“…Content analysis and specifically text mining as a specific methodology for discovering knowledge from a large amount qualitative textual data, for which Ramya et al (2017) presented different techniques and framework, have a wide range of successful applications in various fields of science including engineering (e.g., text-mining patents for biomedical knowledge (Rodriguez-Esteban & Bundschus, 2016), social media users' perceptions of the carbon-neutral city (Zeng et al, 2022)), health care (e.g., pre-impressions of COVID-19 vaccination among medical stuff by Mori et al (2022), management (e.g., new product idea identification (Christensen et al, 2017), and politics (Charalampakis et al, 2016). By now, using such techniques is also an accepted way of carrying out bibliometric analyses, too, see for instance, Popescu and Zaharia's (2019) work since the limitations of "traditional" content analysis (i.e., it "involves subjective human interpretation, as a research team must either formulate a classification scheme and apply it manually or train coders generally based on deep learning" (Barbierato et al, 2022, p. 214)) can be overcome by lexical analysis, which helps "reduce subjective interpretation" (Lai & To, 2015, p. 140) due to the subjective definitions of categories and/or differences between coders.…”
