Project summary
The general aim of the project is to evaluate existing methods and devise new techniques of computational distributional semantics (CDS) in the area of discrimination and disambiguation of senses for Polish. One of the basic problems which has to be solved while analyzing natural language utterances is semantic ambiguity of their elements. Our goal is to elaborate methods determining the meaning of a particular word in the context in which it appears and methods for automatic detection if a word is used in more than one sense in an analyzed text. We want to focus our attention on noun-adjectives constructions and investigate how the meaning of a whole phrase may contribute to creation of sense models for its elements. We also plan to extend these methods to recognize words or phrases which are not used in their literal sense but figuratively. One of the project’s goal is to look for answers for some of general questions, for example, to what degree we will be able to describe sense differences using CDS methods, and which types of models are better suited for such a task and Polish data.
