What it Does
The Bid Stage is a feature of the OpenReview Paper Matching system that allows reviewers to indicate their preference of which papers they would like to review and place bids. See Score Specification to see how bids are then converted into scores.
When to Use it
The Bid Stage should not be run until after the submission deadline, except in the case of public, single blind venues. For public and single-blind venues, the Bid Stage can be run before the submission deadline if they first run 'Post Submission Stage' to create paper groups.
It is recommended that venues first run Paper Matching to compute conflict of interest before opening the Bid Stage, but this is not required. If the conflict of interest scores are taken into account, the reviewers' own papers will be excluded from their bid selections.
