作者：

Highlights：

• Sentiment analysis can be used to determine the general tone of a consumer review.

• We compare the output of several SA tools to each other and to star ratings.

• Results show that SA can substitute for, and often outperforms, star ratings.

• Contextual factors, such as product type, moderate SA accuracy.
