Web information service needs a document classification system for efficient management and conveniently searches. Existing document classification systems have a problem of low accuracy in classification, if a few number of feature words is selected in documents or if the number of documents that belong to a specific category is excessively large. To solve this problem, we propose a document classification system using ¡®Modified ECCD¡¯ feature selection method and ¡®Category Weight for each Document¡¯. Experimental results show that the ¡¯Modified ECCD¡¯ feature selection method has higher accuracy in classification than ¥ö©÷ and the ECCD method. Moreover, combining the ¡¯Category Weight for each Document¡¯ feature value and ¡®Modified ECCD¡¯ feature selection method results better accuracy in classification.
