Abstract

The current needs of information integration of Deep Web sources, schema matching is one of the most important ways of data integration, E-business, data warehousing, and semantic query processing. However in today systems, schema matching has some significant limitations. There are some problems in schema matching which often have some hidden regularities and semantic conflicts over many sources. These can be essentially leveraged in enabling semantics discover of schema matching. In this paper, we focus on the specific problem of semantic heterogeneity between relational databases schema matching. We propose a clustering algorithm with metadata-labeling from our system's ontology. And also this paper represents a same representation model for all relational schemas with their own ontologies to map the best results of semantic mapping. In this paper, we compare the experimental results of schema matching for relational databases.
