A Rank-Based Approach to Recommender System’s Top-K Queries with Uncertain Scores
Summary: Rank-based top-K queries for recommender systems with uncertain scores. Introduces RankDist to compute the probability of each item's rank under score distributions, enabling probabilistic ranking with guaranteed expected-optimality and empirical superiority over score-based baselines on standard benchmarks.
