Abstract

This paper studies the contribution of semantic and semantic–syntactic analysis to the effectiveness of solving applied text-processing tasks: question answering and extraction of definitions from scientific publications. Methods for solving these problems, which, in addition to morphological and syntactic structures, also use semantic structures of texts, are presented. We carried out the experimental evaluation of these methods and comparison of two approaches to syntactic and semantic analysis: separate and joint semantic–syntactic parsing.
