Hi everyone, The July 2025 Research Showcase will be live-streamed tomorrow(!), Wednesday, July 16, at 9:30 AM PT / 16:30 UTC. Find your local time here <https://zonestamp.toolforge.org/1750264200>. Our theme this month is *The Impact of LLMs on Knowledge Production Communities*.
*We invite you to watch via the YouTube stream: https://www.youtube.com/live/R9zsL07v8YI <https://www.youtube.com/live/R9zsL07v8YI>.* As always, you can join the conversation in the YouTube chat as soon as the showcase goes live. Our presentations this month: *The Rise of AI-Generated Content in Wikipedia* By *Creston Brooks and Denis Peskoff (Northwestern University)*In the age of online AI inundation, how frequently are people using LLMs when creating new Wikipedia articles and for what purposes? In the summer of 2024, we took initial steps towards addressing these questions by using two AI-generated text detectors, GPT-Zero and Binoculars, to compare detection scores from Wikipedia articles written in August 2024 to those created before the release of GPT-3.5 in March 2022. After calibrating each tool, we conduct a small case study, inspecting each of the 45 English articles flagged as AI-generated by both tools to better understand the motivations for using LLMs to create Wikipedia pages. *The consequences of generative AI for online knowledge communities*By *Gordon Burtch (Boston University's, Questrom School of Business)* Generative artificial intelligence technologies, especially large language models (LLMs) like ChatGPT, are revolutionizing information acquisition and content production across a variety of domains. These technologies have a significant potential to impact participation and content production in online knowledge communities. We provide initial evidence of this, analyzing data from Stack Overflow and Reddit developer communities between October 2021 and March 2023, documenting ChatGPT’s influence on user activity in the former. We observe significant declines in both website visits and question volumes at Stack Overflow, particularly around topics where ChatGPT excels. By contrast, activity in Reddit communities shows no evidence of decline, suggesting that social fabric plays a crucial role as a buffer against the community-degrading effects of LLMs. Finally, the decline in participation on Stack Overflow is found to be concentrated among newer users, indicating that more junior, less socially embedded users are particularly likely to exit.
