The purpose of the article is the development of mathematical methods of formalizing the collocation in the texts. This can help to improve the quality of search and clustering text collections, through the introduction of collocations in the vector space model, considering the distance between terms. In the research are used theories of fuzzy sets, information retrieval and matrices. Researches, given in this article, are not answer at such questions as how to use this collocation for informational retrieval or text clustering, moreover all given researches are limited by a consideration of collocation as a pair of terms. Method of formalization of the collocation, which considering the distance between terms using the theory of fuzzy sets, is offered. This method consists in the formalization of the distance between terms by means of linguistic variable. Moreover, in the article enhanced vector space model of the text collection is offered, which give us a tool to conduct comparative analysis of using terms and fuzzy collocations for informational retrieval.
