Indiana University Computer Scientists Develop Tool for Uncovering Bot-Controlled Twitter Accounts

May 6, 2014 by Gary Price

The following info tool comes from Indiana University’s Truthy information diffusion project
From Indiana University:

Complex networks researchers at Indiana University have developed a tool that helps anyone determine whether a Twitter account is operated by a human or an automated software application known as a social bot.
[Our emphasis] The new analysis tool stems from research at the IU Bloomington School of Informatics and Computing funded by the U.S. Department of Defense to counter technology-based misinformation and deception campaigns.
BotOrNot analyzes over 1,000 features from a user’s friendship network, their Twitter content and temporal information, all in real time. It then calculates the likelihood that the account may or may not be a bot. The National Science Foundation and the U.S. military are funding the research after recognizing that increased information flow — blogs, social networking sites, media-sharing technology — along with an accelerated proliferation of mobile technology is changing the way communication and possibly misinformation campaigns are conducted.

“We have applied a statistical learning framework to analyze Twitter data, but the ‘secret sauce’ is in the set of more than one thousand predictive features able to discriminate between human users and social bots, based on content and timing of their tweets, and the structure of their networks,” said Alessandro Flammini, an associate professor of informatics and principal investigator on the project. “The demo that we’ve made available illustrates some of these features and how they contribute to the overall ‘bot or not’ score of a Twitter account.”
Through use of these features and examples of Twitter bots provided by Texas A&M University professor James Caverlee’s infolab, the researchers are able to train statistical models to discriminate between social bots and humans; according to Flammini, the system is quite accurate. Using an evaluation measure called AUROC, BotOrNot is scoring 0.95 with 1.0 being perfect accuracy.
[Clip]
The team received just over $2 million in 2012 for a proposal called “Detecting Early Signature of Persuasion in Information Cascades” and last month presented results about BotOrNot and other aspects of the project at a Department of Defense meeting in Arlington, Va.
