Texas educators work to use tech to fight fake news

- By Loyd Brumfield The Dallas Morning News

“We’re not talking about the (Donald) Trump definition of fake news. Trump’s definition of fake news is CNN, The Washington Post, The New York Times. We’re talking about the pre-Trump definition—stories that have been intentiona­lly passed around with the intent to mislead.” —Mark Tremayne, UT-Arlington assistant professor of communicat­ions

ARLINGTON, Texas— Incensed by what he thought was a pedophilia ring headquarte­red in a Washington, D.C., pizza restaurant, a 28-year-old man opened fire inside Comet Ping Pong Pizza last year, sending employees and customers scrambling for cover.

The Dallas Morning News reports the shooting was real, but the sex ring—supposedly overseen by 2016 Democratic presidenti­al candidate Hillary Clinton—was not. Instead, it was propaganda passed off as authentic through social media feeds and rightwing websites.

No one was hurt in the Dec. 4 shooting, and the suspect was sentenced in June to four years in prison.

Because of incidents like that one, a group of college instructor­s in North Texas believes combating fake news is a matter of national security. They’re working on a proposal that would use technology to help root out false claims in the news.

“We decided to make national security the focus because of the potential interferen­ce in our election coming from Russia,” said Chengkai Li, a University of Texas at Arlington associate professor in the Department of Computer Science and Engineerin­g.

Li and four others—two professors from UTA and two from the University of Texas at Dallas—are collaborat­ing on a project titled “Bot vs. Bot: Automated Detection of Fake News Bots,” and they have a one-year grant of $30,000 in seed money from the University of Texas at Austin’s Texas National Security Network Excellence Fund to get started.

“This is a seed grant that we hope will lead to a much larger grant that will identify these bots for social media users,” Li said. “Right now, you don’t know what is coming from a real person and what’s coming from a computer, sometimes for malicious, or at least, misleading reasons.”

Previously, Li and other colleagues partnered with Stanford and Duke universiti­es to develop ClaimBuste­r, a fact-checking service developed from a $241,778 grant from the National Science Foundation. ClaimBuste­r works by letting users type in what they’ve heard in the news, and the results will produce a sliding scale of accuracy. The lower the number, the less accurate the reports.

The site also has transcript­s of all the 2016 presidenti­al debates and heavy documentat­ion of its methodolog­y.

Li and his computer science/engineerin­g colleague Christoph Csallner will apply data mining techniques, coding analysis and other security measures to design an algorithm to spot fake news, with an assist from Mark Tremayne, an assistant professor of communicat­ion, and others who come from a journalism background.

UTD associate professor of computer science Zhiqiang Lin and Angela Lee, UTD assistant professor of emerging media and communicat­ion, are also part of the project.

The joint effort between the two universiti­es will focus on false accounts spread via Twitter.

“We’re not talking about the (Donald) Trump definition of fake news,” Tremayne said. “Trump’s definition of fake news is CNN, The Washington Post, The New York Times. We’re talking about the pre-Trump definition—stories that have been intentiona­lly passed around with the intent to mislead.”

The researcher­s in North Texas aren’t the only ones seeking to identify purveyors of phony informatio­n. Melissa Zimdars, an assistant professor of communicat­ion at Merrimack College in Massachuse­tts, developed a checklist of fake news sites shortly after Trump defeated Clinton in the November election.

“I think the most troubling aspect of fake news and the proliferat­ion of misleading informatio­n is that it further destabiliz­es the relationsh­ip between individual­s and the press as well as between individual­s of different political ideologies,” she said.

Zimdars created her checklist for her students after she kept running across false sources cited in their papers. She also realized that even some of her profession­ally trained colleagues couldn’t tell the difference between credible news sources and misleading ones.

She temporaril­y took down her checklist after she became the target of harassment, Zimdars said, but made it public again after the attacks against her eased.

It remains a live document, but Zimdars no longer updates it. It includes more than 1,000 sources that spread malicious or unreliable informatio­n, were satirical or relied on clickbait headlines to capture attention.

“There are plenty of actual things about which to disagree without having to consider alternativ­e truths in the equation,” Zimdars said. “How can we function as a society if we’re not even sharing or at least understand­ing some of the same reality?”

Zimdars said readers can get a head start on spotting fake news sites by looking at domain names, such as the “8006” that appears at the end of an otherwise legitimate-looking fake New York Times site, or a “co” that comes after “.com” on sites that otherwise borrow the names of legitimate news outlets.

Li and his partners aren’t sure what shape their program will eventually take.

“One form can be a browser plug-in that can tell you something about the truthfulne­ss of something, or it could be a third-party bot or an app or something,” Li said.

If the yearlong period ends and the grant isn’t renewed, Li said the team will continue to work on the project in classrooms and laboratori­es.

Research will really start to take shape when students return in the fall, Tremayne said. The group is considerin­g organizing a “hack farm” as a way to attract students to the project.

“The idea is, can we come up with some code to identify fake news bots?” Tremayne said. “Even if it just means something like throwing ideas at the wall and seeing if anything sticks.”
