How to get vector for a sentence from the word2vec of tokens in sentence

Question

I have generated the vectors for a list of tokens from a large document using word2vec. Given a sentence, is it possible to get the vector of the sentence from the vector of

Answer 1

It is possible, but not from word2vec. The composition of word vectors in order to obtain higher-level representations for sentences (and further for paragraphs and documents) is a really active research topic. There is not one best solution to do this, it really depends on to what task you want to apply these vectors. You can try concatenation, simple summation, pointwise multiplication, convolution etc. There are several publications on this that you can learn from, but ultimately you just need to experiment and see what fits you best.
