Python Gensim: how to calculate document similarity using the LDA model? Depends what similarity metric you want to use. Cosine similarity is universally useful & built-in: sim = gensim.matutils.cossim (vec_lda1, vec_lda2) Hellinger distance is useful for similarity between probability distributions (such as LDA topics): import numpy as np ...

Document similarity – Using gensim Doc2Vec. Gensim Document2Vector is based on the word2vec for unsupervised learning of continuous representations for larger blocks of text, such as sentences, paragraphs or entire documents. This is an implementation of Quoc Le & Tomáš Mikolov: “Distributed Representations of Sentences and Documents ”.
1 gensim.similarities.Similarity returns the cosine similarity between the documents. en.wikipedia.org/wiki/Cosine_similarity So, it is a measure of the angle between documents and expressing it as a percentage probably doesn't make sense.
