Dynamic topic modelling
WebDynamic topic modeling (DTM) ( Blei and Lafferty, 2006) provides a means for performing topic modeling over time. Internally using Latent Dirichlet Allocation (LDA) ( Blei et al., 2003 ), it creates a topic per time slice. By applying a state-space model, DTM links topic and topic proportions across models to “evolve” the models over time. WebDynamic Topic Modeling (DTM) (Blei and Lafferty 2006) is an advanced machine learning technique for uncovering the latent topics in a corpus of documents over time. The goal of this project is to provide …
