• In this project, we investigated the role of idioms in automated approaches to sentiment analysis.
  • To support idioms as features we collected a set of 580 idioms that are relevant to sentiment analysis.
  • To evaluate the results of sentiment analysis, we assembled a corpus of sentences in which idioms are used in context.
  • The results of sentiment analysis experiments are described in the papers cited below.


  • Idioms annotated with sentiment polarity.
  • Sentences that contain idioms, also annotated with sentiment polarity.
  • Local grammars that model idioms from the list above, which have been implemented in Mixup language. Matched idioms can be viewed using MinorThird (see screenshot). An example of how to run this Mixup file can be found here.
