1. Denoising Neural Machine Translation Training with Trusted Data and Online Data Selection (2018 · 114 citations)
   Web-crawled and automatically mined parallel corpora often contain misaligned, partially translated or otherwise flawed sentence pairs, and NMT is more sensitive to such noise than SMT.
2. Dependency Tree-based Sentiment Classification using CRFs with Hidden Variables (2010 · 66 citations)
   The paper addresses sentence-level polarity classification (positive vs. negative) of subjective sentences in Japanese and English. Bag-of-words models handle this poorly because some words flip the polarity of the material they govern. For example, "prevents" turns a negative phrase about disease into a positive…
