Popis:	The potential for domain models to assist in building medical knowledge bases, particularly to improve their consistency and completeness, has been recognised for some time. As the size of the knowledge base increases, the role of consistency maintaining mechanisms becomes more important, but these may in practice be more difficult to develop. Domain models derived from tightly delimited domains are not likely to be directly applicable to broadly based medical systems such as the Oxford System of Medicine, which is intended to provide wide ranging decision support in general medical practice. A more highly abstracted model, in the form of a deductive database, has been developed in an attempt to overcome some of these difficulties. The model deals primarily with the static part of the knowledge base, defining the types of objects this contains and their interrelations, along with specialist domain theories which help to maintain the integrity of the knowledge. An interactive editing environment, incorporating the domain model and these specialist domain theories has been implemented and is briefly described.
