In this paper* I will argue for a model of grammatical processing that is based on uniform processing and knowledge sources. The main feature of this model is to view parsing and generation as two strongly interleaved tasks performed by a single parametrized deduction process. It will be shown that this view supports flexible and efficient natural language processing. | A BIDIRECTIONAL MODEL FOR NATURAL LANGUAGE PROCESSING Gunter Neumann Lehrstuhl fur Computerlinguistik Universităt des Saarlandes Im Stadtwald 15 Bau 6600 Saarbriicken 11 FRG neumann@ ABSTRACT In this paper I will argue for a model of grammatical processing that is based on uniform processing and knowledge sources.

There are theoretical as well as practical reasons for adopting bidirectionality. Theoretically the assumption of common knowledge sources for both generation and analysis is essential for the view of language as an interpersonal medium and an interface to thought McDonald 1987 . From a psychological point of view there is a certain amount of empirical evidence for shared processors or facilities Jackendoff 1987 . From a system engineering view a bidirectional system produces utterances only from that subset of language that it is capable to understand. Therefore inconsistencies of the language behaviour of the system can be avoided Jacobs 1988 . A fundamental requirement of a bidirectional knowledge base is that it be represented declaratively Appelt 1987 . From this viewpoint one can distinguish two different types of bidirectional natural language systems systems that use uniform knowledge sources but different processes systems that use uniform knowledge sources as well as uniform processes1 Up to now systems that are capable of analysing and producing language fall into the first class . they use different operations for both directions cf. Hoeppner et al. 1983 .
