Abstract: Because of the constantly evolving nature of medical knowledge, updating an expert knowledge base will be a challenge for knowledge-based systems in clinical use. This paper outlines key issues for updating a knowledge-base that is organized around the use fo clinical studies, and provides examples of these issues from the oncology literature. The unique characteristics of a research report often cast previous reports in a new light, altering their interpretation. In addition, expert analysis of a new study may raise novel issues which were not previously considered by the system. This paper provdies a preliminary skeleton upn which future research into updating of expert knowledge-bases can build.
