Abstract: With the development of the smart home,a great number of TV-user oriented Web applications are developed.Since the users interact with the television by remoter,the browsing cost of the webpage is affected by its layouts.What’s more,the simplifying of the elements on the webpage makes the automatic optimizing possible.In this paper,we proposed an algorithm to calculate the browsing cost for different kinds of interactions.Considering the elements’ types,positions,sizes,and structures,we proposed an interchangeability estimate algorithm to check out whether the two elements can change their positions with each other.On the basis of the two mentioned methods,we proposed an automatic webpage refactoring which gives each element a weight from the visits of the users and refactoring the webpage in order to reduce the total browsing costs.The technique was tested on a website which consists 116 pages to test the correction and significance of the method.

Key words: Webpage refactoring,Browsing cost,Interchangeability estimate,Webpage optimizing
