Compute the cosine similarity between word vectors for selected words.
similarity(x, words, mode = c("words", "values"))a matrix of cosine similarity scores when mode = "values" or of
words sorted in descending order by the similarity scores when mode = "words".
When words is a named numeric vector, word vectors are weighted and summed
before computing similarity scores.
