基于分层模型与本体映射的异构电力信息系统集成

Integration of Heterogeneous Electric Power Information System Based on Hierarchy Model and Ontology Mapping

为解决电力信息系统中存在的异构问题,基于信息总线理论,采用层次化结构设计,提出了"企业信息总线"(EI-Bus)的EAI中间件模型,实现了基于规则的柔性机制,并提供可配置的流程定义.针对系统集成中的语义异构,引入电力系统领域本体进行知识表达,提出综合概念相似度和描述相似度的计算方法来实现本体映射,从语义层次上解决多源异构信息的互操作特性.

Existing electric power information systems have various architectures and operation mechanism. Enterprise information bus （EI-Bus） EAI middleware model was proposed to implement integration, which is based on the information bus theory and has a hierarchical architecture. The model is rule-based and its flow definition is configurable. At the same time, electric power ontology was introduced to represent domain knowledge and solve semantic heterogeneity problems. Based on concept and description similarities, an ontology mapping approach was presented which solves the interoperation of multi-source heterogeneous information at the semantic level.
