知识表示及其推理是研究知识集成服务的关键技术。本文研究了3个核心问题:一是模糊逻辑知识表示方法;二是将因素空间理论应用于与具体资源相关领域中的知识表示,实现统一的知识表示方法;三是对基于因素空间理论的知识表示方法进行运用,基于这种表示方法实现真值流知识推理机制,为实现语法层面的知识集成提供理论基础。 Knowledge representation and reasoning are the key technologies to research knowledge integration services. This paper studies three core issues: one is the fuzzy logic knowledge representation; the other is the application of the theory of factor space to the knowledge representation in specific resource-related fields to achieve a unified method of knowledge representation; the third is the knowledge based on factor space theory Representation method based on this representation method to achieve truth-value flow of knowledge reasoning mechanism for the realization of knowledge-based grammar level to provide a theoretical basis.
