. You have to answer the question based on the context.
Q: Intuitively, under-translated input words should contribute little to the NMT outputs, yielding much smaller word importance. By exploiting the word importance calculated by Attribution method, we can identify the under-translation errors automatically without the involvement of human interpreters.
Question: How do they measure which words are under-translated by NMT models?
A:
They measured the under-translated words with low word importance score as calculated by Attribution.
