accuracies in the high 90%s. Unfortunately the performa
of these systems degrades drastically when they are applied

lation systems work fantastically for translating
ings but fall down when applied to
alternate domains. I''ll discuss re
search that aims to understand
what goes wrong when models are applied
outside their domain
and some (partial) solutions to this problem. I''

a range of different sources of error (some of which are
