Аннотация

This paper describes the features that appear in parsing procession of multiword turns (phrasemes) able to act as prepositions. These features are considered in the context of automatic analysis of Russian texts. Such phrases have a fairly high homonymy, which creates some difficulties in analysis and defining semantics and, consequently, reduces the accuracy of parsing. More than 320 phrasemes have been classified on the basis of the assumed homonymy types.
In the course of the study, the phrasemes have been divided into three groups. The first group includes those phrasemes that can definitely be called prepositions, but potentially have some semantic ambiguity. The second group combines phrasemes that are characterized by the part-of-speech homonymy of preposition/adverb. The third group is characterized by phrasemes that determine the construction of two or three parsing options. The occurrence of multivariate parsing is based on the presence of one or two phrases related to different parts of speech, and a simple conjunction of a preposition with a noun.
Within each group, lists of the most common phrasemes have been composed (according to the NCRL), indicating the probability that a certain phraseme may serve as a preposition. The paper also defines the basis on which the compilation of effectively removing homonymy rules for the SemSin parser may rely on. The examples provided in this paper prove that it is necessary to consider not only the direct encirclement of the phraseme, but also its remote context to remove homonymy.
