Description This paper presents an exploitation of the lexicon of verb valencies for the Czech language named VerbaLex. The VerbaLex lexicon format, called \emph{complex valency frames}, comprehends all the information found in three independent electronic dictionaries of verb valency frames and it is intensively linked to the Czech WordNet semantic network. The NLP laboratory at FI MU Brno develops a deep syntactic analyzer of Czech sentences, the parsing system \texttt{synt}. The system is based on an efficient and fast head-driven chart parsing algorithm. We present the latest results of using the information contained in the VerbaLex lexicon as one of the language specific features used in the tree ranking algorithm for the Best Analysis Selection algorithm, which is a crucial part of the syntactic analyser of free word order languages.
