While most people would not declare their intention to get into a fight, tweets with words like "drunk" or "wasted" might be able to predict an assault.
A research paper published in the scientific journal Decision Support Systems last month says tweets can help anticipate 19 to 25 types of crimes especially in cases of stalking, theft and gambling.
Researcher Matthew Gerber used public tweets that were geo-tagged in Chicago, and compared the tweets to the city’s crime database.
"So if I tweet about getting drunk tonight, and a lot of people are talking about getting drunk, we know there are certain crimes associated with those things that produce crimes. It's indirect," Gerber said in an interview with AFP.
In other words, if gobs of people are talking about getting inebriated, there could be an increase in crime, since drinking can cause folks to do stupid things.
The study hopes that the results can "improve the allocation of scarce resources such as police patrols and officer time, leading to a reduction in wasted effort and decrease in crime response times."
