Description	The paper introduces libkp comparison and evaluation system for the syntactic processing of natural languages. The analysis of sentences is based on context free grammar for given language with contextual extensions (constraints). The tool is language-independent, even though it is optimized for very large and highly ambiguous grammars for Czech (thousands of rules). We discuss the advantages of our modular design as well as efficiency of the processing on the standard evaluation grammars. We also expect this system to be used for comparing and evaluating different CFG-parsing algorithms.
