Abstract

The Deep Web is constituted by data that are accessible through Web pages, but not indexable by search engines as they are returned in dynamic pages. In this paper we propose a conceptual framework for answering keyword queries on Deep Web sources represented as relational tables with so-called access limitations. We formalize the notion of optimal answer and characterize queries for which an answer can be found.
