Webdynamic topic model (cDTM), which is an extension of the discrete dynamic topic model (dDTM) [2]. Given a sequence of documents, we infer the latent topics and how they change through the course of the collection. The dDTM uses a state space model on the natural pa-rameters of the multinomial distributions that repre-sent the topics.
