Research on Sorting Algorithm for Web Contents

ABSTRACT Text classification is a basic issue in web information processing. The text sorting algorithm is the basic theory for designing and developing classifier in the text classification. In the field of the text sorting algorithm, the most typical sorting algorithms at present include decision tree calculation, Bayes calculation and KNN calculation, etc. This paper discusses the theoretical basis of the above mentioned typical classification algorithms and introduces the applications of those algorithms through analyzing the advantages and disadvantages of each algorithm. At last, the paper presents a kind of realization process for the webpage classifier on the basis of C4.5 algorithm
