In general, conflicts can and should be computed using Paper Matching Setup. However, there may be cases where you do not want to re-compute conflicts for all reviewers and papers; for example, if an author requested to add new coauthors after reviewers were already assigned to their paper. You can use the python client to manually check for conflicts between the reviewers and the new authors like so:

1. If you have not done so, you will need to install and instantiate the openreview-py client.

2. Get the note that you are interested in computing conflicts for. If you have a double blind venue, go to api.openreview.net/notes?id=<submission_forum> and get the id listed for "original". If you have a single blind venue, you can pass in the forum.

3. Get the profiles of the authors of the submission and the reviewers. The reviewer group id should be something like your conference id/Paper#/Reviewers, for example robot-learning.org/CoRL/2022/Conference/Paper99/Reviewers if the submission of interest is paper number 99.

4. Compute the conflicts. If no conflicts are found, an empty array will be printed. Otherwise, the array will contain the shared groups that put them in conflict with each other.

Bids, assignments, affinity scores, conflicts, etc. are saved as Edges in OpenReview.

Simply speaking, Edges are links between two OpenReview entities (Notes, Groups, Profiles, etc.).

If you are using automatic matching, you can generate conflicts automatically with Paper Matching Setup. Sometimes Program Chairs additionally want to create custom conflicts between certain users and certain papers. This can be done by posting an edge to the conflict edge invitation for your venue.

1. If you have not done so, you will need to .

2. Determine the conflict invitation you will be using. If you are creating a custom conflict edge for a reviewer, it would be <your_venue_id>/Reviewers/-/Conflict. If it is for an Area Chair, it would be <your_venue_id>/Area_Chairs/-/Conflict.

Assignments are stored as edges. You can view all of the assignment edges for a user in two ways:

View them at api.openreview.net

1. In your browser search bar, enter the following. If you want to view assignments for an Area Chair, change 'Reviewers' to 'Area_Chairs'. Replace your_venue_id with your full venue id. This will bring up all of the assignment edges for all of your venue's reviewers.

2. Now we want to filter by a particular reviewer. If you look at a specific edge, you will see that the field "tail" corresponds to the profile ID of the assigned reviewer. So to see only the assignments for reviewer ~User_One1, change your search query to the following:

Retrieve them with the Python Client

1. If you have not done so, you will need to .

2. Set a variable 'tail' to the profile ID of the user you are interested in, for example:

3. Set a variable 'invitation' to the invitation of the edges you are trying to view. If your user of interest is a reviewer, the invitation would be in the format <your_venue_id>/Reviewers/-/Assignment.

4. Retrieve all of the edges posted to that invitation for the user of interest.
