important_dic = {'預付卡'}
weight = 3              #可以修改，也可以再字典里添加權值
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

增加了權重，進行權重增加的詞會在相似度匹配中獲得較大的影響力
