Weiling Wang · Computer Engineering and Applications Journal · 2007
This paper uses vector space model as the description of the Web text,analyses and improves the traditional formula TF*IDF.First,we explore the feature of the Web pages which are written in HTML and describe the situation information of the terms in Web text.Second,we use generalized information theory as the theory base to introduce the quadratic entropy mutual information into the formula.The experiment shows the feasibility and the validity of this method.
