Description:
TweetTracker is a web application developed by Arizona State University, Phoenix USA. It is a tool to track, analyse and understand activity on Twitter. This enables emergency responders to search and track the population's tweets about specific disasters or events geographically. This contributes to the emergency responders insight into the situation, and may be used as information for necessary actions. The system analyses Twitter feeds to extract and rank popular hashtags, mentions and URLs. It can also provide time filters, geographical maps for tagged tweets and word clouds for popular terms. The TweetTracker is similar to the web application Ushahidi, which applies the same techniques but instead of focusing only on disasters, they focus on a wider scale of events.
