Research Group
Linguistic Engineering Group
The Linguistic Engineering Group (Pol. Zespół Inżynierii Lingwistycznej; ZIL) works on multiple aspects of Natural Language Processing, with a particular focus on information extraction, semantic text processing, and corpus linguistics for Polish and beyond.
The Group develops widely used resources and tools — including the National Corpus of Polish (NKJP), the Polish Dependency Treebank, the Grammatical Dictionary of the Polish Language, terminology extractors TermoPL and TermoUD, and open-source systems such as LAMBO, COMBO, Morfeusz, and Korpusomat — that underpin tagging, parsing, and corpus analysis pipelines for Polish.
ZIL participates in the CLARIN-PL and DARIAH-PL research infrastructures and COST actions (currently as Grant Holder of UniDive), and runs numerous national and international projects funded by sources including NCN, NCBR, FNP, NAWA, NPRH, CEF, Horizon 2020, and DIGITAL.
