Abstract: The method of automatic ontology integration on the level of alignment has been developed. The thesaurus, which is result of integration, is used for translation queries in term of particular ontologies. It makes possible to carry out semantic search in heterogeneous informational recourses, which are presented by different ontologies. The procedure of adding of terms of new ontology has been presented. It also contains analysis of semantic equivalence of a new terms and terms, which already have been added. As the result of this analysis, the weighted relations are formed.

Keywords: ontology, semantic search, ontology integration, thesaurus, algorithm.
