LDA topic modeling for schizophrenia before and after renaming. Principle component analysis with 2-dimension was adopted to visualize the LDA topic modeling for the disease names before and after the revision. Number (Density) of circles indicate the degree of a significance of a specific media frame within a topic. Circles with a specific media frame can be redundantly and adjacently shown in the principle component dimensions, with a trend to aggregate with each other owing to similar news keywords or contexts. a LDA topic modeling for ‘Jungshinbunyeolbyung’ as mind split disorder before the revision of the schizophrenia name. b LDA topic modeling for ‘Jungshinbunyeolbyung’ as mind split disorder after the revision. c LDA topic modeling for ‘Johyeonbyung’ as attunement disorder after the revision. Abbreviations, C, Conflict frames; P, Policy frames; M, Medical frames; and N, neutral frames. For better visualization of the conflict frames (C), blue-colored close circles were used. The conflict frame with asterisk (*) in the Fig. 1c indicates the Gangnam homicide case committed by a schizophrenia patient in 2016
