| Abstract(in English) | The co-occurrence vectors that are the co-occurrence frequencies between words and semantic attributes in a corpus reflect the semantic similarities between words. This paper shows that words of superordinate or subordinate or sibling concept at various levels are associated by applying α-divergence that is the distance measure to which Kullback-Leibler Metric is expanded as the distance measure between co-occurrence vectors. Moreover, it describes the application of α-divergence between co-occurrence vectors to the document classification. |
