Approach to the creation of terminological ontologies

The technique for creating networks of natural hierarchies of terms based on the analysis of chosen sets of texts on selected issues is offered. The network is formed automatically on the basis of the teaching collection of texts and can be considered as the basis for the design of terminological ontologies. The technique is based on the methodology of horizontal visibility graphs for individual words, bigrams and trigrams, as well as establishing links between the terms. The network of natural hierarchies of terms covers connection "general-private" type and can be considered as a basis of creation of networks with associative links. Designed and investigated language network, formed on the basis of full texts of popular scientific papers is reviewed. Use of HITS algorithm for this network is proposed. The named algorithm makes the choice of the best "authors" - nodes that have the most citations, and "intermediaries" - nodes that establish the biggest number of citation links is offered.
