Naver sentiment movie corpus v1.0

This is a movie review dataset in the Korean language. Reviews were scraped from Naver Movies.

The dataset construction is based on the method noted in Large movie review dataset from Maas et al., 2011.

Data description

  • Each file is consisted of three columns: id, document, label
    • id: The review id, provieded by Naver
    • document: The actual review
    • label: The sentiment class of the review. (0: negative, 1: positive)
    • Columns are delimited with tabs (i.e., .tsv format; but the file extension is .txt for easy access for novices)
  • 200K reviews in total
    • ratings.txt: All 200K reviews
    • ratings_test.txt: 50K reviews held out for testing
    • ratings_train.txt: 150K reviews for training


  • All reviews are shorter than 140 characters
  • Each sentiment class is sampled equally (i.e., random guess yields 50% accuracy)
    • 100K negative reviews (originally reviews of ratings 1-4)
    • 100K positive reviews (originally reviews of ratings 9-10)
    • Neutral reviews (originally reviews of ratings 5-8) are excluded
