STABLE PHRASES WITH TWO SEMANTIC MEANINGS
The features of processing ambiguous phrases (phrasemes) capable of performing the function of prepositions in the automatic analysis of Russian-language texts are considered. The complexity of the analysis of such phrasemes lies in a sufficiently high homonymy, which reduces the accuracy of automatic parsing of sentences and, moreover, the definition of semantics. The results of homonymy studies of 20 phrasemes that can play the role of prepositions or be simple combinations of words are presented. Rules have been developed to remove part-of-speech and syntactic homonymy in automatic text analysis.First, control words are found in the right and left contexts, then a semantic-syntactic (using a semantic classifier) analysis of these control words is carried out.Based onthis, a decision is made whether the phrase is a compound preposition. It is noted that the phrasemes under consideration, in addition to the direct lexical meaning, also have a figurative meaning, which corresponds to the prepositional phrase.
