Invited Talk Abstracts

When NLP meets language variation
Dong Nguyen, Assistant Professor, Information and Computing Sciences, Utrecht University

There are often various ways to express the same thing. Think of, for example, the different words we can use for a given concept, or the many creative spellings in social media. Language variation is often seen as a challenge for developing robust NLP models. In this talk I will reflect on what NLP and sociolinguistics have to offer each other. In particular, I will focus on how language variation is not just a problem to be solved, but also an opportunity to explore exciting questions about language and social behavior and to develop NLP models that are sensitive to social context.

How (and Why) Online Dating Experiences Differ across American Cities
Elizabeth E. Bruch, Associate Professor in Sociology and Complex Systems, University of Michigan

Social scientists have long shown that city-level differences in patterns of assortative mating, marriage rates, and non-marital childbearing are associated with labor market conditions and partnering opportunities. But it is difficult to observe the interactions that give rise to romantic outcomes in different places. As a result, we know little about whether, how, and why romantic experiences differ across cities. In this talk, I present results from a new study that uses rich activity data from a large, U.S. dating website to explore how population composition interacts with mate-seeking behavior to shape men and women's online romantic experience. Building on insights from psychology and behavioral ecology, I focus on two distinct classes of behavior: choice/preferences and competition. I show that mate seekers in different U.S. cities have divergent strategies for mate pursuit: they differ in their preferences, pickiness, and intensity of competition. In the final section, I focus on individuals who appear to change markets, to assess whether and how changing contexts is associated with a change in strategies for mate pursuit. This study represents a novel quantitative effort to show how men and women's mate-seeking behaviors differ systematically with their opportunities.

Measuring Group Differences in High-Dimensional Choices: Method and Application to Congressional Speech
Jesse Shapiro, Eastman Professor of Political Economy, Brown University

We study the problem of measuring group differences in choices when the dimensionality of the choice set is large. We show that standard approaches suffer from a severe finite-sample bias, and we propose an estimator that applies recent advances in machine learning to address this bias. We apply this method to measure trends in the partisanship of congressional speech from 1873 to 2016, defining partisanship to be the ease with which an observer could infer a congressperson’s party from a single utterance. Our estimates imply that partisanship is far greater in recent years than in the past, and that it increased sharply in the early 1990s after remaining low and relatively constant over the preceding century.

Persuasion, Bias, and Choice? Building Socially-aware Language Technologies
Diyi Yang, Assistant Professor, Interactive Computing, Georgia Institute of Technology

Over the last few decades, natural language processing (NLP) has had increasing success and produced industrial applications like search, and personal assistants. Despite being sufficient to enable these applications, current NLP systems largely ignore the social part of language, e.g., who says it, in what context, for what goals.  In this talk, we take a closer look at the interplay between social signals and computational methods via three works. The first one studies what makes language persuasive by introducing a semi-supervised neural network to recognize persuasion strategies in good-faith requests on crowdfunding platforms. We then describe our neural encoder-decoder systems to automatically transform inappropriately subjective or unwanted framing into a neutral point of view. The last part demonstrates how conversation stages and topics can be utilized to generate better summaries for everyday interaction.


Accepted Papers

See the official Proceedings of the Fourth Workshop on Natural Language Processing and Computational Social Science at the ACL Anthology for all published papers, talk videos, and supplementary materials!

Below lists information about paper presentations during the workshop itself. Its listing also non-archival papers, which are not in the proceedings.


Virtual Poster Session

See the list of papers on Virtual EMNLP to access papers' 5-minute pre-recorded videos, and PDFs of the papers themselves. Authors will be available to discuss the papers during the two virtual poster sessions, which will take place on GatherTown. You are encouraged to view some videos beforehand, but if you can't, authors are encouraged to discuss them anyway!

How to find it: Inside GatherTown, click "Calendar" in the right sidebar, find the "NLPCSS Poster Session" entry in the list, then click it to get directions to the workshop room - it'll be rooms F and G. (Screenshot)

The papers are divided into two sessions - authors should be available to discuss during their session. They certainly can be available in the other one too, if they wish - the virtual "poster" signs are supposed to be there the whole time.


Session 1 (at 16:00 UTC):


Session 2 (at 19:45 UTC):
