面向GMA目录服务的领域本体建模研究

Research on domain ontology modeling for directory service of GMA

提出构建目录服务本体对GMA目录服务组件维护的网格资源信息提供语义一致的描述,从而弥补使用关系数据库或XML组织信息时产生的语义缺陷。结合国家网格甘肃计算节点的实际情况基于描述逻辑进行本体建模,对支持任意实际运行的网格的目录服务本体及其语义进行形式化分析,提出了可以满足这类本体的模型。基于OWL-dl构建了一个目录服务本体的实例,使用sparql语言进行查询,验证了目录服务本体的正确性及可行性。

Constructing directory service ontology （DSO） is proposed to provide a semantically coherent representation for the grid resource information maintained by directory service component of GMA, thereby making up the lack of semantic support generated in using a relational database or XML for information organization. A DSO model is constructed based on Description logic according to the practical situation of the node of GSPCC in China National Grid. A formal analysis for DSO and its semantics is given to support an arbitrary actual running grid and the model satisfying this kind of ontologies is proposed. An instance of DSO is constructed based on OWL- dl and then queried using sparql language. The results validate feasibility and correctness of directory service ontology.
