Víctor Penela Guillermo Álvaro Rey Carlos Ruiz Carmen Córdoba Francesco Carbone Michelangelo Castagnone José Manuel Gómez-Pérez Jesús Contreras miKrow: Semantic Intra-Enterprise Micro-Knowledge Management System June 1st, 2011 | Heraklion, Greece 8th Extended Semantic Web Conference (ESWC 2011)
  • 2. Agenda
    • The miKrow concept
    • The miKrow approach
      • Semantic Indexing
      • Semantic Search
    • miKrow enrichments
      • Linked Data consumption
      • ACTIVated miKrow
      • Contextual miKrow
      • User collaboration and feedback
    • Evaluation / Summary
  • 3. miKrow: Micro-Knowledge Management In a nutshell… Semantic Intra-Enterprise Micro-Knowledge Management System
  • 4. Collaboration Interoperability and Access to Information Semantic Web Web 3.0 Enterprise 3.0 Web 1.0 - - + + Enterprise 3.0: Collaborative aspects of Web 2.0 + Semantic Technologies applied to the enterprise Web 2.0 Enterprise 2.0
  • 5. Agenda
    • The miKrow concept
    • The miKrow approach
      • Semantic Indexing
      • Semantic Search
    • miKrow enrichments
      • Linked Data consumption
      • ACTIVated miKrow
      • Contextual miKrow
      • User collaboration and feedback
    • Evaluation / Summary
  • 6. The miKrow approach We take something existing Microblogging Engine + Semantic Engine We add value here
  • 7. Microblogging engine: Jaiku Runs on Google App Engine
  • 8. Semantic engine Via REST API Supported by domain ontologies Using a semantic index
  • 9. Semantic Indexing and Search Performed for every micropost messages + experts
  • 10. Message Indexing
  • 11. Expert Indexing
  • 12. Message Search
    • Morphological variations and ortographic corrections
    • Mapping to ontology terms + thesauri
    • Close terms in the ontology
    • Expanded query with original terms and (weighted) related terms
    Query built from user input by:
  • 13. Expert Search
  • 14. In Use… Before posting
  • 15. In Use… Related messages New suggestions stream Related experts Terms found
  • 16. Agenda
    • The miKrow concept
    • The miKrow approach
      • Semantic Indexing
      • Semantic Search
    • miKrow enrichments
      • Linked Data consumption
      • ACTIVated miKrow
      • Contextual miKrow
      • User collaboration and feedback
    • Evaluation / Summary
  • 17. Enriching the basic prototype
    • Linked Data consumption
    • ACTIVated miKrow
    • Contextual miKrow
    • User Collaboration and Feedback
  • 18. Linked Data consumption Linking Open Data cloud diagram by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/ Entity recognition It helps keeping knowledge base up to date…
  • 19. Using a external service Consuming Linked Data
  • 20. In Use… Linked Data Entity Recognition
  • 21. ACTIVated miKrow It helps tackling the cold-start problem…
    • Working Context
    • Resource
    • Knowledge Process
  • 22. ACTIVating miKrow Using a external service
  • 23. In Use… Related working contexts, processes and resources…
  • 24. In Use… … connected to the ACTIVE system
  • 25. Contextual miKrow Context data (e.g., location) Improving the index with contextual information
  • 26. miKrow in context Using a external service
  • 27. In Use… Location used as contextual information
  • 28. User (I): Collaboration Spheres Future Work! Finding the ad-hoc relationships within the system (Result from )
  • 29. (Result from ) User (II): Feedback Future Work! Leveraging User Feedback to improve the suggestions Ratings in a semantic format through API with LUF
  • 30. Agenda
    • The miKrow concept
    • The miKrow approach
      • Semantic Indexing
      • Semantic Search
    • miKrow enrichments
      • Linked Data consumption
      • ACTIVated miKrow
      • Contextual miKrow
      • User collaboration and feedback
    • Evaluation / Summary
  • 31. Evaluation
    • In-house (iSOCO, SME ~100 people, 4 locations)
    • ACTIVated version (dummy ontology and examples)
    • Microblogging has its own rules and syntax (no straight reuse of a knowledge model)
    • Microposts may have temporal relevance
    • User feedback to be considered
    • Explanations are important (show intelligence )
  • 32. Summary
    • miKrow = microblogging + KM
    • Intra-Enterprise (domain ontology)
    • Semantic index, ontology + thesauri queries
    • Simple approach + Extensions
    • Two prototypes
    • Future work: User Collaboration and Feedback
    Easy to use Semantically powered
