ABSTRACT

The set of relation within a knowledge domain will be expressed with a help of Ontology, but data within the knowledge domain get scattered all over its space. To get a most precise result there must be necessary to relate the concepts or keywords within a domain. One of the efficient ways of matching or relating data must be done by implementing ontology within a domain. It aims to make data sharable. Unfortunately, the ontology is widely distributed as well as heterogeneous. The main aim of Ontology matching is to determine the relationship between the concepts and to find the Semantical mappings between two given ontologies. This problem lies at the heart of numerous information processing applications. In order to dilute the problem evolution of Upper ontology have taken place. The upper ontology will act as a base for representing concepts in all the domains, the primary objective is to extract or representing the general concepts throughout the domains based on the ontological structure.
