Construction would in principle provide higher descriptive adequacy in computationally based linguistics. After all our heads do not apply programs on stored symbol arrays but are appropriately wired for understanding or producing language. Introductory Remarks 1. For me computational linguistics is not primarily a technical discipline implementing performance processes for independently defined formal structures of linguistic competence. Computational linguistics should be a foundational discipline It should be related to process-oriented linguistics as the theory of logical calculi is to formal linguistics . generative linguistics Montague-grammars etc. . 2. As it stands computational linguistics does not yet meet the requirements for a foundational discipline. Searle s arguments against the claims of artificial intelligence apply fully to computational linguistics Programmed solutions of tasks may execute the task satisfactorily without giving a model of its execution in the organism. Our intentional linguistic acts are caused by and realized in complicated concurrent processes occcurring in networks of neurons and are experienced as spontaneous. This also applies to special cases such as the recognition of syntactic structure parsing . These processes are not controlled and executed by central processor units. 3. Computational linguistics must meet the challenge to satisfy the double criterion of descriptive adequacy Adequacy in the description of what human beings do . parsing and adequacy in the description of how they do it namely by spontaneous concurrent .
