Simon Cowell and Randy Jackson have been judges since the show first aired. In 2009 Kara Dio Guardi joined the panel with comedian Ellen De Generes making a panel of 4 judges in 2010.12 contestants in the show with a different theme & celebrity mentor each week, critiqued by a panel of judges followed by a public phone in/text in vote within a specified time limit after which the contestant with the lowest votes is eliminated.Celebrities are paired with dance experts (mentors) and perform one dance a week.But for this project â€“ an effort to get its own buzz on for its technology by applying it to the TV shows that some 50 million Americans are addicted to â€“ it’s home-grown tech to ferret out the positive/negative/neutral sentiment among the data it’s harvesting from Twitter, Facebook, blogs, and forum discussions.Kapow’s laid over that some more complex algorithms it’s developed to try to understand how strong sentiment is and what that actually might equate to in the results.
Kapow’s heritage is in enabling companies through its robots to automatically get data for analyzing everything from markets to competitors to pricing to customer opinions, whether it’s from web services like Twitter or Facebook where all or lots of data is publicly available, or from more difficult-to-access sources, such as sites that use Flash-based maps that don’t render in HTML or information behind password-protected accounts that would otherwise require API access and code-writing.With Kapow’s background, extracting the social media commentary around these two shows is easy for its technology (though of course it can’t mine private updates in services like Facebook) — it takes only about an hour to get up and running a robot to monitor new blogs or other sites that reflect our national pastime of voting on dancers and singers, Kawamura says. And once the information with these references is in its database, Reality Buzz can apply semantic analysis of keywords in relation to each other in search of the positive, negative or neutral nuances relative to them.“The easy part is to immediately filter in the positive, negative, and neutral and graph who has more positive vs. But you can’t come to any solid conclusions just on the basis of a graph, and that’s where things get interesting â€“ just as they do in applying sentiment analytics to business concerns.The couple receiving the lowest combined total of judges' points and audience votes is eliminated each week until only the champion dance pair remains.Tom Bergeron has been the host since the program's premiere in 2005. She was replaced by Samantha Harris for seasons 2 through 9 (2006–09), who was then replaced by Brooke Burke-Charvet from seasons 10 through 17 (2010–13).
