example Application: The Watson Plugin Chose an entity to search Get entities from online ontologies Integrate statements Into the edited ontology
    15. 15. But… But Watson is a Semantic Web search engine, not an Ontology Repository…

    17. 17. … to Ontology Repositories? Ontologies Ontology Metadata Versions of Alignments Comments and Reviews
    18. 18. The future of Watson: Ontology submissions Mapping submissions Ontology metadata Ontology rating Trust statements Watson Engine Open Rating System Alignment Server Cupboard Interface APIs and GUIs for search, querying, exploration, etc.
    19. 19. Exchanging information about ontologies The future of Watson: Watson Engine Open Rating System Alignment Server Cupboard Interface APIs and GUIs for search, querying, exploration, etc. Watson Engine Open Rating System Alignment Server Cupboard Interface APIs and GUIs for search, querying, exploration, etc. Watson Engine Open Rating System Alignment Server Cupboard Interface APIs and GUIs for search, querying, exploration, etc. Watson Engine Open Rating System Alignment Server Cupboard Interface APIs and GUIs for search, querying, exploration, etc. … Cupboard in KMi Cupboard in Karlsruhe Cupboard in Madrid Cupboard in W3C
    20. 20. So, to conclude… <ul><li>Watson is a powerful engine to index semantic content (ontologies) and build applications taking benefit from this content. </li></ul><ul><li>It provides the basic functionalities to build an ontology repository with active, dynamic user contributions in various forms. </li></ul><ul><li>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… </li></ul><ul><li>A decentralized network for sharing, distributing, discussing and making use of ontologies. </li></ul>
