IBM Debater® Sentiment Lexicon of IDiomatic Expressions (SLIDE)


SLIDE (Sentiment Lexicon of IDiomatic Expressions) is a resource for sentiment analysis, created via crowdsourcing. The lexicon includes 5,000 frequently occurring idioms, as estimated from a large English corpus. The idioms were selected from Wiktionary, and over 40% of them were labeled as sentiment-bearing. Each idiom was annotated as positive, negative, neutral or inappropriate by at least ten annotators. The lexicon includes a sentiment label along with the distribution of sentiment annotations. Our labels are assigned by taking the label with the greatest number of votes from the crowdsourced annotation. In the case of ties between positive (or negative) and neutral, the label is positive (resp. negative). In the rare cases of ties between positive and negative, we use the neutral label. The resulting lexicon has 946 positive idioms, 1,108 negative, 2,945 neutral, and 1 inappropriate.

The released data file has 12 columns:

  • Column A: Idiom expression
  • Column B: Link to idiom in Wiktionary
  • Column C: Count of positive annotation
  • Column D: Count of negative annotation
  • Column E: Count of neutral annotation
  • Column F: Count of annotation where the expression was deemed vulgar or inappropriate
  • Column G: Total annotations
  • Column H: Percent positive
  • Column I: Percent negative
  • Column J: Percent neutral
  • Column K: Sentiment label
  • Column L: Ambiguous expression filter — ‘X’ indicates removal (see paper, Section 4)
