| 摘要: |
| NKI(国家知识基础设施)是一个大规模知识库,它用框架来表示本体中的概念,用Hom逻辑程序作为自动推理.给出NKI中的本体、框架和逻辑理论的形式表示以及形式表示之间的转换,并证明如果将本体、框架和逻辑理论看作是3个范畴,则这些转换是这3个范畴之间的函子.这个结果保证了在NKI中,基于Horn逻辑程序的推理关于用本体和框架表示的知识库是正确的. |

| Abstract: |
| NKI (The National Knowledge Infrastructure) is a large-scale knowledge base, which uses frames to represent concepts in ontologies, and uses Horn logic programs as the automated reasoning. The formalizations of ontologies, frames and logical theories in NKI, and the transformations between the formalizations are given, and proved to be functors between ontologies, frames and logical theories if they are taken as categories in the theory of category. The result proved in this paper guarantees that in NKI, the inference based on the Horn logic programs is correct with respect to the knowledge base represented by ontologies and frames. |
