A new research paper introduces WARP, a post-retrieval algorithm designed to improve the accuracy of opinion summarization from large document collections. Unlike existing methods that may overlook minority viewpoints or fail to capture sentiment intensity, WARP calibrates retrieved documents to better match the population's opinion distribution. The algorithm utilizes Wasserstein-1 distance to ensure that the sentiment-intensity distribution of selected documents aligns with the target population, addressing limitations of KL and JS divergence methods. Tested across three review domains, WARP demonstrated significant reductions in distributional error with low latency, leading to preferred generated answers by an LLM panel. AI
