New metric RDQ evaluates multi-answer retrieval systems

Researchers have introduced a new evaluation metric called Rank-Deviation Quality (RDQ) designed for retrieval and ranking systems. RDQ is adaptable to queries with varying numbers of correct answers, from a single result to multiple valid options. It scores candidate rankings by considering the position of retrieved reference items and a penalty for rank deviation, with parameters to control tolerance for misordering. RDQ operates on ordinal rankings, making it suitable for annotators using pairwise or listwise judgments, and it accounts for both the items returned and their order. AI

IMPACT This new metric could improve the evaluation of AI-powered search and recommendation systems by better handling queries with multiple valid results.

    Rank-Deviation Quality: A Distance-Aware Metric for Multi-Answer Retrieval and Ranking Evaluation

    We introduce Rank-Deviation Quality (RDQ), an evaluation metric for retrieval and ranking systems that adapts to queries with varying numbers of reference items, from a single correct answer to many valid results. RDQ scores a candidate ranking against an ordered reference list (…
