How to calculate the sentence similarity using word2vec model of gensim with python

Question

According to the Gensim Word2Vec, I can use the word2vec model in gensim package to calculate the similarity between 2 words.

e.g.

trained_model.simi         


        

Answer 1

You can just add the word vectors of one sentence together. Then count the Cosine similarity of two sentence vector as the similarity of two sentence. I think that's the most easy way.
