An approach for knowledge interaction to improve the availability of KBS

In conceptual model of Knowledge-Based System (KBS), there is an antagonistic contradiction of reusability-availability. Researching knowledge interaction in it is a critical method to resolve the contradiction. However, the previous researches have devoted limited endeavor to the problem. This paper starts by reusable UPML architecture, and applies the techniques in distributed software engineering to study the non-manual interactions among reusable knowledge components. The adapter in UPML is first split into two independent parts by operational functions, an architecture for KBS which focuses on the interactions among the components is proposed. Then, Matching Agent Group is taken as the interaction medium between task knowledge and Problem-Solving Method (PSM), and a method to localize the PSM which undertake task is designed. Finally, CORBA bus is regarded as the interaction medium between domain knowledge and PSM, and a means to integrate distributed knowledge source and coordinate PSM is presented. The result of analysis shows that the approach provided in this paper can bridge two abstract levels, namely the reuse of knowledge components and KBS architecture. Thus the availability of KBS will be improved while using this approach.
