Tracking the spread of ideas in academia with text analysis
Claire Maiers and Nicholas Napoli aimed to uncover the patterned ways by which ideas move through social systems. They examined the ways in which concepts and methods diffuse, endure and decline within academic fields.
Using the JSTOR database, which contains more than 4.5 million academic articles published between 1900 and 2015, Maiers and Napoli tracked the prevalence and movement of concepts and methods through a textual analysis of articles.
They explored two different methods for tracking concepts and ideas within this corpus:
- A supervised approach to identify words and concepts of interest
- An unsupervised topic modeling approach
Maiers and Napoli developed a typology of the patterns by which concepts and methods move through individual disciplines and spread across disciplines.
