In this paper we present the results of our work on an implementation of a fast head-driven chart parser for Czech language and constructing the appropriate grammar covering all prevailing grammatical phenomena of Czech. We reassume our previous work on syntactic analysis that was based on the GLR mechanism. We have extended our metagrammar formalism so as to reinforce the declarativeness of the linguistic description. With respect to the massive ambiguity of the grammar we have enriched the head-driven chart parsing mechanism with probabilities obtained from training tree-bank corpus.
