The main goal of the project is to create consistent electronic dictionary rendering underlying structure of Czech verbs and additional syntactico-semantic information useful for the analysis and synthesis of Czech texts as well as other applied tasks in NLP.
The Valency Lexicon of Czech Verbs is a collection of linguistically annotated data and documentation, resulting from an attempt at formal description of valency frames of Czech verbs.
The lexicon provides:
The lexicon is available in three formats:
VALLEX 3.0 is an enhanced, cleaned and corrected successor of VALLEX 2.5. It contains - in addition to the information stored in VALLEX 2.5 - also
VALLEX 3.0 has been developed within the project Delving Deeper: Lexicographic Description of Syntactic and Semantic Properties of Czech Verbs supported by the Grant Agency of the Czech Republic, grant No. GA P406/12/0557.

VALLEX 2.5VALLEX 2.5 is a cleaned and corrected successor of VALLEX 2.0. It was released electronically at the end of 2007 and since spring 2008 it is available also as a book issued by Karolinum Press, the publishing house of Charles University in Prague. |
VALLEX 2.0In VALLEX 2.0, there are roughly 2,730 lexeme entries containing together around 6,460 lexical units ("senses"). VALLEX 2.0—unlike traditional dictionaries and also unlike VALLEX 1.0—treats a pair of perfective and imperfective aspectual counterparts as a single lexeme (if perfective and imperfective verbs would be counted separately, the size of VALLEX 2.0 would virtually grow to 4,250 verb entries). |
VALLEX 1.0VALLEX 1.0 contains roughly 1400 verbs (counting only perfective and imperfective verbs, but not their iterative counterparts) – 1000 most frequent Czech verbs were selected according to their number of occurrences in a part of the Czech National Corpus (only 'být' (to be) was excluded); then their perfective or imperfective aspectual counterparts were added, if they were missing. |
VALLEX can be used free of charge by any academic, educational or research institution, or other organization or individual making use of VALLEX for non-commercial research and/or education purposes. Legal usage of VALLEX is conditioned by filling the registration form.
