Big Data Chalk & Talk/Brown Bag: Jacob Eisenstein

Primary tabs

Four Georgia Tech research hubs have launched a new “chalk & talk” brown bag lunch series on Big Data. The weekly series, sponsored jointly by the Institute for Data & High Performance Computing (IDH), Institute for Materials (IMaT)Center for Data Analytics (CDA) and Center for High Performance Computing (HPC) will be held on most Thursdays during the Fall and Spring Semesters and feature a mix of topics, including those related to big data for materials and manufacturing, as well as other topics critical to the broader area of big data.

All meetings are held on Thursdays during lunchtime. 

Date: February 6
Topic: "Understanding Language Variation in Social Media"
Presenter: Jacob Eisenstein

Abstract:

An increasing amount of informal communication is conducted in written form, through computer-mediated channels such as social media. 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 "netspeak" 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.

This research is in collaboration with David Bamman, Brendan O'Connor, Tyler Schnoebelen, Noah A. Smith, Eric P. Xing, and Yi Yang.
