Dr. Andreas Weiler

Post-doctoral Researcher

Areas of Interest

Andreas' research is situated in the area of processing and analyzing social media data streams. In particular, he studies how the magnitude of different event detection techniques that have been proposed for Twitter can be evaluated in terms of run-time and task-based performance. This work is the basis to develop adaptive and scalable event detection techniques in current work.

Background

Andreas studied Information Engineering at the University of Konstanz. In 2006, he received a Bachelor's Degree with a specialization in databases and information systems. He acquired a Master's Degree in Information Engineering with a focus on Computer Science in 2010. In his Master's Thesis Andreas designed and developed a client/server architecture for the open-source XML database BaseX. He joined the Database and Information Systems group as a PhD student in 2011. He received his Doctoral Degree for the dissertation entitled "Design and Evaluation of Event Detection Techniques for Social Media Data Streams in 2016.

Projects

Adaptive and Scalable Event Detection Techniques for Twitter Data Streams

In this project, we propose to address the need for adaptive and scalable event detection in Twitter in the tradition of Data Stream Management Systems (DSMS) research. [read more]

Blended Library (concluded)

The project is funded by the Ministry of Science, Research and Arts of Baden-Wuerttemberg. Concepts will be developed to support research cooperation, and learning processes within a physical "library of the future". This is done in close collaboration with the Library of the University of Konstanz, the work group Databases and Information Systems, the Knowledge Media Research Center Tuebingen and the university library of Tuebingen. [read more]
