The Frontiers Review Forum has the tools to easily find relevant reviewers for a submission.
Editors can review the keyterms entered at submission, as well as add new keyterms, and use these to generate a new list of Reviewers Suggestions.
From the Review Forum, select the Manage Reviewers tab, and then Suggested Reviewers > KeyTerms.
From here Editors can use the slider tool to increase/decrease Keyterm relevancy, as well as define their own list of keyterms, to generate a shortlist of reviewer recommendations. These are based based on matching the keyterms with the potential reviewers publications.
Once you have edited the Keyterms and their importance, select Apply. The Suggested Reviewers list will then be updated to match your criteria.
