Knowledge management for expert systems

As more and more knowledge based applications (such as expert systems) are developed, the problem of duplication of knowledge will become apparent. The solution to this problem lies in the concept of the knowledge base management system (KBMS), which is a repository for knowledge in the same way that a DBMS is a repository for data. Such a system would store the knowledge required by different knowledge based applications in a single base. One important property which is essential for a KBMS is that it should provide knowledge in the form that the knowledge base application requires it. This makes the design of a KBMS considerably complicated. The authors describe a system developed as a first step towards a full KBMS. The system is based on a logic database management system (LDBMS) or deductive database management system (DDBMS) with appropriate extensions
