# Uncertainty Management in a Distributed Knowledge Based System

Naseem A. Khan, Ramesh C. Jain

*Proceedings of the Ninth International Joint Conference on Artificial Intelligence*, pages 318-319.

## Abstract

In many situations, a knowl e dge source may not give definite hypothesis; it can only express its belief and disbelief in multiple hypotheses . We present a scheme of uncertainty management in such a system . Disbelief is given a con si d era ble importance in our approach. Various experts influence one another and show co-operative behavior by mutually changing their confidence factor values . The final decision about the feasibility of a certain hypothesis is based on the mean value and the consistency of the confidence factor values of the experts.
