The data source that we use as input into BibExcel is in RIS format (Scopus output) containing the bibliographic information
of the articles. Our analysis focuses on the following data fields: authors, title, journal, publication year, keywords,
abstract, affiliations, and references. These analyses require reformatting of the RIS file into a number of different formats
and hence producing several file types. Interested readers can refer to Paloviita (2009) and Persson et al. (2009) for more detailed procedure and applications of Bibexcel in bibliometric and statistical analysis. BibExcel can extract the required data
from the data fields of the RIS file, but the extracted data is usually messy with no unique and standardized format. To tackle
this, OpenRefine was used in conjunction with BibExcel to prepare the data for further analysis.
