<p>A description is given of a multiuser knowledge-based system (MKBS) model. In this system, knowledge is represented in a collection of interlinked, largely autonomous user knowledge bases (UKBs) and supports use of the system by multipole heterogeneous users. The UKBs are defined so that while each user's view of the knowledge base is limited to the local UKB, problem solving can be achieved using knowledge from multiple UKBs. Different ways of sharing knowledge, including rules, are discussed. A method for rule translation that enables a rule to be used in multiple UKBs is presented. Issues relating to consistency maintenance and explanation in MKBS are addressed.</p>
