| 摘 要： | 专家系统中的知识的不确定性推动了近似推理的研究。而实施近似推理的前提是完成近似匹配。由此,本文首先讨论专家系统中有关不确定性的问题,继而通过引入λ—匹配和ε—匹配的概念探完了专家系统中的近似匹配及基于近似匹配的近似推理的策略和方法。从而修改和完善了文献1,3,4]的部分结果。

| Abstract: | Knowledge uncertainty in expert systems has advanced the research on approximate reasoning . But the premise of processing approximate reasoning is to complete approximate matching, in this paper we first discuss uncertainty-related problems in expert systems, then , we explore the strategies of approximate matching and approximate reasoning based on approximate matching by introducing λ-matching and e-matching . Therefore, a few of results in reference 1,3,4] are improved. |
