Abstract: A thermodynamic approach has been applied to solving the problem of selecting the number of clusters/topics in topic modeling. The main principles of this approach are formulated and the behavior of topic models during temperature variations is studied. Using thermodynamic formalism, the existence of the entropy phase transition in topic models is shown and criteria for the choice of optimum number of clusters/ topics are determined.
