Welcome to the homepage of Nicola Ueffing. I obtained my PhD from RWTH Aachen University, Germany, at the Chair of Computer Science VI. I joint the Interactive Language Technologies group at NRC Canada in April 2006.
My scientific interests include natural language processing, statistical machine translation, machine translation evaluation and machine learning. My focus is on confidence measures for statistical machine translation. In summer 2003, I was part of the team working on Confidence Estimation for Statistical MT at CLSP at Johns Hopkins University, Baltimore, MD.
Here is my list of publications.

I was also involved in some teaching and other activities at RWTH.
