Theseus/ImageCLEF workshop on visual information retrieval evaluation


The THESEUS/ImageCLEF Workshop on Visual Information Retrieval Evaluation was held in Corfu, Greece on September 29, 2009 and invited contributions from the following fields:

  • Evaluation of Visual Information Retrieval and Annotation Methods
  • Image Retrieval / Image Annotation with Application on Photos, Medical data and Robotic vision
  • Multi-label Image Annotation supported by Knowledge Structures (Ontologies)

The workshop was open to everyone interested in one of the fields. Registration was free.

The workshop was co-located with the CLEF 2009 Workshop(

Date: September 29, 2009
Organizers: Peter Dunker, Henning Müller, Stefanie Nowak, Judith Liebetrau
Location: University of Corfu, Greece, Department of Informatics, Plateia Tsirigoti 7, Aretaios Building, Room 3, Second Floor (see numbers 7,8).


The THESEUS/ImageCLEF workshop follows the tradition of preceeding QUAERO and MUSCLE Workshops between 2005 and 2008. The aim of this workshop is similar to the aim of its predecessors in giving better perspective to participants of ImageCLEF and allow for discussion of topics related to visual information retrieval. Additionally, a special focus is set on information retrieval supported by structured knowledge, e.g. by using ontologies.

The Workshop Program is now available. Additionally, a Proceedings Preview with all paper titles and all authors is now available. The proceedings are published with ISBN and can be accessed at the Fraunhofer Verlag (the full text .pdf is available here). The proceedings were handed out to the participants of the workshop in digital and printed form.

Keynote Speaker

Stefan Rüger, Knowledge Media Institute, The Open University
Title: "More than a thousand words"
This talk examines the challenges and opportunities of Multimedia Search, i.e., finding multimedia by fragments, examples and excerpts. What is the state-of-the-art in finding known items in a huge database of images? Can your mobile phone take a picture of a statue and tell you about its artist and significance? What is the importance of geography as local context of queries? To which extent can automated image annotation from pixels help the retrieval process? Does external knowledge in terms of ontologies or other resources help the process along?

Ralf Schäfer, Department Image Processing, Fraunhofer HHI
Title: "Theseus Project - Semantic and Image Processing Technologies and its Applications"
