In order to understand the trend of social bookmarking with respect to the huge number of web pages in the same category, "Bookmark Visualizer," is proposed. The Bookmark Visualizer merges the three dimensional data sets of huge number of web pages to suitable size by using hierarchical clustering, and plot the obtained data as the single graph. In experiments using social bookmarking data extracted from eight categories on HatenaBookmark (May 2nd, 2009), it is confirmed the effectiveness of the proposed system.
