Abstract. The author develops а method for automatic generation of ontological knowledge bases. An algorithm for extraction of explicit semantic relationships between concepts of ontology on the basis of their semantic-syntactic valence vectors has been developed. Vectors of semantic-syntactic valences of words have been also used as context vectors for formal concept analysis algorithm, which has allowed us to develop the method of automatic generation of high-quality taxonomies. A basic algorithm for automatic construction of ontological knowledge bases has been developed on the basis of the tensor semantic-syntactic model of natural language.

Keywords: automatic extraction of knowledge, corpus linguistics, ontologies, non-negative tensor factorization.
