| Abstract(in English) | In this paper, we employ the latent Dirichlet allocation as a method for the dimensionality reduction of feature vectors and reveal its effectiveness in document clustering. In the evaluation experiment, we perform clustering on the document sets of Japanese and Korean Web news articles. We regard the categories assigned to each article as the ground truth of clustering evaluation. We compare the clustering results obtained by using the feature vectors whose entries are term frequencies with the results obtained by using the feature vectors whose dimensions are reduced by the latent Dirichlet allocation. |
