Our current visualization shows the count of liberal inlinks to a news article as a blue “wing” on the left, and the number of conservative inlinks as a red “wing” on the right. The emotional charge of the discussion around the news link is shown as a “heat indicator” on the outside of the wings. Emotional charge ranges from a single orange square to four white-hot squares. Clicking on the wings produces a dropdown of the individual blog posts linking to the news article. In the dropdown, emotionally charged posts have a fuzzy border, while emotionally neutral posts have a solid border.
The data we mine in the Blews system is provided by the LiveLabs Social Media Platform. We consume the blog feed from that platform and first identify political (liberal/independent/conservative) blog posts. From those posts, we extract links to news articles and the text in the posts that surround the news links. We apply a classifier to that text, determining the emotional charge. The data is then imported into our database, and the news articles are crawled. We also apply a duplicate detection algorithm to the news articles, in order to detect stories that contain the same syndicated content or are linked to through diffent URLs. Finally, the content of the database is aggegated and visualized.
