Abstract

Determining whether a site has a search interface is a crucial priority for further research of deep web databases. This study first reviews the current approaches employed in search interface identification for deep web databases. Then, a novel identification scheme using hybrid features and a feature-weighted instance-based learner is put forward. Experiment results show that the proposed scheme is satisfactory in terms of classification accuracy and our feature-weighted instance-based learner gives better results than classical algorithms such as C4.5, random forest and KNN.
