In this paper we present an analysis of the structure of medical knowledge for the purpose of the construction of knowledge based systems. We discern three different views on knowledge that each have a different but complementary function with regard to reusability. We show that each of these views suggests distinct activities in the knowledge engineering process. The reported knowledge organisation is a key element of the the games methodology for the construction of medical knowledge based systems.
In this paper, we discuss structuring principles of medical domain knowledge in knowledgebased applications. We take a knowledge-level [Newell, 1982] viewpoint, abstracting from potential symbolic representations of the knowledge. We distinguish three views on medical knowledge, namely (i) the vocabulary of basic medical terms, (ii) the knowledge types distinguished in an application, comprising the ontology of the application, and (iii) the knowledge roles, pointing to the way in which knowledge is used during problem solving. Multiple views on medical knowledge are useful for a number of purposes. In this paper we focus on two aspects:
ffl The identification of generic, reusable knowledge elements.
