Our goal: trace the movement of knowledge through heterogeneous literatures

Discussion of research findings in media

• ~1750 or approximately 6% of articles on 24 blogs, Dr Bicuspid & DentalTown discuss findings of research articles • articles containing “journal of”, compendium or “abstract “

• ~ 2.7x other media mentions

• Sources vary: • 25% or 765 posts on Jablow blog are abstracts of research articles • 11% or 572 articles on Dr Bicuspid discuss research articles • 41% or 198 posts on Dental Dude blog discuss research articles

• No lag • media discusses articles the same month they are published or become available

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
