Ontology Based Automatic Attributes Extracting and Queries Translating for Deep Web

Free registration required

Executive Summary

Search engines and web crawlers can not access the Deep Web directly. The workable way to access the hidden database is through query interfaces. Automatic extracting attributes from query interfaces and translating queries is a solvable way for addressing the current limitations in accessing Deep Web. However, the query interface provides semantic constraints, some attributes are co-occurred and the others are exclusive sometimes. To generate a valid query, the authors have to reconcile the key attributes and semantic relation between them.
