Ctm topic modelling
WebApr 18, 2024 · The Structural Topic Model (STM) is a form of topic modelling specifically designed with social science research in mind. STM allow us to incorporate metadata into our model and uncover how … WebTopic modeling can be used to classify or summarize documents based on the topics detected or to retrieve information or recommend content based on topic similarities. The topics from documents that NTM learns are characterized as a latent representation because the topics are inferred from the observed word distributions in the corpus.
