    UMBEL Semantic Web Services - Presentation Transcript

    1. April 2008 Upper Mapping and Binding Exchange Layer UMBEL’s Eleven: Initial Semantic Web Services
    2. UMBEL is . . .
      • . . . a lightweight reference structure for placing Web content and data in context with other data.
      • . . . is comprised of about 21,000 subject concepts and their relationships — with one another and with external vocabularies and named entities .
    3. Subject Concepts
      • 21,000 defined reference points in information space
      • Means to assert what a given chunk of content is about
      • Enable similar content to be aggregated
      • Place content in context with other content
      • Aggregation points for tying in named entities
      • Totally derived and a subset of OpenCyc, the open source version of the Cyc knowledge base
      http://www.opencyc.com http ://www.cycorp.com
    4. Deriving from OpenCyc
    5. Named Entities
      • The places , events , people , objects , and specific things of the real world
      • Literally millions of notable instances
      • Each belongs to one or more subject concept(s)
      • Currently, the predominate basis for Linked Data
      • Important sources include Wikipedia (Yago) and other public sources
      • Can be readily mixed-and-matched with private entities
    6. UMBEL is Middleware
      • UMBEL ontology is based on RDF
        • RDF Schema vocabulary of SKOS (Simple Knowledge Organization System)
        • OWL Full to aid class, domain and range relationships with external ontologies
        • Provides excellent interoperability
      Any external content (ontologies + named entities) Any external content (ontologies + named entities)   UMBEL  OpenCyc (inferencing, structure and other tools)
    7. UMBEL is a Roadmap
      • A set of roadsigns to help find related content
      • A contextual way to get from one concept space to another
      • More detailed maps used for specific domains
    8. UMBEL is a Backbone
      • The backbone to UMBEL is the relationships amongst its subject concepts
      • The backbone provides the contextual graph for inter-relating content
      • The backbone is a reference structure for more specific domains or ontologies
      • The backbone is contextual , and relatively stable and constant
    9. Exploding the Domain
      • Each subject concept is an individual of the skos:Concept class, which are themselves OWL classes
      • Since subject concepts are classes, can relate to external ontology classes using rdfs:subClassOf and owl:equivalentClass
      • Under right circumstances, can also inherit properties
      • Through inferencing, silo data now can inherit open world understanding, therefore:
      •  exploding the domain
    10. A Deep Dive into the Backbone . . . . . . all 21,000 nodes
    11. A Deep Dive into the Backbone . . . . . . top 750 nodes
    12. A Deep Dive into the Backbone . . . . . . top 350 nodes
    13. A Deep Dive into the Backbone . . . . . . zeroing in on ‘automobiles’
    14. A Deep Dive into the Backbone . . . . . . zeroing in on ‘Saabs’
    15. The First Eleven Web Services
    16. UMBEL’s Eleven
      • Find Subject Concepts

      • List Sub-Concepts & Sub-Classes
      • List Super-Concepts & Super-Classes
      • List Equivalent External Classes
      • Verify Sub-Class Relationship
      • Verify Super-Class Relationship
      • Verify Equivalent Class Relationship
      • Subject Concepts Explorer

    17. Demos, Docs & APIs
    18. Find Subject Concept
    19. Subject Concept Detailed Report
    20. Subject Concept Explorer
    21. YAGO Ontology
    22. Why Important to the Semantic Web?
      • Context, Context, CONTEXT
      • For Linked Data
        • Context !
      • For Web Search:
        • Infinite facets
        • Disambiguation
        • Cleaner navigation
      • For Legacy Data Stovepipes:
        • Making the connections
        • Closed World schemas become Open World information
        • Context !
    23. Play for Yourself
