However, most of the web pages were designed for desktop computers equipped with big screens. When browsing on mobile
3、 devices, a user has to scroll up and down to find the information they want because of the limited screen size. Some commercial products reformat web pages. However, the result pages still contain irrelevant information. We propose a system to personalize users mobile web pages. A user can determin
4、e which blocks in a web page should be retained. The sequence of these blocks can also be altered according to individual preferences. 1. Introduction 1.1. Preface Nowadays, we can build a mobile Web application easily. Take the ASP. NET mobile controls 1 (formerly known as MMIT, short for the Micro
5、soft Mobile Internet Toolkit) for example, it reduces the work required for developers to develop applications that target different types of mobile devices, like mobile phones and PDAs. At runtime, MMIT will automatically detect the target device and return the proper presentation format. Thus, the
6、 developers can focus on the application logic without worrying about the presentation issues. Similar academic researches on this topic include 2 and 3. Both of them provide plug-ins for famous IDEs, such as JBuilder and Visual Studio.NET respectively, to assist developers to author a single generi
7、c application. Accompanied with the PUML transformation technology 4, this generic application can be further transformed into specific target formats for different mobile devices. 1.2. Motivation Widespread of mobile devices makes it common to browse Web pages via them. However, most Web pages are
8、mainly designed for desktop computers that are equipped with big screens. When browsing on mobile devices, a user might have to scroll up and down, left and right all the time to find the information they want. Because of the limited screen size, this kind of operation is really not user-friendly at
9、 all. Fortunately, some famous websites have another simplified version of Web content specially provided for mobile devices, such as Google Mobile 5 and Yahoo Mobile 6. On the other hand, it is a heavy burden on Web developers to craft and maintain multiple versions of the same website. Even with t
10、he help of the fascinating toolkits. If we resize the original Web page to fit the width of mobile device, the vertical scroll bar will be too long to view, and the information is crowded. On the other hand, if we provide another version of the original Web page, there may be some important informat
11、ion lost in the mobile version, and the transformation of each page costs a lot for Web page developers. Hence, in this research, we propose a system that is designed to help users to personalize their mobile Web pages for handheld device browsing. 1.3. Research objectives In this sub-section, the f
12、our major research objectives are listed and introduced briefly. 1.3.1. Easy-to-use It does not make sense to launch another program other than the browser to personalize a Web page. When a user surfs on the Internet and finds a Web page that interests him/her, the configuration tool of this system
13、should be able to pop up in the browser window somehow right away. Moreover, all the codes needed to accomplish this job (i.e. personalize Web pages) should be downloaded on the fly when accessed, thus allowing a user to work on different computers at different places. 1.3.2. Personalizing Web pages
14、 visually Web pages are usually composed of header, footer, sidebar, and content areas 7. Parts of them are used to maintain a consistent style for the website, and other parts of them are used for navigation. Some renowned websites may even contain a lot of advertisements on it. In many Web pages,
15、only a few of information is really needed to be shown on the mobile phone screen. This research also aims at allowing a user to determine which parts of a Web page should be retained while browsing this page with their mobile device. A friendly user interface should thus be available for a user to
16、perform this task. For example, with appropriate visual aids (such as highlight), a user can choose blocks in a Web page one by one with different granularity. Through the operation of drag-and-drop, a user can determine the relative position of the chosen blocks according to his/her personal prefer
17、ences. In short, a user can reconstruct a mobile Web page simply with visual manipulations, and does not have to write any line of code. According to the browser market share survey 8, Microsoft Internet Explorer is still by far the most dominant browser on the Web, with 83.88% usage market share, a
18、nd Firefox has increased its share to 10.68%, with the other alternatives, such as Safari, Netscape, Opera, and Mozilla, occupying the remaining share. The downloaded mobile code should work with at least the top two popular browsers, i.e. Microsoft Internet Explorer and Firefox Web browser. 1.3.3.
19、Reducing wireless bandwidth consumption More than screen size constraints, the limited memory and wireless network bandwidth also make it unsuitable for delivering the entire Web page untailored to mobile devices. Before returning a Web page to mobile devices, some adaptation must be taken to pre-pr
20、ocess a Web page according to a users preferences. So that the volume of data transmission to a mobile phone could be reduced, and thus reduce the consumption of wireless bandwidth as well. 1.3.4. Automatic mobile Web page content extraction The content adapting algorithm we proposed can automatically adapt Web pages to mobile devices. Users always only care about a part of the web content.
