The research tools of text collections on the basis of graph-theoretic models in information system «Folklore»

The article describes analysis tools of text collec¬tions on the basis of graph-theoretic models, imple¬mented in information system «Folklore». With the help of these tools, input, storage, editing, visualiza¬tion, aggregation and comparative analysis of texts and their graph-theoretic models are realized. These methods can be used to solve the problems of genre differentiation and attribution of texts, compiling of the¬matic indexes, abstracting and information retrieval.
