Knowledge integration in a robust and efficient morpho-syntactic analyzer for French

We present a morpho-syntactic analyzer for French which is capable of automatically detecting and of correcting (automatically or with user help) spelling mistakes, agreement errors and certain frequently encountered syntactic errors. Emphasizing the specific language knowledge that is used, we describe the major subtasks of this analyzer: word categorization by dictionary look-up and spelling correction, construction of a parse tree or of a forest of parse trees, correction of syntactic and morphological errors by processing the parse tree. The spelling corrector module is designed to help correct the spelling mistakes of a French novice, as opposed to those of an experienced typist. The syntax analysis module is driven by an empirical grammar for French and is based on the work of Tomita. The presentation is based on the design and implementation of a prototype of the system which is written in Lisp for the Macintosh computer.

The implementation of a computational grammar of French using the grammar development environment

The design and implementation of a large-coverage computational grammar of French is described. This grammar is compared to a comprehensive computational grammar of English which was implemented using the same computer workbench. Although many similarities may be observed in the two grammars, there are important structural differences which can be traced back to features specific to the French language, notably agreement and eliticization.

Coordination of subject markers in arabic and typed categorial logic

In Standard Arabic, object markers and subject markers behave differently, although they share some properties We are concerned here by their morphosyntactic status; whether they are arguments or agreement markers The status of object markers is not an issue in itself, but the status of subject markers is one The agreement asymmetries lead us to stipulate that, when subject markers are doubled by NPs whether these NPs are coordinated or not, they are agreement markers and not arguments This analysis is implemented by means of an applicative combinatory categorical grammar (ACCG).
