MorfFlex CZ

MorfFlex CZ (the latest version is MorfFlex CZ 2.0)  is the Czech morphological dictionary developed originally by Jan Hajič as a spelling checker and lemmatization dictionary. MorfFlex is a flat list of lemma-tag-wordform triples. For each wordform, full inflectional information is coded in a positional tag. Wordforms are organized into entries (paradigm instances or paradigms in short) according to their formal morphological behavior. The paradigm (set of wordforms) is identified by a unique lemma. Apart from traditional morphological categories, the description also contains some semantic, stylistic and derivational information. For more details see a comprehensive specification of the Czech morphological annotation.

The MorfFlex CZ 2.0 dictionary contains 125,348,899 lemma-tag-wordform triples.

MorfFlex CZ 2.0 is an integral part of the PDT-C 1.0 release. There is a full consistency between all the data and the dictionary. 

Authors: Jan Hajič, Jaroslava Hlaváčová, Marie Mikulová, Milan Straka, Barbora Štěpánková.
