PlWordNet

plWordNet serves as a thesaurus-dictionary where concepts (synsets) and individual word meanings (lexical units) are defined by their location in the network of mutual relations, reflecting the lexico-semantic system of the Polish language.

The works have been carried out by The WrocUT Language Technology Group G4.19 since 2005,[2] funded by the Ministry of Science and Higher Education and by the EU.

Some lexical units are provided with the information about stylistic register, short definition, usage examples and link to the relevant Wikipedia article.

The most important element defining words meanings are lexico-semantic and derivational relations, which hold between synsets and between lexical units.

[9] Based on the relations assigned to the synsets and units, tools for natural language processing can conclude about meaning of the lemma, which is important for example in word-sense disambiguation.
