This offers new challenges and opportunities for large-scale text analysis. I argue that social media analytics should be guided by an understanding of how social media language differs from other written language, and why. I will describe a series of studies that document language variation across a number of different social variables. In some cases, social media writing tracks spoken language variation; in other cases, relatively novel \u0022netspeak\u0022 terms like emoticons and abbreviations can also be strongly correlated with demographics and geography. Our recent work concerns language change over time, using a new dataset of hundreds of thousands of authors over nearly three years. Aggregating across thousands of words, we build a unified model of the geographic and demographic factors that drive the spread of words between cities.\u003C\/p\u003E\u003Cp\u003EThis research is in collaboration with David Bamman, Brendan O\u0027Connor, Tyler Schnoebelen, Noah A.
