| Résumé : | Afin de construire un système de diagnostic médical robuste capable de connaître la bonne maladie entre de nombreuses maladies présentant des symptômes similaires, dans ce travail, nous avons créé une ontologie floue basée sur la logique floue pour traiter les inexactitudes et les incertitudes qui caractérisent certains concepts et relations, où le rôle derrière cela est d'assister notre système. Nous avons créé un programme Java pour gérer cette ontologie en tant que base de connaissances pour ce programme et pour l'utiliser de manière simple également. |
