Actually OpinionCloud.
It’s a small add-on that allows you to analyze video’s comments. It highlights the keywords that are frequently used. Click on any one of the keyword would enlist all the comments containing the word.
With this add-on we demonstrate and develop new opinion summarization technologies for Web comments on YouTube and Flickr. Popular videos/photos often get up to thousands of comments and in order to get an idea about the crowd’s overall opinion one has to read all of them, which is of course impractical. The OpinionCloud summarization helps to retrieve this important piece of information by generating an opinion word cloud for a given set of comments.
Cool.
