| Abstract(in English) | Most of conventional text classification methods use symmetric measures such as cosine similarity or Euclidean metric of feature vectors derived from documents. This paper introduces to use Kullback-Leibler metric, which is non-symmetric, of the vectors for the text classification. We found that Kullback-Leibler metric instead of cosine similarity can reveal different aspect of association between words. Considering this property, this paper proposes the combined classification method which uses both cosine-Euclidean measure and KL metric. The experimental results showed that the proposed method improves classification accuracies of the method using only the cosine-Euclidean measure. |
