Research

The main research areas of the Group

• (Polish) corpus linguistics; cf. the IPI PAN Corpus of Polish and the National Corpus of Polish,

• syntactic and semantic parsing of Polish; cf. Spejd and Świgra,

• extraction of linguistic knowledge from corpora,
• information extraction,
• sentiment analysis,
• morphosyntactic system of Polish,
• generative linguistic formalisms, esp., HPSG and LFG.

The Group is a member of CLARIN, FLaReNet and META-NET.
