Research

The research of our group currently focuses on certain areas of data mining and (multimedia) information retrieval. Furthermore, we are working on database integration (in particular, instance-based ontology integration).

For some research projects we cooperate with industry or public authorities. Recently, we started or had cooperations e.g. with Metro Group Information Technology, Media Invest/SJB FondsSkyline, and Landesamt für Natur, Umwelt und Verbraucherschutz Nordrhein-Westfalen.

We are always open to new cooperations regarding interesting problems within our research areas as well as concerning new exciting topics. Just contact us!

  Diese Arbeit entstand im Rahmen eines 2 semestrigen Masterprojekts. Die Grundlegende Idee war es Webseiten zu crawlen und Bilder und zugehörige Texte zu extrahieren. Aus den extrahierten Texten wurden Personennamen ermittelt und diese den erkannten Gesichtern auf den Bildern zugeordnet.
