A total of 6,822 local news articles published from 2018 through \n2022, and 190 scientific abstracts published from 2018 through 2023 were compiled \nfor use in a Structural Topic Model (STM), a statistical text-mining approach that \nidentified latent themes within a collection of documents while incorporating \ndocument-level metadata to explain topic prevalence. The model inputs included \nthe text of each news article and scientific abstract along with associated \nmetadata (e.g., author, title, date, publisher, location of the news publisher; \ncitation information for scientific abstracts). Due to proprietary restrictions, \nthe full text of the local news articles (NewsArticles.xlsx) is not included in \nthis data release. Instead, we provide the scientific abstracts input file \n(SCOPUS_scientificAbstracts.csv), the R scripts used to generate the STM analysis \nfor both the news articles (STM_newsArticles.R) and scientific abstracts \n(STM_scientificAbstracts.R), and the corresponding model output showing the main \ntopics (STM_newsArticles_output.png and STM_scientificAbstracts_output.png). \nThis data release supports the analyses presented in the corresponding journal \narticle (https://www.doi.org/TBD).
