The screen shot below is from a live QlikView application we ran during the QlikView 2014 Event in Orlando which tracked all Tweets containing the hashtag #qonnections.

The application also scored these Tweets for sentiment and looked up the Klout score for all the Tweeters.

The application was built in about 30 minutes as explained in this blog post.

We also ran a similar dashboard for other events which you can find here.
