【摘要】：随着移动通信技术的快速发展和移动终端上网便捷性的不断提高,移动终端已经超越PC成为人们访问互联网资源的主要终端设备。然而当使用移动终端访问专为PC设计的Web页面时,页面布局的不合理、噪声信息多、用户体验差等适配问题,给用户浏览带来了很大的不便。如何将原有的Web页面转换为适合移动终端浏览的页面,为移动端用户提供快速、具有良好用户体验的浏览服务有着重要的意义。本文的研究目的是给出一种将传统Web信息系统平滑迁移到移动平台的应用解决方案,并开发一套通用型适配系统。该方案以微信公众平台作为移动端信息展现平台,采用页面转换技术对原Web页面进行分割、信息提取以及重新排版,将原页面转换为适合用户在移动端浏览的页面,同时结合页面缓存技术,实现Web信息系统的微信平台迁移。论文首先对适配系统中的页面转换技术进行了研究。提出了基于DOM树的网页信息抽取算法,通过信息抽取将网页的主题内容与噪音内容分离开来,然后对抽取出的内容进行重组,完成适配。考虑到网站内的网页通常是由一个或多个模板生成,同一模板构建的网页风格相似,为加快信息抽取,设计了基于网页分割的网页信息抽取模板生成算法。针对信息抽取模板生成过程中的关键问题网页结构相似性度量,为提高聚类的准确度,提出一种改进的基于子树匹配的网页结构相似性度量算法。其次,采用Java语言设计实现了适配系统。系统分为基础服务和适配服务两个部分,包括页面模板库生成、页面转换以及页面缓存等功能模块。页面模板库生成模块首先对Web网站的站内页面进行抓取,并根据网页结构相似性对抓取的网页进行分类,然后对每一类网页生成相应的页面信息抽取模板,页面转换模块则根据被处理网页是否有匹配的页面信息抽取模板而做出相应的转换处理。适配系统中还加入了页面缓存模块,以提高对重复请求的响应速度,进而提升系统的处理性能。通过实际网站的测试表明,本文所开发的系统可自动完成网页在移动端的适配转换,转换后的页面内容显示准确合理,页面排版良好,并且可根据不同的屏幕尺寸自动调整布局。系统实现了Web信息系统移动端的迁移,并且运行稳定,处理性能良好。
[Abstract]:With the rapid development of mobile communication technology and the increasing convenience of mobile terminals, mobile terminals have become the main terminal equipment to access Internet resources. However, when the mobile terminal is used to access the Web page designed for PC, the unreasonable layout of the page, the many noise information, the poor user experience and so on bring great inconvenience to the user browsing. How to convert the original Web pages into pages suitable for mobile terminal browsing is of great significance to provide mobile users with fast browsing services with good user experience. The purpose of this paper is to provide an application solution for smooth migration of traditional Web information system to mobile platform and to develop a general adaptation system. The scheme takes the WeChat public platform as the mobile information display platform, uses page conversion technology to segment, extract and rearrange the original Web pages, and converts the original pages into pages suitable for users to browse on the mobile side. At the same time, the migration of Web information system based on WeChat platform is realized by using page caching technology. In this paper, the technology of page conversion in adaptation system is studied. A Dom tree based information extraction algorithm is proposed, which separates the topic content from the noise content, then reorganizes the extracted content to complete the adaptation. Considering that the web pages in a website are usually generated by one or more templates and the web pages constructed by the same template are similar in style, in order to speed up information extraction, a page information extraction template generation algorithm based on web page segmentation is designed. In order to improve the accuracy of clustering, an improved similarity measurement algorithm based on subtree matching is proposed to solve the key problem in the process of generating template for information extraction. Secondly, the adaptation system is designed and implemented by Java language. The system is divided into two parts: basic service and adaptation service, including page template library generation, page conversion, page cache and other functional modules. The page template library generation module firstly grabs the pages in the Web site and classifies the captured pages according to the structural similarity of the web pages, and then generates the corresponding page information to extract the template for each kind of web pages. The page conversion module extracts the template according to whether there is a matching page information and makes the corresponding conversion processing. A page cache module is added to the adaptation system to improve the response speed to repeated requests and improve the processing performance of the system. The test of the actual website shows that the system developed in this paper can automatically complete the adaptation conversion of the web page on the mobile side, the page content after the conversion is accurate and reasonable, and the page layout is good. And can adjust the layout automatically according to the different screen size. The system realizes the migration of the mobile end of the Web information system, and runs stably and has good processing performance.
