WebDynamic topic models (DTM) captures the evolution of topics in a sequentially organized movies. In the DTM, we divide the data by time slice, e.g., by year. We model the movies of each slice with a K-component topic model, where the topics associated with slice t evolve from the topics associated with slice t-1.
