As Research Director of the Arabic Language Technologies (ALT) group, Stephan is responsible for helping to define the overall research agenda of QCRI and of the ALT team in particular.
His own research focus is on machine translation, especially the so-called statistical machine translation (SMT), where statistical modeling and machine learning techniques are used to learn from existing (human) translations how to translate new sentences. In the team’s research they deal with fundamental questions like optimization in SMT, integrating morphology, novel reordering models, etc, but also how this can be turned into useful applications to support real-live multilingual communication and information access.
An additional interest, which Stephan hopes to explore more in the future, is to apply language technologies in educational applications. In particular, QCRI’s ALT team has started to develop CALL (computer assisted language learning) applications for Arabic.
Before joining QCRI Dr. Vogel was a research scientist at Carnegie Mellon University, Pittsburgh, where he advised 10 PhD and eight master's students, and visiting students from other universities. He also led or participated in a number of research projects, funded by NSF and DARPA, including TIDES and GALE.
