Abstract:
Les systmes d'Extraction de Rponses (ER) rcuprent dans des documents des expressions qui rpondent directement des questions du langage courant. L'ER pour des manuels techniques exige un haut niveau de rappel et de prcision ; pourtant, ce sont de petites units de texte qui doivent tre r- cupres. C'est pourquoi il est important d'effectuer une analyse linguistique dtaille. Nous prsentons ici ExtrAns, un systme d'ER pour des manuels Unix qui utilise une analyse syntaxique complte, une dsambigusation partielle et un module de rsolution d'anaphores pour gnrer les formes logiques minimales correspondant aux documents et la requte. La procdure de recherche se sert d'un algorithme de dmonstration de la requte sur la repr- sentation en clauses de Horn des formes logiques minimales. Les ambiguts non rsolues sont traites l'aide d'une mise en vidence graduelle. Answer Extraction (AE) systems retrieve phrases in textual documents that directly answer natural language questions.
