NLP之TEA：基于SnowNLP实现自然语言处理之对输入文本进行情感分析(分词→词性标注→拼音&简繁转换→情感分析→测试)

NLP分词

sentence = u"今年春节档的电影，我尤其喜欢吴京主演的电影《流浪地球》"
s = SnowNLP(sentence)

print("Segmented words = {}".format(s.words))

Segmented words = ['今年', '春节', '档', '的', '电影', '，', '我', '尤其', '喜欢', '吴', '京', '主演', '的', '电影', '《', '流浪', '地球', '》']

NLP词性标注

for word, tag in s.tags:
    print("Word = {}, Tag = {}\n".format(word, tag))

Tagging:
Word = 今年, Tag = t
Word = 春节, Tag = t
Word = 档, Tag = Ng
Word = 的, Tag = u
Word = 电影, Tag = n
Word = ，, Tag = w
Word = 我, Tag = r
Word = 尤其, Tag = d
Word = 喜欢, Tag = v
Word = 吴, Tag = nr
Word = 京, Tag = nr
Word = 主演, Tag = v
Word = 的, Tag = u
Word = 电影, Tag = n
Word = 《, Tag = w
Word = 流浪, Tag = vn
Word = 地球, Tag = n
Word = 》, Tag = w

NLP情感分析—TEA

print("Sentiment score = {}".format(s.sentiments))

Sentiment score = 0.999991806695989

NLP常见功能(输出拼音、支持方法)

print("Pinyin = {}".format(s.pinyin))

print(dir(s))

Pinyin = ['jin', 'nian', 'chun', 'jie', 'dang', 'de', 'dian', 'ying', '，', 'wo', 'you', 'qi', 'xi', 'huan', 'wu', 'jing', 'zhu', 'yan', 'de', 'dian', 'ying', '《', 'liu', 'lang', 'di', 'qiu', '》']
['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'bm25', 'doc', 'han', 'idf', 'keywords', 'pinyin', 'sentences', 'sentiments', 'sim', 'summary', 'tags', 'tf', 'words']

sentence = u"春節檔的電影，我尤其喜歡吳京主演的電影"
print("简繁转换 = {}".format(s.han))

简繁转换 = 春节档的电影，我尤其喜欢吴京主演的电影

NLP测试

sentence = u"明天早上举行2019届全明星比赛，我会看直播，因为我特别喜欢詹姆斯、韦德、杜兰特、库里"
print("Sentiment score = {}".format(s.sentiments))

sentence = u"明天早上有比赛"
print("Sentiment score = {}".format(s.sentiments))

sentence = u"明天，上海又要下雨，我特别不喜欢下雨的天气！"
print("Sentiment score = {}".format(s.sentiments))
