Abstract
The term valency refers to the number, type and form of arguments that are bound to a word. Valency is specific to any given lexical unit and therefore is covered by lexicons.
This is a preliminary survey conducted with the creation of a valency lexicon of Czech nouns in mind. The authors of such a lexicon have to decide who will be the intended users, how the material will be presented and which aspects of valency behaviour will be covered; we present the choices made by the authors of several Czech, English and German resources that cover the valency of nouns, both machine readable and printed.
