Abstract
DIAVAL is an expert system for the diagnosis of heart diseases,
based on several kinds of data, mainly from echocardiography. The
first part of this paper is devoted to the causal probabilistic model
which constitutes the knowledge base of the expert system in the form
of a Bayesian network, emphasizing the importance of the OR gate. The
second part deals with the process of diagnosis, which consists of
computing the a posteriori probabilities, selecting the most probable
and most relevant diagnoses, and generating a written report. It also
describes the results of the evaluation of the program.
