Description

Currently, I am calculating the Coherence of a bertopic model using the gensim. For this I need the n_grams from each text of the corpus. Is it possible? The function used by gensim waits for the corpus and topics, and the topics are tokens that must exist in corpus.

cm = CoherenceModel(topics, corpus, dictionary, coherence='u_mass')

Thanks in advance.

Research direction

No repository files or tests are named. Start by tracing how BERTopic provides topic words and how the shown gensim CoherenceModel call expects the corpus, dictionary, and topics; done would be a clear supported approach, with an example or test demonstrating coherence calculation.
