Welcome to the Database Research Group
The Database Research Group is part of the Department of Computer Sciences
at the University of Salzburg, Austria. Our research interests include
data-centric applications in database and information systems with a
particular focus on similarity search queries over large data collections,
for example, approximate matching of strings and trees, efficient indexes
for distance computations, and top-k queries. Other fields of research
include load balancing algorithms for distributed frameworks like MapReduce
and queries in geographic information systems. The research results are new
algorithms with performance guarantees, which are implemented and evaluated
on the motivating application.
