FIELD: physics, computer engineering.
SUBSTANCE: invention relates to information technology. The disclosed method includes presenting two texts to be compared in digital form for subsequent processing; indexing the texts to obtain elementary units of first to fifth levels; detecting the frequency of occurrence of elementary units of the fourth level, each being a semantically significant object or attribute, and the frequency of occurrence of semantically significant relationships linking semantically significant objects, as well as the semantically significant objects and attributes; storing the formed elementary units of the second to fifth levels, and the obtained indices together with links to specific sentences of said text; forming from a triad, which are elementary units of the fifth level, a semantic network; ranking the elementary units of the fourth level according to semantic weight by comparing the semantic weight of each of them with a predetermined threshold and removing elementary units of the fourth level having a semantic weight below the threshold; detecting for two compared texts the degree of crossing of their semantic networks.
EFFECT: faster process of comparing texts.
