【摘要】 为了解决如何消除知识工程中知识的冗余性和矛盾性,本文以超图及其函数依赖图(FD-图)为基础,引入了扩展超图及其扩展函数依赖图(AFD-图).为了将扩展超图及其AFD-图进一步应用于大型知识库和分布式知识库中,又引入了跨度的概念,并且详细阐述了解决将扩展超图及其AFD-图应用于大型知识库和分布式知识库中有关问题的基本原则.更多还原

【Abstract】 In order to solve the knowledge redundancy and non-consistency problems in the production rules which are important in the knowledge representation and knowledge acquisition, this paper introduces the augment hypergraph and its augment functional dependency graph (AFD-graph), based on the hy-pergraph and its functional dependency graph. It also introduces the concept of span so that the augment hypergraph and its AFD-graph can be used in large and distributive knowledge engineering.更多还原
