摘要
情境是知识共享和重用的重要基础，为此提出了基于情境的知识共享与重用方法。讨论了情境的概念与特点，提出了分层的多维情境建模方法。在分层的多维情境模型基础上，提出了基于主情境模型树的情境相似性评估方法。给出了基于情境的知识共享与重用系统的体系框架。通过基于情境的知识共享与重用方法，实现了根据用户情境的自适应知识匹配，提高了知识共享和重用效率。
Context is the important foundation for knowledge share and reuse, consequently a context-based approach is put forward. After the concept and characteristics of context is described, a mulfi-dimension, layered context modeling metthod is proposed. Based on such a model, the context similarity measurement method based on host context model tree is presented. A component-based architecture of context-based knowledge share and reuse system is given. The context-based approach allows to deliver knowledge which is relevant to the current situation of the user, and the efficiency of knowledge share and reuse is improved.
