Diagnostic d'erreurs dans le projet FreeText

Abstract : This paper presents an overview of research conducted within the FreeText project in order to build an automatic error diagnosis system for learners of French as a foreign language. After a brief review of the main features of the project and of the learner corpus collected and exploited within the project, the paper focuses on the error diagnosis system itself, and more specifically on two of its components: a syntactic checker making use of two different diagnosis techniques to detect errors of purely grammatical nature; and a sentence comparison tool which compares a learner's answer with a correct one stored in the system to detect possible semantic discrepancies, such as referents or word usage. We then compare the results of our system to the performances of a commercial tool. Advantages of such an automatic system and leads for further research are finally discussed.
