The Linguistic Engineering Group

The Linguistic Engineering (LE) Group is part of the Department of Artificial Intelligence at the Institute of Computer Science, Polish Academy of Sciences (ICS PAS).

People

Research

The main research areas of the Group are:

• (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 and FLaReNet.
