Research on Semantic Integration across Heterogeneous Data Sources in Grid

摘要

Grid technology is a kind of important network information technology grows up in recent years, which can settle the problems of fully sharing and interactive applying among different kinds of resources (such as computing resources, storage resources etc.) distributing in the wide area. This paper focuses on the difficulties of semantic integration across heterogeneous data source in grid. For the existing automatic/semi-automatic schema matching algorithm, it analyzes the advantages and disadvantages and presents a generic schema matching model that full use of the schema and instance information in the schema.
