We present a method for producing a bird’s-eye view of statements that are ex- pressed on Web pages on a given topic. This method aggregates statements that are relevant to the topic, and shows con- tradictory and contrastive relations among them. This view of contradictions and contrasts helps users acquire a top-down understanding of the topic. To realize this, we extract such statements and re- lations, includingcross-documentimplicit contrastive relations between statements, in an unsupervised manner. Our experi- mental results indicate the effectiveness of our approach.
