We define LLM-mediated XAI as a process in which a large language model aggregates, prioritizes, and translates heterogeneous XAI outputs into a context-sensitive explanation tailored to the user’s decision situation. Semantic features, XAI modules and LLM-based summarization and synthesis enable the generation of explanations that are adapted in three ways: compressed for time-efficient decisions, translated into non-technical language, and progressively expandable for deeper inspection. Through a mixed-methods user study, including a quantitative study and a qualitative study, we analyze how users interpret, challenge and strategically rely on LLM-mediated explanations during real-world misinformation assessment tasks. The findings indicate that the approach reduces time-to-decision and supports critical inspection without inducing over-reliance. Progressive disclosure and different techniques to present information favored different user needs while conversational functionality was rarely used due to unclear benefits and fear of confusion.","lang":"eng"}],"date_created":"2026-05-05T16:16:34Z","title":"LLM-Mediated XAI Explanations: An AI Advisor for Fast and Calibrated Judgments on Potential Misinformation","author":[{"last_name":"Grimm","id":"74000","first_name":"Valentin","full_name":"Grimm, Valentin"},{"orcid":"0000-0003-0937-3551","id":"45672","first_name":"Jessica","last_name":"Rubart","full_name":"Rubart, Jessica"},{"full_name":"Herder, Eelco","last_name":"Herder","first_name":"Eelco"},{"full_name":"Röcker, Carsten","last_name":"Röcker","id":"61525","first_name":"Carsten"}],"editor":[{"full_name":"Balke, Wolf-Tilo","last_name":"Balke","first_name":"Wolf-Tilo"},{"last_name":"Plötzky","first_name":"Florian","full_name":"Plötzky, Florian"},{"first_name":"Marc","last_name":"Spaniol","full_name":"Spaniol, Marc"},{"first_name":"Eelco","last_name":"Herder","full_name":"Herder, Eelco"},{"full_name":"Manikonda, Lydia","last_name":"Manikonda","first_name":"Lydia"},{"first_name":"Haiming","last_name":"Liu","full_name":"Liu, Haiming"},{"first_name":"Luis-Daniel","last_name":"Ibáñez","full_name":"Ibáñez, Luis-Daniel"},{"full_name":"Rezapour, Rezvaneh","first_name":"Rezvaneh","last_name":"Rezapour"}],"year":"2026","publication":"WebSci Companion '26: Companion Publication of the 2026 18th ACM Web Science Conference","language":[{"iso":"eng"}],"department":[{"_id":"DEP5023"}]}]
