 It's a system to help public safety officials understand what's going on during crisis situations by what people are posting on social media. So it's a way for the first responders to actually find out who's in need, where people are without power, where people are flooded through crowdsourcing information that people are posting publicly. The problem that most people face with trying to look at social media is there are thousands of posts coming out of a small area and all of those may not be anything that help you understand what's going on and who's in need. Our data mainly come from Twitter and Instagram. So we're using a free version of their API to get around two percentage of the entire Twitter Firehose API. Around 300 million tweets are posted every day. Two percent is around maybe six million or so. The goal of the project is now to transform it into a tool that's available that first responders can download for their phone and be able to use in a crisis situation.
