(1, 0.10000000000000002), Python wrapper for Latent Dirichlet Allocation (LDA) from MALLET, the Java topic modelling toolkit This module allows both LDA model estimation from a training corpus and inference of topic distribution on new, unseen documents, using an (optimized version of) collapsed gibbs sampling from MALLET. I am facing a strange issue when loading a trained mallet model in python. Maybe you passed in two queries, so you got two outputs? LDA is a generative probabilistic model that assumes each topic is a mixture over an underlying set of words, and each document is a mixture of over a set of topic probabilities. I’m not sure what you mean. corpus = [id2word.doc2bow(text) for text in texts], model = gensim.models.wrappers.LdaMallet(path_to_mallet, corpus, num_topics=2, id2word=id2word) Currently under construction; please send feedback/requests to Maria Antoniak. Topic coherence evaluates a single topic by measuring the degree of semantic similarity between high scoring words in the topic.
