Abstract


With the rapid development of wireless communication technology , it is increasingly urgent want to be able to use a handheld device to facilitate browsing WEB page . But handheld devices because of its small screen and limited computing and storage capacity , making it more difficult to use handheld devices to direct access to ordinary WEB page . To solve this problem , this paper presents a page segmentation cutting solutions . First page standardized processing , followed by page segmentation and noise cleaning , and last pages reorganization . This paper studies mainly focus on the following aspects : First, we compared the pages block algorithm based on the pages of the DOM tree blocking algorithm block algorithm based on visual characteristics of web pages , and location-based relationship . Page segmentation algorithm based on visual characteristics , sub- block granularity is the DoC value preset by the user to determine , which resulted in block granularity is not easy to control the problem . This paper proposed an improved block algorithm based on visual characteristics of web pages , with the sub- block level instead of the DoC value to solve the problems of the original algorithm . Second, the proposed method a use block importance noise cleaning . Block importance considering spatial features and content features of the block , indicating the importance of sub- blocks to reflect the subject content in Web pages marked . The block importance is divided into four levels , the level of the more low-scoring block contains more noise will block important degree of lower-level block deletion approach , we can achieve a clear purpose of the noise . Pages of this paper, sub- block cutting solutions , based on the improved functions based on visual features of pages block technology and based on the block importance marked the noise cleaning technology as the core idea , fusion Web normalized , pages reorganization , and strive cutting technology solutions for handheld device users to provide a WEB page .
