Abstract:

In this paper, then, we deal not only with belief importance but with wider aspects of consumer modelling. Firstly, for completeness, we briefly outline the major belief models discussed in the literature; secondly, we describe the threshold model in greater detail; thirdly we discuss how threshold and other models may be used by consumers in a combined and sequential manner; finally we outline case histories which shift the emphasis to a more operational and practical level, and which indicate the major role we currently see for threshold.
