Resources and tools for the Polish language

We are trying to make all the constructed resources and tools free of charge for the scientific applications (all interested are kindly ask for a contact).

In the case of commercial application we try to follow the politics of wide availability of our tools, i.e. keeping prices on the minimal level (all interested are kindly ask for a contact).

plWordNet - The Polish Wordnet

SuperMatrix - package for the generation of coincidence matrices (similarity matrices of lexical units) from text corpora.

Among the other applications, SuperMatrix was applied to the construction of semantic similarity function of Polish nouns (results).

TaKIPI 1.5 and Odgadywacz 1.0 - a morpho-syntactic tagger and a morpho-syntactic guesser for Polish

KorMeDIIS - a morpho-syntactically annotated corpus of Polish medical texts

SKIPI - a small corpus of Polish annotated with the shallow syntactic structure

Manufakturzysta - a GUI tool for annotating a corpus

Odgadywacz - morpho-syntactic guesser for Polish

Polish bigram collocations described with the syntactic structure (a tool for their extraction and the results obtained on a very large corpus)

Tools for the construction of stochastic language models for Polish (e.g. for the correction of handwriting OCR)
