Research Interests
My research interests were in the beginning as research
assistent in the area of automtatic classification of
documents. Within the DFG projekt DAFFODIL this moved to the areas:
- user-oriented Digital Libraries and evaluation
- distributed information retrieval
- service-oriented architectures
- data integration
- user-oriented interactive information seeking and searching
- personalisation, recommendation and adaptivity
- context oriented information retrieval
- longterm preservation
During my dissertation and ask task leader in DELOS Network of
Excellence I started to research in the evaluation of digital libraries.
The dissertation is finished and can be found here
.
My complete CV can be found here: CV.
Since August, 1st 2007 i am employed at the distance university
Hagen, chair of Multimedia and Internet Applications.
Current my research focuses on the modelling of preservation systems
within our project SHAMAN where I concentrate on indexing and searching for
archived objects.
