Finding my office at the Institute for NLP (IMS)


  • I have moved to the Center for Information and Language Processing at the University of Munich (LMU München). This web page will no longer be updated - please see my new web page here

  • The second phase of the Morphosyntax for SMT project has been approved by the DFG!

  • I will give a keynote talk at TALN 2013 on translating to morphologically richer languages

  • Our Dagstuhl Seminar on Statistical Techniques for Translating to Morphologically Rich Languages has been accepted, which is great news for the Morphosyntax for SMT project. The organizers are Alexander Fraser, Kevin Knight, Philipp Koehn, Helmut Schmid, and Hans Uszkoreit. The seminar will take place in February 2014. 60 top researchers will be invited to have free-ranging discussions of how to move forward on this important problem. (For more information on Dagstuhl Seminars, click here)

  • I will serve as a tutorials chair at ACL 2014 in Baltimore, looking forward to your applications.

  • Congratulations to Hassan Sajjad for passing his defense! His topic: Statistical Models for Unsupervised, Semi-supervised and Supervised Transliteration Mining. He has also accepted a position with Stephan Vogel and Preslav Nakov at the Qatar Computing Research Institute.

  • I was an organizer of the Johns Hopkins Summer Workshop on Domain Adaptation for Machine Translation. This involved 6 weeks of intensive work on taking advantage of out-of-domain data in translation, conducted by 13 researchers on location at the Center for Language and Speech Processing at the Johns Hopkins University in Baltimore.

  • Paper accepted to Computational Linguistics Journal: Knowledge Sources for Constituent Parsing of German, a Morphologically Rich and Less-Configurational Language, by Alexander Fraser, Helmut Schmid, Richard Farkas, Renjing Wang, Hinrich Schuetze (abstract   preprint)

  • I taught Statistical Machine Translation at the Summer School in Advanced Language Engineering at Kathmandu University in Nepal in September 2012. This was supported by a DAAD grant. We had participants from Nepal, Pakistan and Sri Lanka (participants from Bangladesh and Bhutan were also invited, but were unable to attend).
