document: Modeling the author bias between two on-line computer science citation databases We examine the difference and similarities between two on-line computer science citation databases DBLP and CiteSeer . The database entries in DBLP are inserted manually while the CiteSeer entries are obtained autonomously . We show that the CiteSeer database contains considerably fewer single author papers . This bias can be modeled by an exponential process with intuitive explanation . The model permits us to predict that the DBLP database covers approximately 30 % of the entire literature of Computer Science .
