Automatic classification of deep web databases with simple query interface

Deep Web database classify is a key operation in organizing Deep Web resources. We address the problem of identifying the domain of Web databases with simple query interface. The existing methods can not effectively classify this type of Web databases, to solve this problem, we propose an new framework that can automatically and accurately classify Web databases with simple query interface based on probing query. The core of this framework is a domain specific classifier(DSC). DSC is constructed by using the features that can be easily extracted from advanced query interfaces(forms) in domain. According to the similar relation among result schemas, interface schemas and global schemas of Web database, Based on its result schemas, a new Web database with simple query interface can be classified by DSC. Experiments running on real structured Web databases collected from the Internet show that our provides an effective and scalable solution for classifying Web databases with simple query interface.
