A Morphosyntactic Brill Tagger for Inflectional Languages

  • Szymon Acedański
Part of the Lecture Notes in Computer Science book series (LNCS, volume 6233)


In this paper we present and evaluate a Brill morphosyntactic transformation-based tagger adapted for specifics of highly inflectional languages. Multi-phase tagging with grammatical category matching transformations and lexical transformations brings significant accuracy improvements comparing to previous work. Evaluation shows the accuracy of 92.44% for the Polish language which is higher than the same metric for the other known taggers of Polish: stochastic trigram tagger (90.59%) and hybrid tagger TaKIPI employing decision tree classifier and automatically extracted rule-based tagger used for tagging the IPI PAN Corpus of Polish (91.06%).
