Identification of Topics and Their Evolution in Management Science: Replicating and Extending an Expert Analysis Using Semi-Automated Methods

Latent Dirichlet allocation (LDA) is a popular generative probabilistic model that enables researchers to analyze large semantic datasets; however, few open-source software tools with Graphical User Interfaces (GUIs) are available to researchers. This study identifies an open-source software tool that, in conjunction with a popular electronic spreadsheet software application, can be used to perform topic modeling. A process is developed and evaluated against a pre-existing expert review that examines work published in Management Science on the topics of technological innovation, product development, and entrepreneurship between 1954 and 2004 (Shane and Ulrich, 2004). The process is then replicated using an expanded corpus that includes all articles published in Management Science between 2005 and 2015. The discussion includes an analysis of the process and insights generated by using topic modeling. A replicable process for researchers and suggestions for practitioners are provided.
