An Integrated Competence-Performance Model, A Prototype for Morpho-Conceptual Parsing and Consequences for Information Processing

We present the basis of an integrated model of language knowledge and language use relying on asymmetry. We consider the properties of morphological structures and argue that asymmetry contributes to the analysis of their form and interpretation. We implement our model in a morphological parser and compare the properties of this parser with another morphological analyzer. As existing information processing systems are beginning to integrate articulated lexical knowledge (Copestake & Briscoe, 1996; Paziena 1997; Boguraev & Pustejovsky, 1996, and related works) we expect that a refinement of their architecture with asymmetry-based parsing will increase their performance. The organization of this paper is the following. The first part presents our integrated model. The second part identifies the main features of a prototype for morphological analysis incorporating the asymmetry-based grammar. The last section considers the consequences of the inclusion of the parser in information processing systems.
