This Open Access Week event centers on the ethics of reuse of community-based labor, including for AI projects and products. Madiha Zahrah Choksi (Columbia University Libraries) takes a historical approach, and contextualizes LLMs as tools produced through community-based labor, and compares mainstream AI technologies to historical tools that have long performed similar functions. Zachary McDowell (University of Illinois at Chicago) and Matthew Vetter (Indiana University of Pennsylvania) explore the "re-alienation of the commons" and the labor dynamics within Wikimedia projects, including ethical implications and historical context of community-driven knowledge production.
