Find similarity between sentences

Thanks so much for the great work and nice documentation!

I have a question regarding using the sense2vec to find the similarity score between 2 sentences. For example, "What is the color of the airplane?" and "what are the colors of these planes" should have a very high similarity score.

I found the related section in your document discussing how to achieve this for words, but didn't find any for sentences.

Could you tell me where can I find the related information? Thanks ahead!
