Ontologies

Domain model

Ontologies used in publication domain (schemata).

  • Region ontology (OWL (16 KiB))
    The region ontology defines basic geographical regions, such as countries, states, cities, streets, currencies and languages.
  • Party ontology (OWL (12 KiB))
    The party ontology defines a party which can be in relation to other concepts.
  • Publication ontology (OWL (20 MiB))
    The publication ontology conceptualizes a publication. See more details here(PDF, 64 KB)
  • Cluster ontology (OWL (8 KiB))
    The cluster ontology describes hierarchically organized clusters of publications from publication ontology.

Ontologies used in publication domain (instances).

We created three ontologies populated by instances containing metadata information gathered from three different sources:

User model

Ontology-based user model defines concepts representing user characteristics and identifies relationships between individual characteristics connected to domain ontology. Such a model is (after its population) used by presentation tools to provide personalized navigation and content. Model can be employed also in content organizing tools (e.g., perform sorting of items based on user's preferences).

User ontology in project MAPEKUS is composed of two standalone ontologies, which separate domain-dependent and general characteristics:

  • Generic user ontology (OWL)
    Defines general user characteristics.
  • Publication user ontology (OWL)
    Defines characteristics bound to the domain of publications represented by domain ontology
