The paper presents details and comparison of two valuable language resources for Czech, two independent verb valency frames electronic dictionaries. The FIMU verb valency frames dictionary was designed during the EuroWordNet project and contains semantic roles and links to the Czech wordnet semantic network. The VALLEX 1.0 format is based on the formalism of the Functional Generative Description (FGD) and was developed during the Prague Dependency Treebank (PDT) project. We present the tools and approaches that were used within the process of adopting the FIMU Vallex format for the wordnet enriched valency frames. 1.
