Shapley Revisited: Tractable Responsibility Measures for Query Answers
Summary: Revisits Shapley-based responsibility for query answers and proposes WSMS as a tractable alternative. WSMS equates to Shapley values of a tailored game and yields tractable data complexity for many queries, including UCQs. (summarized by gpt-5-nano on Feb 09 2026)
