Task models for knowledge elicitation
Michael Wilson · 1989
Knowledge elicitation cannot be lead solely by the expert. Elicited knowledge must be analysed and represented by the knowledge engineer. When a knowledge engineering project is started some framework must exist of what is likely to be encountered and the representation to be used for it. Given our present knowledge of the psychology of expertise the top-down influence on knowledge elicitation must be derived from previous analyses of the tasks likely to be performed by the expert. As knowledge engineers become more experienced they will build up there own library of previously analysed tasks. Before then, they must rely on general task analyses and their model libraries. This chapter reviews developments in task models which can be used to guide decisions during knowledge acquisition. - 2 - Introduction When we start knowledge acquisition we have a series of techniques at our disposal. We are aware that we should not alienate the expert, or appear as though we are going to replace ...
