【解决方案1】：

假设您有任何 word2vec 实用程序为 word2vec：

import numpy as np

words1 = sentence1.split(' ')
words2 = sentence2.split(' ')

#The meaning of the sentence can be interpreted as the average of its words
sentence1_meaning = word2vec(words1[0])
count = 1
for w in words1[1:]:
    sentence1_meaning = np.add(sentence1_meaning, word2vec(w))
    count += 1
sentence1_meaning /= count

sentence2_meaning = word2vec(words2[0])
count = 1
for w in words2[1:]:
    sentence2_meaning = np.add(sentence2_meaning, word2vec(w))
    count += 1
sentence2_meaning /= count

#Similarity is the cosine between the vectors
similarity = np.dot(sentence1_meaning, sentence2_meaning)/(np.linalg.norm(sentence1_meaning)*np.linalg.norm(sentence2_meaning))
