Lightweight data integration method based on semantics
Wang Ming-yu · Jisuanji gongcheng yu sheji · 2012
To solve the problems of high costs and lacking of semantics in the existed data integration approaches,the lightweight data integration method with semantics is studied.Firstly,the ontology and metadata is summarized.Then,a lightweight data integration method based on semantics is presented and its two main processes,namely ontology identification and metadata extraction,ontology mapping and metadata integration based ontology mapping,are analyzed.Finally,instance analysis is achieved.The analysis results show that the presented method is feasible.Using metadata integration instead of data integration can avoid the moving and storage of huge amounts of data and reduce the cost of integration and make the process of data integration lightweight.At the same time,the introduction of semantic information can make the presented method provide better support for the upper application.
