Welcome to the homepage of Daniel Stein.

Currently I am a PhD student within the Human Language Technology and Translation Group
at the Chair of Computer Science 6 of the RWTH Aachen University.

The main research topics of the chair are

Pattern Recognition
Automatic Speech Recognition
Statistical Machine Translation
Image Processing

My personal research interests are hierarchical phrases for automatic translation, sign language, incorporation of sign language recognition features.

You can find me in room 6125a of our department, or contact me via mail or Xing/OpenBC.

Organisation

Assisting Student advisor for the following study programs offered by the Computer Science Department at RWTH Aachen University, since Summer 2008:
- Diploma Computer Science
- Bachelor Computer Science
Coordination of "nutritional" lunch talks on various tools, papers, translation issues, e.g. vi, LaTeX, R, octave, irregular on a weekly basis
Organisation of Powerpoint Karaoke at our institute, but even more irregular (roughly every three years)
Workshop on Sign Languages, Gebärdensprachworkshop GW2006, RWTH Aachen University, October 2006 with Jan Bungeroth.
Part of the Program Committee, 4th Workshop on the Representation and Processing of Sign Languages, LREC 2010, Malta.
