Comment: Citation Statistics (2009)
Lehmann, Sune, Lautrup, Benny E., Jackson, Andrew D.
We discuss the paper "Citation Statistics" by the Joint Committee on Quantitative Assessment of Research [arXiv:0910.3529]. In particular, we focus on a necessary feature of "good" measures for...
Link communities reveal multi-scale complexity in networks (2009)
Ahn, Yong-Yeol, Bagrow, James P., Lehmann, Sune
Networks have become a key approach to understanding systems of interacting objects, unifying the study of diverse phenomena including biological organisms and human society. One crucial step when...
The art of community detection (2008)
Gulbahce, Natali, Lehmann, Sune
Networks in nature possess a remarkable amount of structure. Via a series of data-driven discoveries, the cutting edge of network science has recently progressed from positing that the random graphs...
The Network of Subject Co-Popularity in Classical Archaeology (2008)
Schich, Maximilian, Hidalgo, César, Lehmann, Sune, Park, Juyong
Im vorliegenden Aufsatz kartieren wir komplexe Netzwerkeigenschaften der Archäologischen Bibliographie. Insbesondere beleuchten wir die allgemeine Struktur thematischer Unterteilungen sowie...
Lehmann, Sune, Schwartz, Martin, Hansen, Lars Kai
We present a novel method for detecting communities in bipartite networks. Based on an extension of the $k$-clique community detection algorithm, we demonstrate how modular structure in bipartite...
Deterministic Modularity Optimization (2007)
Lehmann, Sune, Hansen, Lars Kai
We study community structure of networks. We have developed a scheme for maximizing the modularity Q based on mean field methods. Further, we have defined a simple family of random networks with...
Measures and Mismeasures of Scientific Quality (2005)
Lehmann, Sune, Jackson, Andrew D., Lautrup, Benny E.
We present a general Bayesian method for quantifying the statistical reliability of one-dimensional measures of scientific quality based on citation data. Two quality measures used in practice --...
