The Valency Lexicon of Czech Verbs, Version 2.5 (VALLEX 2.5), is a collection of linguistically annotated data and documentation, resulting from an attempt at formal description of valency frames of Czech verbs. VALLEX 2.5 has been developed at the Institute of Formal and Applied Linguistics, Faculty of Mathematics and Physics, Charles University, Prague. VALLEX 2.5 is a successor of VALLEX 1.0, extended in both theoretical and quantitative aspects.
VALLEX 2.5 provides information on the valency structure (combinatorial potential) of verbs in their particular senses. VALLEX is closely related to the Prague Dependency Treebank project: both of them use Functional Generative Description (FGD), being developed by Petr Sgall and his collaborators since the 1960s, as the background theory.
In VALLEX 2.5, there are roughly 2,730 lexeme entries containing together around 6,460 lexical units ("senses"). Note that VALLEX 2.5 - according to FGD, but 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 2.5 would virtually grow to 4,250 verb entries). To ensure high quality of the data, all VALLEX entries have been created manually, using several previously existing lexicons as well as corpus evidence from the Czech National Corpus.
