Hi!

Dialogue

Welcome to my personal research website. I am currently working as a Postdoctoral Research Fellow in the Language Technology Group of the Department of Informatics, University of Oslo. My research is funded by a 3-years research grant from the Norwegian Research Council.

My general research interest is dialogue modelling and its applications to various language technology tasks. During my PhD, I developed a hybrid approach to dialogue management which combined expert domain knowledge and statistical models into a unified framework. One offspring of my work was the release of the OpenDial toolkit to build robust and adaptive spoken dialogue systems.

In my postdoctoral work, I am now focusing on the use of dialogue modelling for another application domain, namely machine translation. In spite of great progress in the recent years, machine translation remains poor at adapting translations to the relevant context. In order to translate a dialogue (say, film subtitles), current systems typically operate one utterance at a time and ignore the global coherence and structure of the conversation. The goal of this postdoctoral project is to enhance the contextual awareness of machine translation systems by incorporating features from the surrounding dialogue context and exploiting these features to dynamically modulate the translation outputs.

If you're interested in my research and would like to know more, feel free to drop me an email!





  News:

[22/10/2014] Raveesh Meena and I have written a feature article on spoken dialogue systems for XRDS, the flagship academic magazine for student members of ACM. You can access the full article here.
[22/10/2014] I am now back in Oslo after a 3-months research stay at the Idiap institute in Switzerland. Until december, I'll be lecturing on spoken dialogue systems as part of the INF5820 course on language technology applications.
[1/08/2014] I am delighted to visit the Idiap research institute in Switzerland for a period of 3 months (from August to October) in order to work together with Andrei Popescu-Belis on dialogue modelling for statistical machine translation.
