Sentence Context and Resolving Lexical Ambiguity for Special Groups of Words on the Base of Corpus Data

This article presents the results of resolving lexical ambiguity for special groups of words that are used to denote natural phenomena. We applied the corpus data from the National Corpus of the Russian Language and the National Corpus of the Tatar Language. Also, we developed the structures of sentence context and defined important features of the method of resolving lexical ambiguity. Certain typical elements (lexical, syntactic ones) associated with the meaning, were identified in the structure of sentence contexts. For contextual analysis, we developed program tools for extracting context constituents (noun phrases and verb phrases). Finally, we described the results of our first experiments on establishing the meaning of ambiguous words (natural phenomena).
