Zusammenfassung:
A central problem in networked information retrieval is database selection. Which databases have to be considered to meet the information need of a user? Originating from a decision theoretic model for database selection one finds out that estimating a number of relevant documents in a database is fundamental for database selection. Approaches to estimate this parameter are presented as well as an evaluation of these approaches. It is exposed that such an estimation with simple methods is not possible.
