AUTOR: Jakub Waszczuk, Katarzyna Głowińska, Agata Savary, Adam Przepiórkowski AFILIACJA: Narodowy Korpus Języka Polskiego TYTUŁ: Tools and Methodologies for Annotating Syntax and Named Entities in the National Corpus of Polish Referat zostanie wygłoszony w języku angielskim. STRESZCZENIE: The on-going project aiming at the creation of the National Corpus of Polish assumes several levels of linguistic annotation. We present the technical environment and methodological background developed for the two upper annotation levels: the level of syntactic words and groups and the level of named entities. We show how knowledge-based platforms Spejd and Sprout are used for the automatic pre-annotation of the corpus, and we discuss some particular problems faced during the elaboration of the syntactic grammar, which contains over 800 rules and is probably the first chunking grammar for Polish of this scale. We also show how the tree editor TrEd has been customized for manual post-editing of annotations, and for further revision of discrepancies. Our XML format converters and customized archiving repository ensure the automatic data flow and efficient corpus file management. We believe that this environment or substantial parts of it can be reused in or adapted to other corpus annotation tasks.
