增加权重

important_dic = {'预付卡'}

weight = 3              #可以修改，也可以再字典里添加权值

k=0

for word in set(sent):

    if word in important_dic:

        k = weight

    else:

        k = 0



    if word in dic:

        index = dic.index(word)

        vec[index] = 1+k

        print(word)



    else:

        print(word + 'is not in vocabulary!! Will ignore this word!!')

        continue

    list = model.wv.most_similar(word, topn=n)

    for tuple in list:

        word = tuple[0]



        similarity = tuple[1]+k

            # similarity = 1

        #print(tuple)

        index = dic.index(word)

        vec[index] = similarity



增加了权重，进行权重增加的词会在相似度匹配中获得较大的影响力
