Teaching

Note:  German universities have two terms per year:  a winter semester (WiSe – Wintersemester) and a summer semester (SoSe – Sommersemester).

Projects

Current projects:

  • KONECT – Koblenz Network Collection
  • Social Sensor – Sensing User-generated Input for Improved Media Discovery and Experience (EU FP7)
  • KoMePol – Forschungsschwerpunkt "Kommunikation, Medien und Politik" (Communication, media, and politics)

Former projects:

  • WeKnowItEmerging, Collective Intelligence for Personal, Organisational and Social Use (EU FP7)
  • ROBUST – Risk and Opportunity Management of Huge-scale Business Community Cooperation (EU FP7)
  • MULTIPLA – Crossing the Boundaries of Domains and Languages (DFG)

Interests

When I passed my PhD in Koblenz, my colleagues gave my a t-shirt that summarizes my research interests.  On it was written "Everything is a Network". My research interests indeed follow these lines:

 Other interests of me include:

  • Web Science
    • Beside being part of the Institute for Web Science and Technologies at the University of Koblenz–Landau, I have been involved with the organization of the Web Science Conference and related Web Science workshops, and am also involved on multiple projects in which aspects of social sciences play a role.  I have also been present on the Web Science conference roster since 2011.
  • Interestingness on Twitter
    • Since 2010, I have written multiple papers about the notion of interestingness as applied to postings on Twitter.
  • Tensor decomposition and joint diagonalization
    • In addition to matrix decomposition methods for graphs, I have written papers on the use of tensor factorization and related methods to analyse graphs.

PhD Thesis

I wrote my PhD thesis On the Spectral Evolution of Large Networks under supervision of Prof. Dr. Steffen Staab, Prof. Dr. Klaus Obermayer and Prof. Dr. Christian Bauckhage in 2011.

Download:   "On the Spectral Evolution of Large Networks"  (print version)

In my PhD thesis, I studied the spectral characteristics of large dynamic networks and formulate the spectral evolution model.  The spectral evolution model applies to networks that evolve over time, and describes their spectral decompositions such as the eigenvalue and singular value decomposition.  My main result is an interpretation of the spectrum and eigenvectors of networks in terms of global and local effects. I show empirically that the spectrum describes a network on the global level, whereas eigenvectors describe a network at the local level, and derive from this several new link prediction methods.
