A New Statistical-based Method in Automatic Text Classification

LIU Bin 1 HUANG Tie jun 2 CHENG Jun 3 GAO Wen 1 (1 Institute of Computing Technology Chinese Academy of Sciences Beijing 100080 2 Grduate School of Chinese Academy of Sciences Beijing 100080 3 The Library of Chinese Academy of Sciences Beijing 100080 China)  
Automatic text classification is defined as the task to assign pre defined category labels to documents.To improve the classification performance,this article puts forward the multi level feature selection method and the kernel based distance weighted KNN algorithm.We extract the statistical text features on three different levels as Chinese letters,the common wordlist and the professional wordlist,which can represent more statistical character of the document set.The kernel based weighted KNN algorithm solves the multi peak distribution problem and the overlap boundary problem of the sample set,as well as the classifier's precise decision problem.In practical use,the Internet and text data bases provide many pre classified training samples.But some of them are not good for training the classifier.We use sample weightiness analysis to address this problem.The experimental system shows the effectiveness of the method.
