An Analysis of Some Relations Among Domain Ontologies

* This paper was made according to the program of fundamental scientific research of the Presidium of the Russian Academy of Sciences «Mathematical simulation and intellectual systems», the project "Theoretical foundation of the intellectual systems based on ontologies for intellectual support of scientific researches".

Building domain ontologies and applying them to different objectives, researchers faced the fact that many ontologies are associated with one another by one or another relations. Therefore, the problem arose to study relations among different ontologies of the same domains as well as of different ones. A formalization of a relation among domain ontologies is the analogous mathematical relation among mathematical models of these ontologies. The article considers the case when domain ontology model is represented by logical relationship system. Relations among domain ontologies give a possibility to reuse one ontology model when another ontology models are worked out and when new intellectual computer system for same or different domain is worked out.
