As part of the review, The Digital Humanities Institute at the University of Sheffield applied concept modelling techniques to a curated corpus of 1,900 journal articles from the period 1968 to 2017. Concept modelling is a computational linguistic process that involves identifying the emergence of concepts, or key ideas, via lexical relationships. For the purposes of the review, lexical relationships were limited to high frequency co-occurrences of terms as pairs and trios. The process is entirely data driven and resulted in 2 million rows of data.
This website provides access to the top 50 most frequently occurring pairs and trios through a series of data visualisations.
Concept modelling was developed by the University of Sheffield’s School of English and The Digital Humanities Institute as part of the Linguistic DNA project.
