Networks Tool Visualization

New network visualization tool maps information spread

Today the Observatory on Social Media and CNetS launched a revamped research tool to give journalists, other researchers, and the public a broad view of what’s happening on social media. The tool helps overcome some of the biggest challenges of interpreting information flow online, which is often difficult to understand because it’s so fast-paced and experienced from the perspective of an individual account’s newsfeed.

Twitter bots play disproportionate role spreading misinformation

UPDATE: This paper is ranked #3 most read among all articles published by Nature Communications in 2018

Analysis by CNetS researchers of information shared on Twitter during the 2016 U.S. presidential election has found that social bots played a disproportionate role in spreading misinformation online. The study, published in the journal Nature Communications, analyzed 14 million messages and 400,000 articles shared on Twitter between May 2016 and March 2017 — a period that spans the end of the 2016 presidential primaries and the presidential inauguration on Jan. 20, 2017. Among the findings: A mere 6 percent of Twitter accounts that the study identified as bots were enough to spread 31 percent of the low-credibility information on the network. These accounts were also responsible for 34 percent of all articles shared from low-credibility sources. The study also found that bots played a major role promoting low-credibility content in the first few moments before a story goes viral.

The science of fake news

The indictment of 13 Russians in the operation of a “troll farm” that spread false information related to the 2016 U.S. presidential election has renewed the spotlight on the power of “fake news” to influence public opinion. Now, an Indiana University faculty member who studies the spread of misinformation online is joining prominent legal scholars, social scientists and researchers in a global “call to action” in the fight against it. Filippo Menczer, a professor in CNetS and the IU School of Informatics, Computing and Engineering, is a co-author of a paper published March 8 in the journal Science that calls for a coordinated investigation into the underlying social, psychological and technological forces behind fake news. This is necessary to counteract the phenomenon’s negative influence on society, the authors said. READ MORE

DARPA grant to study information spread

geo-homophilyFil Menczer, professor of computer science and informatics at the School of Informatics, Computing, and Engineering, is part of a group that has been awarded a $1.2 million grant from the Defense Advanced Research Projects Agency (DARPA) to study how and at what rate information spreads in a global information environment. The project, COSINE: Cognitive Online Simulation of Information Network Environments, also involves Professor of Informatics Alessandro Flammini and Assistant Professor of Informatics and Computing YY Ahn. The project is in collaboration with colleagues at the USC Information Sciences Institute (ISI) and the University of Notre Dame. Read more…
