Abstract

In recent years, the number of published scientific papers has largely increased. The huge amount of text in scientific papers is flowing relevant information that can lead to significant opportunities for various industries and organizations. Researchers and decision-makers need to analyse published papers to access to relevant information. The use of automatic techniques such as topic modeling becomes a necessary requirement to capture hidden semantic structure in a collection of documents. However, the literature lacks surveys that indicate appropriate topic modeling techniques to analyze a corpus of scientific papers. The aim of this research is to compare and discuss three topic modeling techniques: Latent Semantic Analysis (LSA), Latent Dirichlet Allocation (LDA) and Correlated Topic Model (CTM) applied on a corpus of scientific papers in the field of marketing. Objective and subjective evaluation are performed. The objective evaluation is based on machine learning metrics while the subjective evaluation is based on expert opinion to evaluate the quality of the best topic models retrieved by LSA, LDA and CTM. The obtained results are presented and discussed according to several quality criteria.

In this work, we choose the optimal number for LDA equal to 18, for CTM equal to 14 and for LSA equal to 18. Tables 10, 11 and 12 show the latent topics generated by LSA, LDA and CTM respectively.
