Polish Sign Language from the perspective of corpus linguistics

Polish Sign Language (polski język migowy, PJM) is a full-fledged visual-spatial language used by the Polish Deaf community. It started to evolve in the second decade of the nineteenth century, with the foundation of the first school for the deaf in Poland. Until recently, PJM attracted very little attention from the linguistic community in Poland. The aim of this talk is to present a large-scale research project aimed at creating an extensive and representative corpus of PJM. The corpus is currently being compiled at the University of Warsaw. It is a collection of video clips showing Deaf people using PJM in a variety of different communication contexts. The videos are richly annotated: they are segmented, lemmatized, translated into Polish, tagged for various grammatical features and transcribed with HamNoSys symbols. The Corpus of PJM is currently one of the two largest sets of annotated sign language data in the world. Special attention will be paid to the issue of lexical frequency in PJM. Studies of this type are available for a handful of sign languages only, including American Sign Language, New Zealand Sign Language, British Sign Language, Australian Sign Language and Slovene Sign Language. Their empirical basis ranged from 100,000 tokens (NZSL) to as little as 4,000 tokens (ASL). The present talk contributes to our understanding of lexical frequency in sign languages by analyzing a much larger set of relevant data from PJM.
