Grammars which can be re-used to automatically analyse languages (phase ii)

Development of a set of grammars which can be re-used in
many different application areas together with the tools
which will support the customization of the grammars and
their integration into a special application environment

The GRAAL project will develop new intelligent systems for textual information processing allowing, in particular, the development of high quality and cost effective natural language interfaces to databases, automatic text indexing and computer-aided translation systems. The project is based on real applications, aims at developing short term results and wishes to demonstrate the economic as well as the theoretical interest of a modular and generic approach to building linguistic tools. The GRAAL project will develop a set of grammars which can be re-used in many different application areas together with the tools which will support the customization of the grammars and their integration into a specific application environment. Particular emphasis will be laid on the following aspects: - definition of a standard representation of grammars - definition and development of associated parsers - high re-useability of the grammars - ease of evolution and maintenance - test and validation on a wide set of real industrial applications in the field of automatic translation and text monitoring. The GRAAL project will use the extensive experience of the participants in the field of textual information processing. All participants have already developed and exploited a significant number of operational natural language processing systems, and are now convinced that the technology can go one step further to help them solve other problems. The product which they intend to develop by the end of the project is a toolbox comprising: - a library of modular grammars and their associated parsers - associated tools to build a specific grammar for a particular application: selection of modules, integration of area-specific components, etc. - associated tools to maintain the library and to incorporate new modules. Other kinds of projects delivered by the project will be those among the applications that will arrive at an industrial level. These products differ from the toolbox in the sense that they should always be used in the same context (e.g. technical text indexing, yellow pages interrogation, etc.). The GRAAL toolbox will be available on standard Unix work stations and will be operational in a network environment.
