| Abstract: | Purpose/significance] This study identifies the features of false health information on social media and construct a list of false health information characteristics on social media, in order to provide certain theoretical support for the measurement of false health information features on social media, and also provide a useful reference for users and social media service platforms to distinguish false health information.Method/process] 1 004 pieces of empirical data from social media were collected, and the key features of false health information were extracted by programmatic coding. Then the chi-square test and analysis of variance were adopted to identify significant features of health misinformation. In addition, this study developed a list of features to identify health misinformation on social media.Result/conclusion] It was shown that the features of false health information on social media had three dimensions:surface features, semantic features, and source features. There were 11 main features and 29 sub-features. It was found that the features of "term packaging" on food safety topic was more notable than other topics; "exaggerated facts" on common diseases topic was more significant than other topics; the features of "lack of meta-information" and "fake authority" on healthcare topic were more prominent than other topics. |
