Therefore we first calculate a group of mean vectors m iw 1 ,••• ,iw N of all the candidate words with any possible word senses as below , where T is the set of candidate words, N is the capacity of T , w j is a word in T ; is the index for the word senses of w j , and is the number of word senses of w j .
the number of the mean vectors is M = N j=1 k w j .
