WebDec 20, 2024 · Working with the gensim library makes computing these coherence measures for topic models fairly simple. I personally choose to implement C_v and C_umass. The coherence score for C_v ranges from 0 (complete incoherence) to 1 (complete coherence). Values above 0.5 are fairly good, according to John McLevey … WebDec 7, 2016 · Hi, I already talked with Ólavur about this and would like to suggest adding Structural Topic Models to gensim.
