Abstract: The invention relates to the structure of an upper ontology and a system and method for utilizing an upper ontology in the creation of one or more multi-relational ontologies. The invention includes an upper ontology of predefined concept and relationship types, and a predefined set or relationships that may be used to connect particular pairs of concepts. The concept and relationship types may be dictated by the knowledge domains in which the resultant ontology is to reside. The invention may also include a hierarchy of concept types wherein the relationships that may exist between concept types is specified.

Abstract: The invention relates to a system and method for knowledge capture using multi-relational ontologies. The system may enable an ontology service provider to ascertain the scope of an entity's knowledge capture needs, create one or more base ontologies from publicly available sources, and incorporate the entity's private data into one or more value-added custom ontologies.
