Retrieve-then-Disambiguate: Scalable Reviewer Discovery

arXiv:2610.40768v1 Announce Type: new Abstract: The growing number of scientific submissions is straining the peer review process, while a large pool of relevant researchers remains unidentified and is therefore not considered as potential reviewers. We formulate the discovery of these researchers as a retrieval problem: given a submission, we retrieve and rank researchers based on domain similarity. We present retrieve-then-disambiguate, an open-source algorithm that identifies domain relevant researchers for a query submission by retrieving similar publications from the scientific literature and resolving ambiguous author names into unique researcher identities. We evaluate the algorithm on 500 astronomy and physics publications. We use ORCID-linked first authors, coauthors, and cited researchers as proxy labels to evaluate the recovery of researchers with known connections to each query publication. When retrieving the top 500 most similar papers, the algorithm recovers roughly 68\% of first authors, 60\% of coauthors, and 45\% of cited researchers.
