AUTOR: Marcin Woliński AFILIACJA: IPI PAN TYTUŁ: The tools for morphological description of Polish developed and used at IPI PAN STRESZCZENIE: I will start with a presentation of Morfeusz, a morphological analyser (an inflectional dictionary) of Polish. The presentation will cover linguistic data used and its representation in the program. The next resource mentioned will be a dictionary of Polish proper names developed at IPI PAN. I will show the tool used to build this dictionary and describe the format of the data. I would also like to discuss some extensions to the current version of Morfeusz needed/useful for processing of multi-word proper names.
