Improving Document-Level Sentiment Analysis with User and Product Context

Understand

Past work that improves document-level sentiment analysis by encoding user and product information has been limited to considering only the text of the current review.

• We investigate incorporating additional review text available at the time of sentiment prediction that may prove meaningful for guiding prediction.
• Firstly, we incorporate all available historical review text belonging to the author of the review in question.
• Secondly, we investigate the inclusion of historical reviews associated with the current product (written by other users).
