| Abstract(in English) | In order to extract topic changes of news themes from a set of news articles, relationships between articles are analyzed from both quantitative and qualitative aspects, based on Topic Structure Graph. First, the quantitative analysis proves that similarity calculation at the level of Topic Structure Graph can express the strength of relationships between the articles more precisely than similarity calculation at the level of keywords. Second, the qualitative analysis categorizes the common keywords between the articles based on node degree and gives the sense of relations between the articles. Finally, based on these results, we proposed a method of extracting word-centric topic changes of news themes. |
