网格环境下基于本体的知识库模型研究

Ontology-Based Knowledge Repository Model on the Grid

针对知识技术仅用于描述网格服务的可用性以及如何被发现、调度和进化的现状,在开放网格服务体系结构(OGSA)的基础上,给出了知识库本体的形式化定义,分析了构建知识库所需的本体,在此基础上提出了网格环境下知识库通用体系结构及基于语义适配器的存储模型,克服了Sesame存储模型在存储不同格式文件和本体方面所存在的不足,讨论了网格知识库的访问机制.

Knowledge plays a key role in the Grid environment, while no adequate attention has been paid on how to construct knowledge repository on the grid by means of the existing resource. On the basis of OGSA, The paper proposes an ontology-based grid knowledge repository storage model, puts forward the ontologies which are necessary for building KR, studies the general architecture of knowledge repository model as well as the storage model based on the adapter. Finally discusses the access mechanism of grid knowledge repository.
