document: Multi-objective ranking of comments on web With the explosion of information on any topic , the need for ranking is becoming very critical . Ranking typically depends on several aspects . Products , for example , have several aspects like price , recency , rating , etc. . Product ranking has to bring the `` best '' product which is recent and highly rated . Hence ranking has to satisfy multiple objectives . In this paper , we explore multi-objective ranking of comments using Hodge decomposition . While Hodge decomposition produces a globally consistent ranking , a globally inconsistent component is also present . We propose an active learning strategy for the reduction of this component . Finally , we develop techniques for online Hodge decomposition . We experimentally validate the ideas presented in this paper .
