YU Min-min · Jisuanji gongcheng · 2011
Existed main text localization methods in webpage information extraction technologies only consider the text information.Those methods lead to low accuracy when main text contains a few text information and abundant image information.In order to solve this problem,this paper designs a method to estimate the image information and image effective information based on information theory,and presents a novel algorithm for main text of webpage localization based on image and text effective information.Experimental results show that on different main text ratio,this algorithm has higher accuracy.
