NLTK is a framework that is widely used for topic modeling and text classification. kwx. Improved models: For English documents the default is now: "paraphrase-MiniLM-L6-v2" For Non-English or multi-lingual documents the default is now: "paraphrase-multilingual-MiniLM-L12-v2" Both models show not only great performance but are much faster! Choose the topic with the highest score to determine it’s topic. As an example: According to the model, the first article belongs to 0th topic and the second one belongs to 6th topic which seems to be the case. This post showed you how to train your own topic modeling model and use it to identify the topics in your dataset. It even supports visualizations similar to LDAvis!
