A Real-Time Web Contents Adaptation for Mobile User

We present a system that transforms web content in the internet effectively to the corresponding mobile content adapted to a mobile terminal such as a PDA or a mobile phone. The primary goal of this research is to reuse web contents in a wireless internet environment without any additional effort of rebuilding them at scratch for contents adaptation to reduce costs and efforts needed to develop wireless contents for mobile user. Our current target is news contents, whose content is frequently added and updated. To process them in real-time, all of the hyperlinked pages to the index page of a target web site are extracted and then stored into a web cache. The secondary goal is to develop more convenient user interfaces to read mobile contents easily with a mobile terminal. To do this, non-textual information of a web page is treated independently. It consists of a distinct mobile page hyperlinked to the page which has textual information only. Besides, we propose a technique, called page splitting, to navigate pages with button controls instead of conventional scroll up/down controls. Our experimental results say that by manipulation of navigation buttons with the aid of the page splitting becomes more efficient to read mobile content as its size is larger. The proposed system has been well operated for both well-known domestic and international news portal sites, including the New York Times.
