Upstate researchers have found a way predict the likelihood of getting sick after visiting a particular restaurant. The system is called Nemesis and monitors tweets made by restaurant patrons on the popular social media website, Twitter. It then detects likely cases of foodborne illness in close to real-time.
Many people tweet on devices that are GPS enabled, and Nemesis uses this to figure out which restaurant they ate at. It continues to track their tweets for 72 hours after a restaurant visit, to detect whether or not they’ve become ill.
