一，代码

# Word2Vec
import os
import jieba
# 数据训练与分析
from gensim.models import word2vec

org_txt = './3b.txt'
cut_txt = './3b_jieba.txt'
model_name = './3b.model'

"""
# 准备数据
with open(org_txt, 'r') as fp:
    if os.path.exists(cut_txt):
        os.remove(cut_txt)
    lines = fp.readlines()
    for line in lines:
        seg_list = jieba.cut(line)
        with open(cut_txt, 'a',encoding='utf-8') as ff:
            ff.write(' '.join(seg_list))


# 加载语料
sentences = word2vec.Text8Corpus(cut_txt)
# 训练模型
model = word2vec.Word2Vec(sentences)

# 选出最相近的10个词
for e in model.wv.most_similar(positive=['叶文洁'], topn=10):
    print(e[0], e[1])

# 存储和加载模型
model.save(model_name)
"""

model = word2vec.Word2Vec.load(model_name)

# Word2Vec的其它用途
# 计算两个词的相似度
print(model.wv.similarity('叶文洁', '杨冬'))
# 计算两个集合的相似度
list1 = ['周文王', '秦始皇']
list2 = ['丁仪', '大史']
print(model.wv.n_similarity(list1, list2))

# 选出集合中不同类的词语
list3 = ['叶文洁', '杨冬', '丁仪', '周文王']
print(model.wv.doesnt_match(list3))

# 查看词的向量值
print(type(model.wv['叶文洁']))
print(len(model.wv['叶文洁']))
print(model.wv['叶文洁'])
