LibRank: Neue Formen der Relevanzsortierung in bibliothekarischen Informationssystemen
In the LibRank project, a collaborative project with the ZBW Leibniz Information Centre for Economics, we investigated how new approaches to result ranking can be applied in library search systems. Here, we primarily focused on incorporating popularity factors like the number of citations and the number of downloads. Our large-scale evaluation of the different ranking approaches found that there is no single-best way to rank results in library search systems and that popularity factors do not improve the rankings considerably from a user point of view.
