Abstract

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
