Lexical pairs analysis for automatic generation of dialogue and monologue speech

In the paper the sub-problem of the problem of correct and meaningful text formation by means of software application, and namely the problem of formal presentation of association transfers between sentences and natural language texts fragments is considered. The main idea in solving the sub-problem is to formalize and estimate the distance between natural language word pairs as pairs of vectors of multidimensional semantic space of natural language words. The semantic coordinates of lexical and grammatical space of words, word pairs and sentences of the natural language are determined. Examples of different types of lexical and grammatical relations between natural language words are offered. The tree of synonymic sentences generation is considered based on the determination of the theme, the rheme, the link, the modality and other levels of natural language meaningful phrases generation.
