In our paper we discuss an approach to semiautomatic corpus processing aimed at analysing verb valencies in Czech and consecutive determining the type of TIL (Transparent Intensional Logic) construction that belongs to the verb. Obtaining the type of the construction is a corner-stone of the logical semantic analysis of sentences. TIL is a highly suitable tool for representing the semantic structure of utterance as it is presented later in the paper. Our approach is based on the technique of partial syntactic analysis using a special kind of LALR grammar processing tool.
