An online review system determines scores for document authors and document reviewers. An author score is based on a number of comments added to a document by reviewers. One way to compute the author score is to use a ratio of a number of comments provided by reviewers of a document to a number of lines of document contents provided by the author. A reviewer score for a reviewer is based on an amount of comments subsequently made by other reviewers, and on the document content itself, such as a ratio of a number of comments provided in subsequent reviews of a document to a number of lines of original document contents. In some embodiments, the online review system monitors trends in scores of individuals or teams.
