Mapping Heterogeneous Ontologies through Ontology Algebra View

Ontology provides a shared and reusable piece of knowledge about a specific domain, and has been applied in many fields, such as Semantic Web, e- commerce and information retrieval, etc. The semantic web technologies, especially Ontologies, pave the way to enhance Knowledge Management (KM) solutions that are based on semantically related pieces of knowledge. Although the semantic web base KM approaches and solutions have shown the benefits of Ontologies and related method, there are many open research issues and problems that have to be addressed in order to make semantic web technologies fully effective when applied to KM solutions. However, building ontology by hand is a very hard and error-prone task. It is believed that the ontology engineering will be a major effort of any future application development. In this paper we describe new methodology for mapping heterogeneous ontologies using ontology algebra and both intermediate and transmit ontology as far as possible between hierarchy of ontologies. This solution has high quality for mapping heterogeneous ontologies when compared with other methodologies.
