Domain adaptation

Sentiment analysis

Multi-Domain Sentiment Dataset

The Multi-Domain Sentiment Dataset is a common evaluation dataset for domain adaptation for sentiment analysis. It contains product reviews from from different product categories, which are treated as distinct domains. Reviews contain star ratings (1 to 5 stars) that are generally converted into binary labels. Models are typically evaluated on a target domain that is different from the source domain they were trained on, while only having access to unlabeled examples of the target domain (unsupervised domain adaptation). The evaluation metric is accuracy and scores are averaged across each domain.
