Objective
Many of the problems currently confronting sentence-based NLP systems are due to the lack of an adequate theory of discourse. The interpretation of linguistic expressions is often determined by extrasentential information, and systems that do not take such information into account almost inevitably perform inadequately. Most treatments of discourse phenomena (eg pronoun resolvers) follow a procedural methodology which makes them univertible and hence unsuitable for integration into an NLP system. This project aims at a declarative theory of discourse, a grammatical approach to pronouns, temporal anaphora and discourse relations.
The project will be based on selected existing theories of discourse, and will build on these to arrive at a declarative theory of discourse for NLP, to be implemented in the ALEP environment. The ALEP platform is an environment for lingware development and testing being developed by BIM with Community funding. Another EC-funded project whose results will greatly benefit the present project is ET10/61 'Formal Semantics for Discourse'. This is a research project divided into five clusters of work packages, each with its own objective.
A discourse analysis package will produce linguistic specifications of discourse relations concentrating on nominal anaphora, temporal anophora and sentence relations. A work cluster on representation will specify the representation of discourse information is a sign-based grammar. A computation package will investigate the ways in which discourse information can be computed using principles such as declarativity, reversibility and compositionality, and how these can be reconciled with the theory developed in previous work packages. The implementation work package will result in a partial implementation of the discourse model in the ALEP system developed in an ongoing EC-funded project. Evaluation, reusability, comparisons with other work and the relevance of the project to the NLP community will all receive careful attention.
The project investigates the feasibility of NLP systems which combine a number of desirable characteristics (such as being declarative and discourse-based) and will make significant contributions to the following state-of-the-art interfaces:
anaphora resolution and declarativity
discourse and sign-based representation
sign-based representation and generation.
It is expected to yield important in terms of setting standards in the NLP community. Results will be presented at conferences and workshops and be made accessible to a wide range of grammar writers and computational and theoretical linguists.
