Text mining has a wide range of applications in education. In this paper, we review Latent Dirichlet Allocation (LDA) - a topic model. In addition, we also introduce a collapsed Gibbs sampling algorithm for parameter estimation. An example of examining similarities between a journal article and its references is demonstrated.
