An Integration of Heterogeneous Resources Based on Semantic Grid

An integration of heterogeneous resources based on semantic grid is presented after thorough studies have been conducted on heterogeneous database integration of digital university libraries. Using OGSA-DAI middleware as the logical intergradation´s layer, it establishes an ontology mapping layer and a semantic grid layer to deal with intermediaries such as grid agents and translation. Being able to describe users´ retrieval needs accurately, this integration framework solves the problem of semantic heterogeneity, making information sharing possible. Experiments show that this integration based on semantic grid could improve search hits efficiently.
