基于领域本体的软件资源共享研究

Software resource sharing based on domain ontology

为实现广域分布的、异构软件资源的有效共享和按需服务,提出了一种基于领域本体的软件资源共享框架。该框架按照从具体资源到用户视图自下而上的顺序,划分为资源层、抽象层和呈现层三个层次。在该框架中,利用虚拟化技术封装软件资源,实现软件资源的服务化,屏蔽软件资源的异构性;构建了软件资源本体,将分布的软件资源组成具有语义关系的逻辑上的整体,屏蔽软件资源的分布性;为实现软件资源的动态绑定,建立了匹配和选择机制。根据该框架,实现了一个原型系统,为用户提供更丰富的软件资源和更好的服务质量。

To realize distributed heterogeneous software resource sharing and on-demand service, a software resource sharing framework based on domain ontology was put forward. From the actual resources level to user view level, the framework was partitioned into three layers： resource layer,abstract layer and presentation layer. In this framework, virtualization technology was utilized to encapsulate software resources as services to shield the heterogeneity of software resources. And software resource ontology was constructed to shield the distribution of software resources. To realize dynamic binding of software resources, matching and selection mechanism was established. Based on the proposed framework, a prototype was implemented aiming to provide more rich software resources and better quality of service for users.
