Social media is useful for more than just sharing pictures of what you ate for lunch.

By examining geotagged posts on Twitter, researchers at Floating Sheep have been able to construct a map of common racial, homophobic and other discriminatory slurs across the the US.

The map, which is called “Geography of Hate,” builds on a previous project from the research center that shows the locations of racial slurs against President Obama. According to researchers, the purpose of this new project is to better examine the use of social media as a platform for hate:

The prominence of debates around online bullying and the censorship of hate speech prompted us to examine how social media has become an important conduit for hate speech, and how particular terminology used to degrade a given minority group is expressed geographically.

Instead of analyzing the tweets algorithmically based on key words, the researchers are now examining each tweet individually to weed out non-derogatory uses of the words and slurs in question. About 150,000 tweets were flagged and categorized by a group of students from Humboldt State University between June 2012 and April 2013.

The derogatory tweets in any given place are weighted by the total amount of tweets in the area, meaning some results are not what one would expect–Orange County, California produced the most hateful tweets, but its significant amount of Twitter activity in general made it less prominent on the map than other areas.
