Abstrakt
NomVallex is a manually annotated valency lexicon of Czech nouns and adjectives that enables a comparison of valency properties of derivationally related lexical units. We present new developments in how the lexicon facilitates research into changes in valency across part-of-speech categories and derivational types.
In particular, it provides links from derived lexical units to their base lexical units and also allows to search and display a base lexical unit together with all lexical units directly derived from it. Using an automatic procedure, any difference in valency between two derivationally related lexical units is specified.
As a case study, focusing on nouns and adjectives directly or indirectly motivated by verbs, the facilities provided by the lexicon are used to show differences in what ways the particular deverbal derivatives representing various derivational types express the valency complementation standing in the base verbal construction in the subject position.
