Satisfaction measure for result in fuzzy reasoning and retrieval - an attempt towards the application of fuzzy logic as the "brainware" of the Internet

Reasoning and retrieval based on uncertain information and imprecise knowledge is often requested in designing and developing intelligent information systems. As a recent trend, the ideas of fuzzy logic have also been widely used in searching the Internet. An important issue for these applications is to equip the reasoning and retrieval with the capability of transmitting the uncertainty from imprecise requirements to a conclusion at a reasonable level of belief and satisfaction. In this paper, we discuss the concept of a satisfaction measure in fuzzy reasoning and retrieval.
