摘要: 针对现有网格资源管理中间件缺乏对仿真模型资源语义层次的描述和发现匹配这一问题,引入本体概念,定义了仿真模型描述本体,实现了对仿真模型的语义描述;提出了基于本体推理的仿真模型语义匹配算法,将仿真模型语义匹配的量化程度映射到了 上的连续值域,并且支持仿真模型输入/输出的组合匹配;将研究结果应用于仿真网格的仿真模型匹配发现服务的实现中,通过典型的应用实例,有效地验证了提出的仿真模型描述本体和语义匹配算法.

Abstract: To solve the problem about the lack of the semantic description and discovery for the simulation model resources in the grid resource management middleware, the ontology technology was introduced and the description ontology was defined to implement the semantic description for simulation models. The semantic matching algorithm based on the ontology inference was presented. This algorithm maps the semantic matching degree to the continuous value in . Especially, this algorithm supports inputs/outputs composition-based matching of simulation model resources. The research result was applied to the implementation of the simulation model discovery service for simulation grid, and has achieved well validation in the typical application cases.
