Approaches to Context-Based Knowledge Share and Reuse

Context is an important foundation for knowledge share and reuse. In this paper, we first introduce the concept and characteristics of the context, propose a context-based approach to knowledge share and reuse, then construct a multi-dimensional, hierarchical context modeling method. We next present a method for measuring the context similarity based on host context model tree. A component-based architecture of context- based knowledge share and reuse system is also given in the paper. By using this approach, we finally implement an adaptive knowledge delivery and matching system based on user's specific situations, which can greatly improve the efficiency of knowledge share and reuse.
