Abstract

The problem to assign papers to referees gained a considerable interest in the recent years, especially in the scope of conference management systems. These systems need to achieve a fair and balanced distribution of papers among referees, where the conditions of fairness and balance may be defined in several ways. We present two algorithms to distribute a possibly large number of papers among a smaller number of referees, each paper requiring k reports. The first one is an approximation algorithm, using an iteration of weighted maximum matching in bipartite graphs. The second one is an exact algorithm based on b-matching. The optimality criterion for the assignment is not based on a local view of each referee, but on a global performance of the whole k-assignment satisfying a fairness criterion. We introduce an objective function for the k-assignment problem ensuring a specific notion of fairness when it is maximized. We show how a few precisely defined fairness criteria can be achieved that way. This includes a particularly notable extension of rank-maximality, a notion introduced by Irving et al. Our second algorithm computes in polynomial time optimal k-assignments with respect to the aforementioned fairness function.
