Web Systems

Our group develops and operates several web systems. The following list briefly introduces them and points to the systems and additional resources.


BibSonomy is a social bookmarking system as well as the underlying technical platform (which also is the basis for PUMA). The system enables users to share and annotate bookmarks and publications. BibSonomy is used by scientists all over the world to find, store, manage, and cite scientific literature and to create and present publication lists.

  • BibSonomy is publicly available and free to use since 2006.
  • You can follow news on BibSonomy in our blog or on Twitter.
  • Developer information (source code, wiki, etc.) can be found at BitBucket .
  • For researchers, we offer datasets (anonymized, regular snapshots of data, containing posts with users, resources, and tags).
  • BibSonomy is run and developed in cooperation with the DMIR group of the University of Würzburg, and the L3S Research Center, Germany.


PUMA, the Academic PUblication MAnagement system, assists researchers, librarians, and students in their workflow with literature - for paper writing, course work, or literature lists to present on homepages or for reporting. PUMA is designed to be used in local installations at libraries, universities, or research institutions. PUMA connects functionality of publication servers, current research information systems, open access repositories, and content management systems.

  • PUMA uses the open source code of BibSonomy and is free to install and use at your institution.
  • PUMA is already in use in several German research institutions.
  • Try PUMA in our sandbox or learn more about PUMA and its integration!
  • We offer support for installation and maintenance, corporate identity, and development of individual features extending PUMA. Do not hesitate to get in touch with us.


Conferator is a social conference guidance system. It aims at supporting conference participants during all conference activities, i.e., enhancing conference planning, participation, and social interaction. Conferator employs active RFID tags (developed by the Sociopatterns consortium) for localizing conference participants and for observing their social contacts. Furthermore, the system provides profile information including links to different social networks.

  • Conferator has successfully been applied and demonstrated at different conferences and events, e.g., LWA 2010, LWA 2011, LWA 2012, ACM Hypertext 2011, and Informatik 2013.
  • Conferator is an open source and based on Ubicon platform, further information can be found here.
  • Contact us if you want to use Conferator during your event.

Nameling is the name search engine which assists you in finding a suitable given name. In order to reveal new interrelations between names, data mining and knowledge engineering techniques are applied to data from the social web and combined with the dynamics of actual name preferences of users in Nameling.

  • Nameling is publicly available and free to use since 2012.
  • You can follow news on EveryAware on our Twitter account @Nameling or on our Facebook page.
  • For researchers, we offer Datensätze of Nameling.


EveryAware provides rich methods for real-time analysis of objective sensor and subjective data, and gives its users a direct feedback about their measurements. We offer two smartphone applications to be used alongside EveryAware.

WideNoise Plus records the soundscape around you and displays your measurements on a world-wide map. You can attach tags and your personal perceptions to a recording, since not every lout sound is unpleasant.
