Contribution de la linguistique de corpus à la constitution de langues contrôlées pour la rédaction technique : l'exemple des exigences de projets spatiaux

Abstract : The aim of this work is to improve the clarity and precision of the technical specifications written in French by the engineers at CNES (Centre National d’Études Spatiales / National Centre for Space Studies) prior to the realization of space systems. The importance of specifications (and particularly of the requirements that are part of them) for the success of large-scale projects is indeed widely acknowledged; similarly, the main risks associated with the use of natural language (ambiguity, vagueness, incompleteness) are relatively well identified.In this context, we would like to propose a solution that would be used by the engineers at CNES (who are currently not asked to follow specific writing rules): in that respect, we believe that this solution should be both effective (i.e. it should significantly limit the above-mentioned risks) and not too disruptive (which would make it counterproductive). A Controlled Natural Language (CNL) – i.e. a set of linguistic rules constraining the lexicon, the syntax and the semantics – seems to be an interesting option, provided that it remains close enough to natural language. Unfortunately, the CNLs for technical writing that we have examined are not always relevant from a linguistic point of view.Our methodology for developping a CNL for requirements writing in French at CNES relies on the hypothesis of the existence of a textual genre; besides, we make use of existing Natural Language Processing tools and methods to validate the relevance of the rules on a corpus of genuine requirements written for former projects.
