- .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
Challenges with ontologies
- ontologies describe the data on a Web
- very good suited as a knowledge base, e.g. medical history, interworking of medicine, oil drilling
- when using a semantic model in the real world, the challenge is to get changes (updates) to the ontologies. Example: car industry, where cars are produced under the same header with slightly different outfit, where manufacturers change frequently,...
Summary on Ontologies
- cover only limited area (specific area, "swamps of ontologies")
- have a "creation date" (timestamp) in mind
- consistency when upgrading one ontology
- are good for knowledge management
- interface between knowledge management and processes is not clear
