New Inflectional Lexicons and Training Corpora for Improved Morphosyntactic Annotation of Croatian and Serbian

In this paper we present newly developed inflectional lexcions and manually annotated corpora of Croatian and Serbian.We introduce hrLex and srLex-two freely available inflectional lexicons of Croatian and Serbian-and describe the process of building these lexicons, supported by supervised machine learning techniques for lemma and paradigm prediction.Furthermore, we introduce hr500k, a manually annotated corpus of Croatian, 500 thousand tokens in size.We showcase the three newly developed resources on the task of morphosyntactic annotation of both languages by using a recently developed CRF tagger.We achieve best results yet reported on the task for both languages, beating the HunPos baseline trained on the same datasets by a wide margin.
