    Mixed Feelings: Cross-Domain Sentiment Classification of Patient Feedback
    (University of Tartu Library, 2025-03) Rønningstad, Egil; Storset, Lilja Charlotte; Mæhlum, Petter; Øvrelid, Lilja; Velldal, Erik; Johansson, Richard; Stymne, Sara
    Sentiment analysis of patient feedback from the public health domain can aid decision makers in evaluating the provided services. The current paper focuses on free-text comments in patient surveys about general practitioners and psychiatric healthcare, annotated with four sentence-level polarity classes - positive, negative, mixed and neutral - while also attempting to alleviate data scarcity by leveraging general-domain sources in the form of reviews. For several different architectures, we compare in-domain and out-of-domain effects, as well as the effects of training joint multi-domain models.
