| Abstract: | This paper continues the attempt of Part I to develop a coherent family of measures of influence between classes of documents, for example, language or nationality classes, as indicated by citation choice. In this paper we focus on situations in which there is some ambiguity as to how to assign items to a class. For simplicity, we change our focus from citations to co-authorship patterns, restricting most of our discussion to papers with two authors. Like the earlier paper, we propose very simple models of the citation decision, and base our measures on the parameters that appear in the model. |
