Organizing Structured Deep Web Sources by Query Schemas
Chen Juan · Modern Computer · 2006
In the recent years, the Web has been rapidly deepened with the databases online. On this deep Web, numerous sources are structured, providing schema-rich data-Their schemas define the object domain and its query capabilities. The structured deep Web thus presents challenges for large-scale information integration. Clustering is one of the important approaches in data mining, this paper studies organizing structured Web sources by query schemas with the hierarchical agglomerative clustering algorithm. And we use pre-clustering and post-classification techniques to improve it. Our experiments show the effectiveness- By clustering the query schemas, the hierarchical agglomerative clustering algorithm can accurately organize sources into object domains.
