Dirk Hovy to Analyze Toxic Behavior on Twitter

THE ASSOCIATE PROFESSOR IS PART OF AN INTERDISCIPLINARY TEAM THAT WON A GRANT FUNDED BY THE SOCIAL PLATFORM

Dirk Hovy, a computational sociolinguist and Associate Professor at Bocconi’s Department of Marketing, is part of an interdisciplinary team that won a Twitter Research Grant aimed at assessing and improving the quality of the conversation on the social platform. Twitter assigned two grants out of more than 230 research proposals.
 
Led by Rebekah Tromble, Assistant Professor of Political Science at Leiden University (Netherlands), the team includes scholars from Syracuse University, Delft University of Technology, and Bocconi University. They will conduct research comparing discussions around polarized and non-polarized topics in the United States and United Kingdom to develop and implement four metrics that will provide a better understanding of how communities form around discussions on Twitter and will investigate the extent of certain problems that may develop in those discussions. The team brings together scholars with different backgrounds and expertise, bridging political science, communication, and computer science to develop metrics and conduct experiments aimed at identifying potentially problematic behaviors on Twitter.
 
"I am extremely excited to be part of a such a unique collaboration between social and technical sciences on a project of this importance to society”, Prof. Hovy says. “Working across disciplines will enable unparalleled insights into healthy online conversations, and collaborating with Twitter means we can analyze authentic source data at an unprecedented scale".
 
 “The last few years have made it clear that if we are going to effectively identify, evaluate, and address some of the most difficult problems on social media, academic researchers and tech companies will need to work together much more closely. This initiative presents an important and promising opportunity for such collaboration”, Prof. Tromble says.
 
The project focuses on two challenges faced by Twitter. The first is the presence of echo chambers – that is, the extent to which discussions are enclaved in homogeneous, and often polarized, groups. "When people are unaware of others' points of view, they have informational blind spots. This problem is aggravated online, because people are more likely to access content that is tailored to their preferences and interactions. While we have some evidence that filter bubbles and echo chambers are a problem on Twitter, one of this project's contributions will be to empirically understand the extent and severity of the problem", explains Nava Tintarev, Assistant Professor at Delft University of Technology (Netherlands), whose work will focus on developing and implementing computational techniques to assess the diversity of perspectives on Twitter.
 
The second area of research will explore uncivil and intolerant discourse. These metrics will examine the extent to which those who participate in Twitter discussions engage in toxic behaviors. "Political discussion online is often dismissed due to uncivil discourse, and because of that we are sometimes unable to understand its true value. Rather than lumping all problematic discourse into a single category, we distinguish between uncivil and intolerant statements. Incivility online might serve an important and valid purpose in discourse, while intolerance is, by its nature, threatening to democracy", explains Patricia Rossini, postdoctoral researcher at Syracuse University (United States), whose work focuses on understanding such discourse online.
 
The team also counts the expertise of Michael Meffert, Assistant Professor in Political Science at Leiden University, who will be responsible for leading experimental design, implementation, and analysis, and Jennifer Stromer-Galley, Professor in the School of Information Studies at Syracuse University, whose expertise in political communication and social media will provide support to the conceptualization, development, and implementation of Twitter health metrics.
 
As part of the research grant, the team will work closely with Twitter. While scholars will have the autonomy to develop and publish research under this grant, the outcomes of this project will help inform Twitter's future policies and practices to promote a healthy conversational environment.
