Song Juan · Jisuanji gongcheng · 2011
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.
