Lillian Lee Cornell University Title: Analyzing phrasing effects via found conversations: 'Parallel universes' in Twitter, ChangeMyView, and the Fed (FOMC) Abstract: This talk will focus on the effect of phrasing, emphasizing aspects that go beyond just the selection of one particular word over another. The issues we'll consider include: Does the way in which something is worded in and of itself have an effect on whether it is remembered or attracts attention, beyond its content or context? Can we characterize how different sides in a debate frame their arguments, in a way that goes beyond specific lexical choice (e.g., "pro-choice" vs. "pro-life")? The settings we'll explore range from posts that do or do not catch on in Twitter, to arguments that persuade in the ChangeMyView subreddit, to language that affects discussion points among members of the Federal Open Market Committee (FOMC). Joint work with Cristian Danescu-Niculescu-Mizil, Vlad Niculae, Bo Pang, and Chenhao Tan.
