Proceedings of the 17th Pacific Asia conference on language�…, 2003•aclanthology.orgWe propose and study a new variant of the SVM—the SVM with uneven margins, tailored for
document categorisation problems (ie problems where classes are highly unbalanced). Our
experiments showed that the new algorithm significantly outperformed the SVM with respect
to the document categorisation for small categories. Furthermore, we report the results of the
SVM as well as our new algorithm on the Reuters Chinese corpus for document
categorisation, which we believe is the first result on this new Chinese corpus.

Abstract
We propose and study a new variant of the SVM—the SVM with uneven margins, tailored for document categorisation problems (ie problems where classes are highly unbalanced). Our experiments showed that the new algorithm significantly outperformed the SVM with respect to the document categorisation for small categories. Furthermore, we report the results of the SVM as well as our new algorithm on the Reuters Chinese corpus for document categorisation, which we believe is the first result on this new Chinese corpus.
