The AlignmentOntology

The AlignmentOntology aims for a formalisation of the concept of an alignment and the relations it is based on. It is defined by an RDFSchema file, available in the repository. A corresponding Protégé project is also available. Be aware that this ontology is under development and may be subject to changes.

News

  • [29.06.06] The AlignmentOntology has been created by Benjamin Horak and Björn Endres. The draft is now subject to discussion.

Ontology Description

The AlignmentOntology basically defines relations between ontology entities, e.g. classes, properties, instances. The semantic of a basic, untyped relation is a connection of any kind, a cooccurrence. There are also further specifications of a realtion:

  • Subsumption defines a relation like subclass_of or subproperty_of
  • Superordination is the opposite of Subsumption
  • Equivalence defines the two entities as semantically equivalent. In particular, this is the case if it is a supsumtion AND a superordination at the same time.
  • Classification defines a type_of relationship, e.g. that an instance belongs to a class.
  • Distinction states, that neither of the above holds for the relation

Each relation defines

  • the two entities to relate
  • a confidence value which expresses the confidence that the producer has of the correctness of the relation
  • an arbitrary number of attachments, that supply additional information but are formally not important.

Finally, an Alignment is defined as a set of such Relations. Since the consistency of an alignment is controversial, this is not taken care of here. Further specialisations of Alignment will adress such issues.
