Stigma Attitudes Toward HIV/AIDS From 2011 Through 2023 in Japan: Retrospective Study in Japan

The stigma model had a slightly lower performance due to the lack of training data for the mark category (less than 1% incidence rate), though it was within the acceptable range. In the antistigma model, the mark category was excluded due to its extremely low incident rate. The additional model constructed to classify tweets that were considered neither stigma nor antistigma into general education, irrelevant, or neutral categories had an AUC of 0.92.
