Verification of knowledge shared across design and manufacture using a foundation ontology

Seamless computer-based knowledge sharing between departments of a manufacturing enterprise is useful in preventing unnecessary design revisions. A lack of interoperability between independently developed knowledge bases, however, is a major impediment in the development of a seamless knowledge-sharing system. Interoperability, being an ability to overcome semantic and syntactic differences during computer-based knowledge sharing, can be enhanced through the use of foundation ontologies. Foundation or core ontologies can be used to overcome differences existing in more specialised ontologies and to ensure seamless knowledge sharing. This is because these ontologies provide a common grounding for domain ontologies to be used by different functions or departments. This common base can be used by mediation and knowledge verification systems to authenticate the meaning of knowledge understood across different domains. For this reason, this research proposes a knowledge verification framework for developing a system capable of verifying knowledge between those domain ontologies which are developed out of a common core or foundation ontology. This framework makes use of ontology logic to standardise the way concepts from a foundation and core concepts ontology are used in domain ontologies and then, by using the same principles, the knowledge being shared is verified.
