Graph Representations and Applications of Citation Networks

Abstract

A citation network is a structure of linked documents that share a pool of authors and a pool of subjects, and via citations, provide references to related documents that have preceded them in the chronology of research. In this paper we review citation networks, and survey and categorize the operations that extract data from them. Our goal is to create a framework against which proposed implementations can be assessed, and to provide a basis for research in to algorithms and techniques that might be applied to citation networks. In particular, we seek to extend the concept of "search" over a citation network, to allow for ranked retrieval models in which a wide range of factors influence th..
