Finding Diverse, High-Value Representatives on a Surface of Answers
Summary: Proposes k-DHR to extract a diverse, high-value subset from a surface of answers, where elevation encodes quality over answer attributes. Establishes submodular, monotone objective; provides efficient algorithms with guarantees; demonstrates gains on lead-finding and fact-checking tasks, and practical applications.
