Abstract

Sentiment analysis provides a useful overview of customer review contents. Many review websites allow a user to enter a summary in addition to a full review. It has been shown that jointly predicting the review summary and the sentiment rating benefits both tasks. However, these methods consider the integration of review and summary information in an implicit manner, which limits their performance to some extent. In this paper, we propose a hierarchically-refined attention network for better exploiting multi-interaction between a review and its summary for sentiment analysis. In particular, the representation of a review is layer-wise refined by attention over the summary representation. Empirical results show that our model can better make use of user-written summaries for review sentiment analysis, and is also more effective compared to existing methods when the user summary is replaced with summary generated by an automatic summarization system.
