Does the Future Need
Translators?

TAUS Industry Leaders Forum 2016
Very competitive research area
Steady performance improvements
Recent paradigm shift: from SMT to NMT
Strong adoption by translation industry
Strong adoption by global players
This naturally creates great expectations … and worries!
Progress in Machine Translation

MT is a very very hard problem
and still only partially explored
Difficulty of tasks is unpredictable
we don’t know how far we are from the solution
Neural MT has improved performance
on a few languages only (so far)
State-of-the-art still bad when translating
into morphologically rich languages
between distant language pairs
Still not enough language resources available
But

Translators will leverage MT more and more
get rid of routine and boring translations
MT will learn from translators
error repairs, style, terminology, …
Post-editing effort (PE) for technical translation:
< 5% PE for popular pairs EN->FR,ES,PT,IT,AR,…
< 10% PE for harder pairs EN -> RU,DE,FN,TR,ZH,JP
< 15% PE for well resources non-English
E.g. UN and EU language pairs
My optimistic 5-year predictions
