Using Zero Anaphora Resolution to Improve Text Categorization
Ching-Long Yeh, Yi‐Chun Chen · Institutional Repositories DataBase (IRDB) · 2003
In Chinese, anaphors are frequently omitted, termed zero anaphor (ZA), from text due to their prominence. Thus the information carried by ZAs in text can not be used to contribute the calculation of text categorization. In this paper, we employ a ZA resolution method to recover the omissions of anaphors in text. Then the resulting text is used as the input of a text categorization system. The experiment result shows that ZA resolution method enhances the accuracy of text categorization from 79 % to 84%. 1
