Summary
This paper investigates the overtime evolution of citation and author networks and discusses the two processes that mainly govern the growth/evolution of such networks: aging and growth. The authors propose a model that can fit the systematic deviations from power distribution of citation networks well while accounting for the inter-related nature of the paper citation and co-authorship networks and importance of topic distributions. The model aims for integrating the following properties of citation networks:
- Authors have a bias to cite recent papers. Even highly cited papers stop receiving citation after a certain amount of time passed. This feature works against the richer get richer phenomenon enforced by aging, and frequently prevents a scale-free distribution of connectivity.
- Authors have a tendency to cite papers from the reference list of papers they have read, which is a recursive follow up of links in the network.
Brief description of the method
The model proposed in this paper is called TARL which encompasses Topics, Aging, and Recursive Linking. The model attempts to capture different roles of the authors in (i) producing, (ii) storing, and (iii) disseminating information directly by (co)authorship or indirectly by reading/citing others’ papers.
