Application of artificial intelligence to aphasia treatment

Abstract

In this paper we describe SARAH a system devoted to the rehabilitation of aphasic patients. The system has many features of an intelligent tutoring system. Its origininality lies in the patient modelling method used to closely represent the patients' impairments. The patient model provide a means to adapt the rehabilitation sessions to a particular patient. The tests used to diagnose the patient's impairments and then to train him in order to make him avoid his troubles are generated and not retrieved from some knowledge base. This insures the flexibility such a system needs. Finally an expert system is used to schedule the tests during a session.
