ABSTRACT
Because knowledge systems rely on problem solving knowledge, knowledge acquisition is an important activity in the knowledge engineering life-cycle. In the early days of expert systems (Hayes-Roth et al., 1983) this expert knowledge was acquired and directly encoded into a rule-based formalism (Davis, 1979). This approach is often called 'knowledge acquisition as mining'. The assumption here was that knowledge could be directly transferred from an expert to a computer in a form suitable for problem solving.
