Issues in Knowledge Level Modelling

Walter Van de Velde

Abstract:

Since its introduction in the early 80s the notion of knowledge level has been an important catalizer of research in knowledge systems. This chapter discusses how it is being turned into a useful tool for the development of knowledge systems and how the original and present interpretations can be tied together again. It shows how the knowledge level changed our views on what knowledge systems are and how the problems with first generation expert systems might be overcome. Two other issues are discussed in some more detail. The first one is the precise methodological role of the knowledge level. The second issue concerns the nature of knowledge level theories of problem solving and its implications for next generation architectures. 0footnote
