Text Analysis of ETDs in ProQuest Dissertations and Theses (PQDT) Global (2016-2018)
Abstract The information explosion in the form of ETDs poses the challenge of management and extraction of appropriate knowledge for decision making. Thus, the present study forwards a solution to the above problem by applying topic mining and prediction modeling tools to full-text 263 ETDs submitted to the PQDT Global database during 2016-18 in the field of library science. This study was divided into two phases. The first phase determined the core topics from the ETDs using Topic-Modeling-Tool (TMT), which was based on latent dirichlet allocation (LDA), whereas the second phase employed prediction analysis using RapidMiner platform to annotate the future research articles on the basis of the modeled topics.
