Hope to see you there!
Brendan O'Connor (CMU/Harvard): Text Data Analysis in Political Science and
What can text analysis tell us about society? Enormous corpora of news, social
media, and historical documents record events, beliefs, and culture. While
manual content analysis is a useful and established social science method,
interest in automated text analysis has exploded in recent years, since it
scales to massive data sets, and can assist in discovering patterns and themes.
I will present two case studies of using text analysis as a measurement
instrument for social phenomena: (1) Extracting events between international
actors from news text, using temporal and dyad political context as a prior for
learning latent event classes; and (2) Examining Twitter to answer questions
about how language changes -- what are the geographic and demographic
determinants linguistic influence? Recurring themes include language analysis
as a statistical indicator of population-level variables, and latent state
temporal modeling of textual time series.
Given time and audience interest, I'm also happy to talk about syntactic
analysis of social media text, sentiment analysis and opinion polls, or
analyzing Chinese censorship in microblogs.
