WDB's Query Interface Extraction Method based on Watir Ruglar Expression

摘要

With the wide application of the Web databases (WDB), it has become a hot topic of the current research to make full use of data. WDB query interface is an important way to get the WDB data, it is a significant prerequisite to obtain the data efficiently that we can realize the full representation and extraction for WDB query interface. This paper presents a new representation based on owl for WDB query interface; at the same time this paper gives the extraction methods based on regular expression and watir for the context of each query interface, form information and the relationship information between the form fields. This work provides an important foundation for the further classification and integration of query interface.
