Extraction of Form Attribute and Query Interface Integrating from Deep Web

Abstract

In this paper we describe a new strategy based on internal code and visual unit to extract query interface schema. In the process of extraction, there are still some aspects that should be improved. In order to access multiple network databases in deep Web, which is a time-consuming work, how to integrate a unified query interface is one potential problem. Integration is a process of matching attributes that are in the query forms based on domain ontology. It can save a lot of time and energy to visit abundant network databases. Experimental results also show that our method outperforms the state-of-art integrator from the perspective of traditional performance metrics.
