Tweetviz is an interactive tool to help businesses extract actionable information from a large set of noisy Twitter messages. Tweetviz visualizes the tweet sentiment of business locations, identifies other business venues that Twitter users visit, and estimates some simple demographics of the Twitter users frequenting a business. Tweetviz was demoed at SIGIR 2016 (Sijtsma, Qvarfordt and Chen, 2016). The video describes the project Tweetviz is part of.
