The University of Texas at Austin School of Information Associate Professors Matthew Lease and Kenneth R. Fleischmann have been awarded a $150,000 grant from the Micron Foundation for a two-year project, “Tackling Misinformation through Socially-Responsible AI". In addition to Lease and Fleischmann, the project team includes Associate Professor Samuel Baker (English), Associate Professor Natalie Stroud (Communication Studies), and Professor Sharon Strover (Radio-TV-Film).

Socially-responsible artificial intelligence (AI) involves designing AI technologies to create positive societal impacts. “Emerging AI technologies create tremendous potential for both good or harm,” wrote the research team. “We cannot simply assume benign use, nor can we develop AI technologies in a vacuum ignoring their societal implications.” However, how does an abstract goal like socially-responsible AI get implemented in practice to solve real societal problems? “We argue that grounding the pursuit of responsible AI technology in the context of a real societal challenge is critical to achieving progress on responsible AI,” the team writes, “because it forces us to translate abstract research questions into real, practical problems to be solved.”

Grounding the pursuit of responsible AI technology in the context of a real societal challenge is critical to achieving progress on responsible AI.

In particular, the team will pursue socially-responsible AI to tackle the contemporary challenge of combatting misinformation online. While recent AI research has sought to develop automatic AI systems to predict whether online news stories are real or fake, “why should anyone trust a black-box AI model telling them what to believe”, the team asks, “when many people distrust even well-known news outlets and fact-checking organizations? How do people decide ― if it is a conscious and rational choice ― to believe or even circulate what is actually misinformation? How can AI systems be designed for effective human interaction to help people better decide for themselves what to believe?”

The project team brings diverse, relevant expertise and prior work experience on socially-responsible AI and online misinformation. In fact, team members are already collaborating as part of the campus-wide Good Systems Initiative, a UT Bridging Barriers Grand Challenge to design the future of socially-responsible AI. Good Systems has become a major catalyst at UT in promoting projects on socially-responsible AI, and Micron Foundation support for this project will enable the research team to tackle the specific challenges of designing socially-responsible AI to combat misinformation.

“Our project will develop real use cases, interface designs, prototype applications, and user-centered evaluations,” said Lease. “By grounding AI research in the context of specific social problems, designers can directly consider and confront the societal context of use as AI models are conceived and refined.”The team members explain that this will aid the discovery of new insights into how good AI systems can be developed in general to maximize societal benefit.

The Micron Foundation sought proposals from multi-disciplinary research groups and non-profit organizations investigating how artificial intelligence, machine leaning, and deep learning can improve life while also addressing ethical issues, security, and privacy. Established in 1999 as a private, nonprofit organization with a gift from Micron Technology, the Micron Foundation’s grants, programs, and volunteers focus on promoting science and engineering education and addressing basic human needs.

Reading Metadata to Combat Disinformation and Fake News Campaigns

If you’ve ever reacted to a Facebook post, retweeted on Twitter, or commented on an Instagram story, then you’ve not only successfully used and engaged with these communication infrastructures, but you’ve also created your own digital trace of “metadata,” which Texas School of Information Assistant Professor Amelia Acker defines as “an index of human behavior.” 

Our activity on social platforms –such as favorites, likes, retweets, comments, and reactions are used mostly to advertise to us, but there is a dark side where manipulators, bots, and people in the business of disinformation and misinformation try to “appear human to the algorithms that police social networks,” says Acker, who is also a Research Affiliate at Data & Society Research Institute’s Media Manipulation Initiative

Acker dubs the manipulation of this information “data craft –a collection of practices that create, rely on, or even play with the proliferation of data on social media by engaging with new computational and algorithmic mechanisms of organization and classification.” 

In summer 2018, New Knowledge, a local data science firm in Austin, Texas, published findings about Russian-connected Twitter bots and fake Facebook accounts which were used to manipulate public discourse during the 2016 U.S. election. “Some of these hoaxes and fakes are rather crafty in their ability to circumvent the boundaries of platforms and their terms of service agreements” notes Acker. From election tampering to shifting political discourse around social debates like immigration reform and racial politics, Acker explains that the presence of false activity data has had a number of unpredictable consequences for social media users and society. 

Data craft is becoming more harmful because “more than half of Americans get their news primarily from social media,” says Acker. And this problem isn’t going away anytime soon. In fact, it’s about to get a lot worse as “bots are starting to mimic our social media activity to look more human” and ‘sockpuppets’ are becoming “more and more sophisticated to where they can now craft data to look like real user engagement with conversation online,” explains Acker.

By identifying and understanding disinformation tactics as data craftwork, information researchers can read social media metadata just as closely as algorithms do, and possibly with more precision than the platforms’ moderation tools.

With those in the business of data craft becoming smarter and craftier at faking what looks like authentic behavior on social media, what does this mean for us? Put simply, it will become more difficult for us to discern ‘real’ users and authentic account activities from fake, spammy, and malicious manipulations,” said Acker in a recent Data & Society report.

But there is a sense of hope, which according to Acker, lies in the metadata itself. “Metadata features such as account name, account image, number of likes, tags, and date of post can provide activity frequency signals that serve as clues for suspicious activity.” “Reading metadata surrounding sockpuppet accounts will often reveal intentions, slippages, and noise –which can further reveal automated manipulation,” claims Acker.  

“By identifying and understanding disinformation tactics as data craftwork, information researchers can read social media metadata just as closely as algorithms do, and possibly with more precision than the platforms’ moderation tools,” says Acker.Closely examining metadata such as the rapidity of account activity, follower/audience counts, post timestamps, media content, user bios, and location data, has led to thousands of fake accounts being detected by social media researchers and tech journalists. 

So while we may not be able to beat bots and manipulators at their data craft game, the future is hopeful when it comes to detecting and identifying disinformation. Understanding data craft and how it can manifest in the world of social media and metadata is the first step. The second is reading metadata that has been gamed, exploited, or changed. This, according to Acker, promises a new method for tracing the spread of misinformation and disinformation campaigns on social media platforms. It will also improve data literacy among citizens by providing a method to judge whether messages are authentic or deceptive.

Acker plans to use the case studies of “reading metadata” in her INF384M Theories and Applications of Metadata course in spring 2019 at the Texas iSchool. She hopes that her research will help educators, journalists, policy makers, technologists, and early-career professionals like students understand how bad actors can manipulate metadata to create disinformation campaigns. “The acquisition of this information and understanding is empowering and gives us an advantage in terms of deciphering which information is real and which is fake or manipulated.”
