| Abstract(in English) | In this paper, we extract some similar documents from large number of text documents by calculating eigenvector of document-term similarlity matrics. Namely, we propose a Weighted-SR (WSR) method based on the Spectral-Relaxation (SR) method. The SR method is one of core extraction methods of complex networks. We also consider LSA-WSR and MDS-WSR methods based on LSA and MDS. In our experiments using a text document dataset from Yahoo! News, We demonstrate that these methods extract documents which consist of mixed topics and split one topic into some core portions. We also show that the number of extracted documents is decreased and similar documents narrowed down by increasing η which is an arbitrary parameter. |
