Abstract: By analyzing the factors which affect user perceived latency, a method is presented that allows the viewers of Web sites to build their own personalized portals, using specific thematic areas of their preferred Web sites. This method is based on an algorithm which fragments a Web page in discrete fragments with pages’ internal structure. The method can efficiently reduce the response time and improve user satisfaction in the limited network bandwidth and the rising of network flow over network.

摘要： 在分析影响用户感知时间的诸多因素基础上，针对网络带宽一定、网络绝对流量增加的情况，从门户网站页面的静态表现结构多半由一些相对独立的区域（主要是Table tags分割的一些区域）构成这一特点出发，研究了通过页面分解技术构建个性化门户网站用以缩短Web网站对用户click的响应时延，从而提高用户满意度。
