Abstract. In conjunction with the growth of on-line social media, an active line of work at the interface of computing and the social sciences has been exploring computational models for social phenomena that unfold in networks.In this talk, we consider some of the current models that are being developed in this area, with a focus on the question of how individuals evaluate one another in different settings. These models seek to capture arange of different effects in the process of evaluation, from the type of friend/enemy judgments that characterize the theory of structural balance in sociology to the ways in which credit is assigned to scientific researchers.
