Parsing mit inkonsistenten Grammatiken

A novel approach to the parsing of natural language based on weighted constraints is presented. Wellformedness conditions are exclusively expressed by means of constraints and no generative rule component is available. In general, constraints can be violated and contradictory requirements of a grammar are tolerated. Additional representational levels allow the integration of different linguistic perspectives into a coherent model, thus contributing jointly to the computation of the most plausible structural interpretation. A number of solution procedures is available for such a parsing problem. Their properties are discussed with respect to possible analogies to human language processing, focussing on robustness against deviating utterances and external temporal pressure.
