The article analyzes automated construction technologies of the semantic network of subject field terms. The advantages of using semantic networks in automatic text processing problems are presented. It is proposed to use the terminological vocabulary of the subject domain as the initial information for building a semantic network. The method of calculating the strength of semantic links between terms of the domain is analyzed and software is developed for the application of the method. It is shown that the method of automated construction of a semantic network of terms can be used in designing ontologies when creating corporate knowledge bases (pp.75-82).
