Usage of Domain Ontologies for Web Search

The Web is a wide repository of information available, but its heterogeneity, size and human oriented semantic supposes an obstacle in the search for desired information. Web search engines are a great help for accessing Web resources, nevertheless their classification algorithms are still limited since they only check the presence of a specific keyword or links, they do not analyse the semantic content of the resources. In recent years, several works are being related to convert the Web from an information space to a knowledge space by using common plans. One of the ways to achieve this purpose is the use of ontologies. The present paper proposes a methodology, where previously defined domain ontologies and the WordNet thesaurus are used to perform semantic searches obtaining suitable Web page results that really belong to the expected domain.
