Semantic Comparison of Ontologies Based on WordNet

The increasing use of ontologies in recent years has led to much of the information represented in them appear in differently expressed ways. When integration processes of ontologies are required within the same domain, problems arise in the correspondence between the terms that appear in ontologies involved in the process. To solve this problem, this article presents a method, which provides the user with a value of similarity between the terms of two ontologies to assist in the integration process. The method is based on the use of the lexical database defined by WordNet and the application of semantic similarity algorithms. It also introduces a software tool that carries out the implementation of this method.
