Book Review

In reviewing a book of this kind, it is necessary to answer three questions: (1) how important is the workshop topic, (2) how valuable are the included papers, and (3) how coherent is the volume as a whole? I address each question in turn. In the last decade, knowledgebased systems (KBSs) emerged from being a research subfield within AI to become an application software technology. Although many specific aspects of knowledge acquisition, representation, and reasoning remained active research topics, the methods and tools required to build useful and powerful KBS applications had become sufficiently well understood to facilitate the development and delivery of systems in many diverse domains. However, as organizations began to use the technology, concerns arose about the reliability of KBSs.
