Guidelines discussion: another interaction with research
Topic model of CBCT media discussion source Hicks’ brain
Topic model of research literature source Hicks’ classifying abstracts
Topic overlaps Research literature
Professional media
Conclusions
• Professional media are symbiotic with the scholarly literature
• A lot of media posts draw on journal articles
• Topics are similar, with professional media emphasizing contextualization and journal articles emphasizing technical precision
• Future work – hierarchical topic model across heterogeneous literature and discourses to develop metrics of this interaction
