Abstract :
In our previous work (Proc. 6th Int. Conf. on Software Eng. and Knowledge Eng., pp. 344-351, 1994), we have observed that the insufficient reasoning principle in probability theory is a key role in distinguishing updating beliefs and combining evidence and we suggested a new rule-the proportional sum for updating evidence within the framework of the Dempster-Shafer theory of evidence. In this paper, we discuss the calculation of updating belief in Gordon-Shortliffe´s (1985) hierarchical structure
