Are you drinking while tweeting? This algorithm can tell

Tweeting under the influence may not get you in as much trouble as drunk driving does, but it can still mean a whole lot of hot water. Now there's an algorithm that can tell when you're drinking while tweeting -- and also figure out where you're imbibing. Using machine learning, researchers at the University of Rochester have created a system that can find alcohol-related tweets and determine whether they were made by someone who was actually drinking at the time. It can also pick out whether those tweeters were drinking at home or somewhere else. Equipped with that knowledge, the researchers compared the results for different locations in New York State. Eventually, they hope to use the technology to study the health implications of alcohol.
