Research Interests
I was a research assistant in the
Computer Science Department,
chair Intelligent Information and
Communication Systems (IICS),
at the University of Hagen.
My work was centered around the development of natural language
interfaces to databases, geographic information retrieval,
and semantic information retrieval.
The title of my dissertation is
"Formale Interpretation von Nutzeranfragen für natürlichsprachliche
Interfaces zu Informationsangeboten im Internet"
(Formal interpretation of user queries for natural language interfaces
targetting information services on the internet).
