8. A computer-implemented method of aligning fragments of a first text in a first language with corresponding fragments of a second text, which is a translation of the first text into a second language, comprising: preliminarily dividing the first and second texts into fragments; generating a hypothesis about correspondence between at least first fragment in the first text and at least second fragment in the second text; performing a lexico-morphological analysis of the first and the second fragments using linguistic descriptions; performing a syntactic analysis of the first and the second fragments using linguistic descriptions and generating a syntactic structure for the first fragment and a syntactic structure for the second fragment; generating a semantic structure for the first fragment and a semantic structure for the second fragment, wherein the semantic structures are directional acyclic graphs with nodes that are assigned elements of semantic hierarchy; estimating the degree of correspondence between the semantic structure for the first fragment and the semantic structure for the second fragment, wherein estimating the degree of correspondence between the semantic structures includes identifying correspondence of tree structure, deep slots, non-tree links, and semantic classes; and if the degree of correspondence between the semantic structure for the first fragment and the semantic structure for the second fragment satisfies a predetermined threshold, saving the generated syntactic and semantic structures for the first fragment in connection with the first fragment; and saving the generated syntactic and semantic structures for the second fragment in connection with the second fragment.
