The target of information integration on the Web (IIWeb) is to decrease users’’ loads from repetitive work and let users mash Web data in accordance with their desire. Gadget on Demand (GOD) system, which equipped with automatic Web page fetching and unsupervised Web data extraction function, has been designed for Web information integration from single entry point with multiple runs and present result in various forms including table, list, map and calendar. In this paper we improve GOD system by filling in a new query form with extracted data from other Web sources, thus allowing cross-site information integration with multiple entry points. Furthermore, we add the gadget editing function such that gadget could be modified for different representation method. We also deal with the AJAX problem where Web contents are changed by client-side language like Javascript in a dynamic fashion and solve this problem via external calls to Web browser. We enumerate several real-world applications based on the revised GOD system, including integration of online book store and city library for storage checking and conference CFP calendar from DBWorld. The system demonstrates a potential utilization in Web2.0 generation where users are enabled with tools to create their own gadgets on demand.
