Before returning a Web page to mobile devices, some adaptation must be taken to preprocess a Web page according to a user39。畢業(yè)設(shè)計(論文)外文資料翻譯學(xué) 院： 計算機工程學(xué)院 專業(yè)班級： 計算機科學(xué)與技術(shù) D計061班 學(xué)生姓名： 黃 剛 學(xué) 號： 5206111109 指導(dǎo)教師： 巫曉琳(講師) 外文出處：(外文) A personal web page tailoring toolkit for mobile devices 附 件：； 指導(dǎo)教師評語：所選擇的外文資料與畢業(yè)設(shè)計課題密切相關(guān)，反映了ASP應(yīng)用系統(tǒng)開發(fā)的先進理念，學(xué)習(xí)了一些ASP中數(shù)據(jù)庫的開發(fā)技巧與方法。s 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.. Automatic mobile Web page content extractionThe content adapting algorithm we proposed can automatically adapt Web pages to mobile devices. Users always only care about a part of the web content. Content adapting applications should provide a function to extract these parts from a Web page.. Research contributionThis paper discusses the problems encountered and our corresponding solutions. The major contributions of this research are listed below. 1. A crossbrowser configuration tool is designed. 2. The web based nature of our configuration tool allows a user to configure the settings from different puters, and requires no preinstallation of any software.3. Blocks in a Web page can be chosen correctly under the premise that the layout of a Web page does not change frequently.4. A web based management interface is provided.5. An automatic algorithm for mobile Web page generation is proposed.. Outline of this paperThis paper is divided into seven sections. The following is a brief description of the content of each section. In Section 2, an overview of the proposed system and its three major ponents are given. In Section 3, the System design details, problems encountered, and our corresponding solutions are illustrated. Furthermore, we discuss our mobile Web page generation algorithm in Section 4. In Section 5, some tests are conducted to evaluate our system. A practical example showing how to make use of the proposed tool to eliminate unnecessary scrolling is also presented. Several related works are discussed in Section 6. Finally, in Section 7, we make the conclusion and discuss about the future work.2. System design. OverviewBasically, the personalizing process in our Web page tailoring system prises two steps (Fig. 1). First, user must specify his/her preferences of a Web page using a PC or laptop. Second, he/she has to configure the browser on his/her mobile device to go through a specially made proxy, which is responsible for adjusting the content of Web pages according to the preferences set in the first step. Two pictures are given below to illustrate separately the relationship between a user, our Web page tailoring system, and a remote Web server (such as ) in each step.Fig. 2 describes the interaction in the first step. When a user enters a URL in his/her Web browser, a HTTP request is sent to (Line 1) the corresponding Web server specified in the URL. After processing the request by the server, a HTTP response is sent back (Line 1). If the user wants to personalize that page, a program hosted on a tiny Web server included in our system would be downloaded (Line 2) and executed in his/her browser. With the help of that program, the user can specify his/her preferences simply by visual manipulations. After finishing the job, preferences about this page will be sent back and stored in a database for later use (Line 2).Fig. 2. Personalize Web pages using PC or laptop.Fig. 3 pictures the interaction in the second step. Since the user would configure the browser on his/her mobile device to use a proxy included in our system, we would snoop each HTTP request and modify its corresponding response (Lines 3 and 4) in between. For example, if the user visits a Web page that has been personalized before, some actions would be taken to tailor the Web page to meet the user preferences.Fig. 3. Browse Web pages via mobile devices.In order to achieve the above tasks, three ponents are designed in our system: Page Tailor, Configuration Manager, and Mobile Proxy. The purpose and functions of each ponent will be introduced separately. System design details are presented in Section 3.. Page TailorPage Tailor in the form of mobile code can be downloaded and executed in a user39。s browser. Then the Web services exported by Configuration Manager are used by it and Mobile Proxy to access the backend database where user preferences are stor
