We present results of an automatic comparison of valency frames of interlinked adjectival and verbal lexical units based on the valency lexicons NomVallex and VALLEX. We distinguish nine derivational types of deverbal adjectives and examine whether they tend to display systemic valency behavior, or rather the non-systemic one.
The non-systemic valency behavior includes changes in the number of valency complementations and, more dominantly, non-systemic forms of actants, especially a prepositional group.
