| 摘 要： | 针对电力系统数据集成中存在的语义异构问题，提出一种基于本体的数据集成框架。依据电力参数估计系统的数据需求模型，分析数据集成存在的语义冲突类型，在传统数据集成框架的数据集成中间件模块中加入本体语义描述模块。采用本体描述信息资源域中的概念，通过实现语义冲突主动发现并构建语义映射关系。实验结果表明，该框架能有效解决数据集成过程中的语义异构问题。

| Abstract: | According to the data request model of power parameter estimate system,and semantic conflict type existing in the process of data integration,a heterogeneous data integration frame based on ontology is proposed to solve semantic heterogeneity problem.It improves traditional data integration structure by adding ontology semantic describing structure into data integration mediator.Based on describing the concept of domain by ontology,this structure solves the semantic heterogeneity problem existing in heterogeneous data integration,by finding semantic conflict initiative and constructing semantic mapping relations.Experimental result shows the feasibility and effectively of integration framework based on ontology proposed in this paper. |
