Semantics

previous lecture

  • .xml relation between subject & object
  • .rdf subject, predict, object
  • .rdfs vocabulary for properties
  • ontologies as data models of a domain
    • describe through rdf or owl
    • owl is more expressive
  • Extension of semantics through rules
  • Rules might replace ontologies
