A knowledge base repository model for multiple domain problems of distributed expert system

An expert system that accommodates multiple domain problems is potentially accessed by a large number of users. This can degrade service performance if it is applied only at a single service center. The distributed service centers are an alternative to solve the problem, but the knowledge base between dispersed servers needs synchronization mechanism. This study proposes a knowledge base repository model in the form of a database for multiple domain problems and scattered expert systems. The repository model was developed to mark the knowledge base elements to be exchanged between servers. A data exchange mechanism is illustrated to accommodate the data exchange between expert system servers.
