KeyGraph for Visualization of Discussions in Comments of a Blog Entry with Comment Scores

This paper discusses a new application of KeyGraph for visualization of discussions in comments of a blog entry in Slashdot. KeyGraph is a visualization tool for discovery of relations among text-based data. A common approach of applying KeyGraph is that of applying it to the whole data at once. In this paper, we propose an approach that applies KeyGraph successively to multiple chunks of comments, each chunk having a different range of moderation scores provided by Slashdot. This approach gives a higher number of scenarios with more specific meaning than the common approach. In addition, compared with comment summaries composed by human subjects, the resulting scenarios effectively summarize discussions in the comments.
