The review protocol in the file Review_protocol.pdf summarises the research steps taken in the analyses described in sections 4.1-4.5 of the paper and links these analyses to the respective R-scripts.

a) 0_load_and_clean_data.R – prepares two data-frames (MCE, MCESUS) used in the analysis in scripts 1-4; is sources from scripts 1-4.; requires all .bib files in the folder /data in the working directory
b) 1_thematic_maps.R – creates the four thematic maps; requires 0_load_and_clean_data.R
c) 2_conceptual_structure.R – runs the Multiple Correspondence Analysis and k-means clustering; requires 0_load_and_clean_data.R
d) 3_correlated_topic_model.R – fits the correlated topic model; requires 0_load_and_clean_data.R
e) 4_historiographic_analysis.R - performs the historiographic network analysis that is used also as a basis for the subsequent qualitative analysis; requires 0_and_clean_data.R

The two data frames MCE and MCESUS created via 0_load_and_clean_data.R and that are used in scripts 1-4 both contain following variables:

The datasets a)-n) in the folder “/data” in the working directory are BibTeX files extracted from the Web of Science and Scopus databases. The keywords and settings used for extracting them can be found in the script 0_load_and_clean_data.R and in the file Review_protocol.pdf. The two files "MCE.RDS" and "MCESUS.RDS" in the folder "/data" comprise the two dataframes used in scripts 1-4, and instead of creating them from new with script 0, they can be loaded directly in scripts 1-4.

The files a)-d) in the folder "/networks" are vector graphs of the thematic networks that are underlying the four thematic maps in section 4.1. Files e)-h) are the corresponding network files were used to plot the graphs.
