| Abstract(in English) | We have developed a visualization technique for text classification and clustering. First, in this paper, we propose a visualization method for text classification to assist interpretation of the results. In our method, text classification is based on vector-space model, and the multi-dimensional data are mapped on 2D plane. Viewing the 2D maps, the users find typical or unique opinions and correlation of the categories. Second, we also describe the application of the visualization method to text clustering using NMF. |
