      • Service-level discovery metadata
      • Provenance tracking / SAF integration
      • Web browser plugins
benefits of semantics
Benefits of Semantics
  • Claim: S2S leverages semantics to provide a metadata vocabulary, and, in future versions, will use linked data practices for dereferenceable framework metadata.
benefit of semantics1
Benefit of Semantics
  • Claim: S2S provides explicit semantics for the relationships between web services, search parameters, and user interface widgets.
benefit of semantics3
Benefit of Semantics
  • Claim: S2S leverages RDFS reasoning to infer sub-class transitivity for type checking, and, in future versions, will use OWL-DL to perform instance integrity checking using cardinality and value qualifiers.
benefit of semantics4
Benefit of Semantics
  • For integrity checking…
    • …In component registration/validation
      • OpenSearchServicehasDescriptionDocumentexactly 1 xsd:anyURI
      • WidgethasGeneratorFunctionexactly 1 xsd:string
    • …In real-time user interface building
      • HierarchicalWidgetforWidgetonly OrdinalParameter
  • For sub-class reasoning…
    • …To answer queries like “select all widgets” when many widgets are not directly classified as type s2s:Widget

questions from class
Questions from Class
  • Jin: See slides 8, 10, and 12
  • Peter:
    • Claim 1: Vocabulary and metadata are not Semantic Web terms. For an explanation of linked data see: http://bit.ly/PmwsA
    • Claim 2: Semantics is also not a Semantic Web term. Basically, I provide a directed graph where the vertices denote concepts and the arcs denote relationships between concepts in the framework. See: http://bit.ly/ebKcRV
    • Claim 3: See slide 12
questions from class1
Questions from Class
  • Scott: S2S uses only lightweight semantics. Basically:
    • Structured metadata
    • Explicit semantics
    • Automated integrity checking
    • …propose alternative solution for reusable user interface and a federated search platform that spans web service standards?
  • Ping: Swoogle searches for ontologies, S2S is a search platform. Yes, I created the metadata.
