This dataset is distributed for Aspect Based Sentiment Analysis (ABSA), Task 4 of SemEval-2014. It consists of 3044 English sentences from the restaurant reviews of Ganu et al. (2009). The original dataset of Ganu et al. included annotations for coarse aspect categories and overall sentence polarities; we modified the dataset to include annotations for aspect terms occurring in the sentences, aspect term polarities, and aspect category-specific polarities. We also corrected some errors (e.g., sentence splitting errors) of the original dataset. Experienced human annotators identified the aspect terms of the sentences and their polarities.
