An unprecedented online data collection project is now underway

An interdisciplinary group of researchers at Northeastern have embarked on an ambitious, multi-million-dollar project to study the way people behave online—and in turn, how the internet behaves back.

Thanks to a $15.7 million grant from the National Science Foundationthe team has begun to recruit volunteers for the online data collection project, which will involve monitoring the online experiences of tens of thousands of volunteer users through a web browser extension researchers are building, then documenting and analyzing the results. When all is said and done, the data collected will be available to scientists around the world and across disciplines for research purposes, as per the foundation’s mandate for the project.

“This is a huge missing piece in the study of the internet,” says David Lazeruniversity distinguished professor of political science and computer sciences, and co-director of the NULab for Texts, Maps, and Networkswho is leading the project.

The money is now being used to build a “National Internet Observatory.”

“The observatory enables a wide range of research concerning the Internet, including examination of the state of the information ecosystem, analysis of damaging online behavior of a variety of types, and generally studies of manifold aspects of the online world,” the researchers wrote in their proposal.

There are numerous research questions spurring the project forward as it relates to these goals, Lazer says. Like to what extent does Twitter, for example, amplify some voices and accounts over others? Or how often does Google point people to high versus low reliability resources?

Researchers also hope to learn more about how information systems and their algorithms enable users to find information—reporting, commentary and other sources—that fit their own ideologies. This is referred to as the “filter bubble” effect, which experts have pointed to as a factor contributing to political polarization and broader social divisions.

An underlying motivation for researchers is to explore and, where possible, disentangle “human and algorithmic choice” on the internet. As it relates, the monitoring project will help researchers gain “insight into what people choose to do” when using social media platforms, “but also what the platforms are doing in return,” Lazer says.

All of this would take place without compromising the personal privacy of the volunteers involved.

Other project collaborators include Christo Wilsonassociate professor of computer sciences; David Choffnesassociate professor of computer sciences and executive director of the Cybersecurity and Privacy Institute; John Baslassociate professor of philosophy at Northeastern; and Michelle Meyer, a bioethicist at Geisinger Health System. Lazer, Wilson and Choffnes are principal investigators on the project.
