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, DARIAH-PL, ELRC, FLaReNet and META-NET.

Current externally funded projects

  • CLARIN-PL (Polish chapter of Common Language Resources and Technology Infrastructure)

  • Chronofleks (A diachronic formal model of Polish inflection and its implementation)

  • CoDeS (Compositional distributional semantic models for identification, discrimination and disambiguation of senses in Polish texts)

  • CORMETAN (Cognitive and sociocultural analysis of metaphoric expressions in Polish texts)

  • HOMADOS (Hampering Misinformation by Assessing Credibility of Online Sources)

  • DARIAH-PL (Digital Research Infrastructure for the Arts and Humanities)

  • ELRC (European Language Resource Coordination)

  • MARCELL (Multilingual Resources for CEF.AT in the legal domain)

  • Kwantyfikatory w języku: użycie i znaczenie (Quantifiers in Language: Use and Meaning)

  • Parthenos (Pooling Activities, Resources and Tools for Heritage, E-research Networking, Optimization and Synergies)

  • Scwad (Compositional distributional modelling of Polish language semantics)

  • SYNAMET (Microcorpus of Synaesthetic Metaphors. Towards a Formal Description and Efficient Methods of Analysis of Metaphors in Discourse)

Some of our past projects

Publicly available tools and resources

Here are some of the tools and resources created within our projects. See CLIP pages for a more exhaustive list of Polish tools and resources, including more tools and resources developed at ZIL IPI PAN.

Some tools (all open source, under GPL; see also CLIP):

  • Świgra – a DCG parser,

  • Spejd – a shallow parsing and disambiguation system,

  • TaKIPI – a morphosyntactic tagger for Polish,

  • PANTERA – a morphosyntactic tagger for Polish,

  • Poliqarp – a corpus indexing and search engine,

  • Poliqarp2 – a new generation corpus indexing and search engine,

  • Dendrarium – a treebank development system (under development),

  • Anotatornia – a system for multi-level manual annotation of corpora (forthcoming),

  • WSDDE – a system for designing and performing Word Sense Disambiguation experiments,

  • Multiservice – web service for various of our tools,

  • TermoPL - multiword terms extraction from text

  • DSmodels - web service for calculating word similarity using Polish word embeddings

  • etc.
