USFD’s Phrase-level Quality Estimation Systems
Varvara Logacheva, Frédéric Blain, Lucia Specia · 2016
We describe the submissions of the University of Sheffield (USFD) for the phraselevel Quality Estimation (QE) shared task of WMT16.We test two different approaches for phrase-level QE: (i) we enrich the provided set of baseline features with information about the context of the phrases, and (ii) we exploit predictions at other granularity levels (word and sentence).These approaches perform closely in terms of multiplication of F 1 -scores (primary evaluation metric), but are considerably different in terms of the F 1scores for individual classes.
