Searching for Fairness

⮴ Talks

This is the resource page for my keynote talk at the AI & Society Conference on June 28 in Zhuhai, China, entitled “Searching for Fairness: Grounding and Measuring Fairness and Social Impacts in Information Access”.

Abstract

Information access systems, such as search engines, recommender systems, and conversational agents, are used daily by billions of Internet users and have a profound impact on users’ information experiences, access to knowledge, and understanding of the world and people around them. These systems differ in crucial ways from the kinds of systems most frequently studied in the algorithmic fairness literature, requiring new techniques to properly understand and measure their social impacts. In this talk, I will discuss what makes these systems different and interesting; ground the quest for fairness and mitigating social harms in the varying goals of recommender systems; and describe several specific approaches and a general philosophy for measuring and mitigating harms in information access and other AI systems.
