    sheet1.write(i + 1, 7, pom_list[i]['tag'])
xl.save("qing_tag.xlsx")
# print(pom_list)

结果如下：类别之间用","分割

分词

from pyhanlp import *


#1.分词
sentence = "我爱北京天安门，天安门上放光彩"
#返回一个list，每个list是一个分词后的Term对象，可以获取word属性和nature属性，分别对应的是词和词性
terms = HanLP.segment(sentence )
for term in terms:
    print(term.word,term.nature)

关键词提取与自动摘要

document = "水利部水资源司司长陈明忠9月29日在国务院新闻办举行的新闻发布会上透露，" \
           "根据刚刚完成了水资源管理制度的考核，有部分省接近了红线的指标，" \
           "有部分省超过红线的指标。对一些超过红线的地方，陈明忠表示，对一些取用水项目进行区域的限批，" \
           "严格地进行水资源论证和取水许可的批准。"

#提取document的两个关键词
print(HanLP.extractKeyword(document, 2))

#提取ducument中的3个关键句作为摘要
print(HanLP.extractSummary(document,3))

依存句法分析

#依存句法分析
print(HanLP.parseDependency("徐先生还具体帮助他确定了把画雄鹰、松鼠和麻雀作为主攻目标。"))

 

 短语提取

text = "在计算机音视频和图形图像技术等二维信息算法处理方面目前比较先进的视频处理算法"
phraseList = HanLP.extractPhrase(text, 10)
print(phraseList);
