Research on Automate Discovery of Deep Web Interfaces

摘要: The main means to obtain information from Deep Web is submitting query condition through the provided interfaces, so it first problem that needs be solved for data integration system. At present, most researchers think of interface merely defined within form html tag. This paper firstly proposes concept block, then designs block location method based on page and vision information, finally takes judgment whether a or not as special multi-class classification problems by applying algorithm combining C4.5 decision tree SVM. experiment adopts TEL-8 sets UIUC, findings indicate in this get an accuracy 97.30%, has good feasibility practicability.
