My work is currently focused on machine translation, but more broadly defined, my interest is to make use of the vast amount of information that is available in digital form.
My new book on neural machine translation is now available at amazon.com. My previous book on statistical machine translation is also still available at amazon.com.
More on the Machine Translation Group here. Come and join our weekly meeting!
I am also affilliated with the University of Edinburgh, some more information can be found on a web page there.
