This book presents a method for database schema§matching, the problem of identifying elements of two§given schemas that correspond to each other. Schema§matching is useful in e-commerce exchanges, in data§integration/warehousing, and in Semantic Web§applications. It first presents two corpus-based§methods: one method is for determining the semantic§similarity of two target words and the other is for§automatic word segmentation. Then it presents a§name-based element-level database schema matching§method that exploits both the semantic similarity and§the word segmentation methods.
