This just in(novation): NSF grant is good news for researchers studying journalism, recommender systems

By Joe Arney

Robin Burke is very familiar with the original news recommender system.听

Before he was a respected expert in the recommender systems that are key to digital life鈥攅verything from suggesting the next song in a playlist, to suggesting an online dating partner鈥擝urke wore many hats at the community newspaper his father ran in California. Doing odd jobs as a photographer, darkroom technician, reporter and proofreader, Burke got to see how editors would shape each edition and choose which stories got the most play.

鈥淣ow, all that context, and that control over priorities, has shifted to these platforms, whether it鈥檚 your social media feed or an app like Google News,鈥 said Burke, professor and chair of the Information Science department. 鈥淭hat journalistic voice isn鈥檛 there anymore.鈥澨

Burke is part of a team of researchers from a group of top schools, including Minnesota, Northwestern and Clemson, that is seeking to better understand how digital recommender systems are performing the tasks once left to professional editors. The team secured a $2 million grant from the National Science Foundation to build a platform for researchers eager to experiment with the artificial intelligence that powers news recommender systems.听

鈥淲e have put all this control over the public square of journalistic discourse into the hands of companies that don鈥檛 have any transparency or accountability relative to what they鈥檙e doing. I think that鈥檚 dangerous.鈥欌

It could be game-changing technical infrastructure for academic researchers, who are locked out of the proprietary systems built and studied by tech and social media companies.听

鈥淭he people who do this kind of research in industry don鈥檛 publish very much about it, so we don't know exactly what's going on in terms of how their systems work, or how well they work,鈥 Burke said. 鈥淪o the people at Google News, for instance, can do these experiments, but people like me can鈥檛.鈥

Hot off the digital presses

It's an urgent consideration because the way we get our news is changing鈥攁 2022 Pew Research Center survey found one in 10 U.S. adults get their news on TikTok; for American adults under 30, it鈥檚 more like one in four.

鈥淲e have put all this control over the public square of journalistic discourse into the hands of companies that don鈥檛 have any transparency or accountability relative to what they鈥檙e doing,鈥 he said. 鈥淚 think that鈥檚 dangerous. And so, it鈥檚 important to think about what the alternatives might look like.鈥

Those alternatives are bigger than just how news is recommended. The business model governing recommendations is optimized to sell ads while keeping users on a platform. As part of his work, Burke hopes researchers can experiment with alternative incentives that reimagine how we engage with technology.听

That ties back to Burke鈥檚 main research thread, which concerns bias in recommender systems. His work aims to create 鈥渇airness-aware鈥 algorithms that eliminate inequality around, for instance, gender and ethnicity鈥攚hich is closely related to what he鈥檚 building through NSF.

鈥淚f a system only shows us the news stories of one group of people, we begin to think that is the whole universe of news we need to pay attention to,鈥 he said.

Some of the early deliverables of the project may include a newsletter鈥攄elivered through a major national news outlet鈥攖hat would deliver recommendations to readers through a daily news update, and eventually a mobile news app that will help researchers understand the effectiveness of recommender systems in this space.听

If those projects are successful, Burke鈥檚 team will apply for additional NSF funding to further build out a robust system that will eventually become self-funded through contributions from other researchers.听

鈥淭o do this right, you need scientific infrastructure鈥攖he same way they build space telescopes and supercolliders,鈥 Burke said. 鈥淭his grant is about creating a piece of research infrastructure where somebody can come to the project and say, 鈥楬ere鈥檚 my experiment, here鈥檚 my code, I want to deliver recommendations to a thousand users over six months and see what happens.鈥欌
