Extraction and Recognition of Polish Multiword Expressions using Wikipedia and Finite-State Automata
Paweł Chrząszcz · 2016
Linguistic resources for Polish are often missing multiword expressions (MWEs) -idioms, compound nouns and other expressions which have their own distinct meaning as a whole.This paper describes an effort to extract and recognize nominal MWEs in Polish text using Wikipedia, inflection dictionaries and finite-state automata.Wikipedia is used as a lexicon of MWEs and as a corpus annotated with links to articles.Incoming links for each article are used to determine the inflection pattern of the headword -this approach helps eliminate invalid inflected forms.The goal is to recognize known MWEs as well as to find more expressions sharing similar grammatical structure and occurring in similar context.
