Case-based reasoning (CBR) has been widely used in many real-world applicat
ions. In general, CBR systems propose their answers based on solutions atta
ched with the most similar cases retrieved from their case bases. However,
in our vehicle insurance domain where the dataset contains a large amount o
f inconsistencies, proposing solutions based only on the most similar cases
results in unacceptable answers. In this article, we propose a hybrid-reas
oning algorithm which employs a number of statistical models derived from a
nalysis of the entire dataset as an alternative reasoning method. Results o
f our experiments have shown that the use of these models enable our experi
mental system to propose better solutions than answers proposed based only
on the closest matched cases. (C) 1999 Elsevier Science B.V. All rights res
