Abstract
While ancient scientists often had patrons to fund their work, peer review of proposals for the allocation of resources is a foundation of modern science. A very common method is that proposals are evaluated by a small panel of experts (due to logistics and funding limitations) nominated by the grant-giving institutions. The expert panel process introduces several issues, most notably the following: (1) biases may be introduced in the selection of the panel and (2) experts have to read a very large number of proposals. Distributed peer review promises to alleviate several of the described problems by distributing the task of reviewing among the proposers. Each proposer is given a limited number of proposals to review and rank. We present the result of an experiment running a machine-learning-enhanced distributed peer-review process for allocation of telescope time at the European Southern Observatory. In this work, we show that the distributed peer review is statistically the same as a ‘traditional’ panel, that our machine-learning algorithm can predict expertise of reviewers with a high success rate, and that seniority and reviewer expertise have an influence on review quality. The general experience has been overwhelmingly praised by the participating community (using an anonymous feedback mechanism).
