7 Concluding Remarks
</SectionTitle>
    <Paragraph position="0"> We have begun with a general constralnt-based perspective about the cognitive mechanism, and shown that a model of sentence processing derived thereof, neutral between comprehension and production, accounts for several linguistic phenomena seemingly unrelated to each other. It has thus been demonstrated that the speculation to derive the model has empirical supports, lending justification for the constraint p~radigm. In particular, our theory has been shown to be more adequate than the determinist approach, which must postulate a procedural design of the human language faculty.</Paragraph>
    <Paragraph position="1"> A computational formalization of our model will be possible in terms of constraint programming, as discussed by Hasida et al. \[8, 9, 17\]. Most of the time, a natural language processing system in terms of procedural programming has been designed to be a series of a syntactic analysis procedure, a semantic analysis procedure, a pragmatic analysis procedure, and so on, in order to reflect the modularity of the underlying constraints. }towever, such a design imposes a strong limitation on information flow, restricting the system's ability to a very narrow range of context. One naturally attempts to remedy this so as to, say, enable the syntactic analysis module to refer to semantic information, but this attempt must destroy the modularity of the entire design, ending up with a program too complicated to extend or even maintain. Constraint paradigm seems to be the only way out of this difficulty. null</Paragraph>
