Channel 4 'Twitter Tracker'

The 'Twitter Tracker App’ is a 'second-screen' application developed for Channel 4. So far the app has been used for two prime-time shows, 'The Taste' – a 10 part cookery contest featuring Nigella Lawson and 12 would-be chefs, and 'The Jump' – a nightly show in which celebrities compete in a range of winter sports with one unlucky celebrity in each show facing the dreaded Ski Jump.  

The app monitors the twitter ‘buzz’ around contestants and provides sentiment analysis on what is being said about each of them. By tracking tweets which contain both the show’s hashtag and the contestant’s name the app calculates the percentage of total tweets that each contestant has received. This is displayed as a series of circles, each representing a single contestant, which grow or shrink in size depending on the contestant’s share of the buzz.

The app also looks for adjectives in the tweets and displays the top 10 descriptive words relating to each contestant at any point in time. A ‘hot or not’ meter takes the temperature of the sentiment behind the tweets whilst a timeline ‘scrubber’ allows the user to see how the buzz has changed over time since the start of the series.

During transmission of the shows the app was embedded within ‘4Now’, Channel 4’s companion iOS app. It was also available on the show's pages within the main Channel 4 website.
