python - 如何使用nltk从字符串中提取名称

我正在尝试从非结构化字符串中提取名称（印第安人）。
我的代码来了：

text = "Balaji Chandrasekaran Bangalore |  Senior Business Analyst/ Lead Business Analyst An accomplished Senior Business Analyst with a track record of handling complex projects in given period of time, exceeding above the expectation.

if text != "":
    grammar = """PERSON: {<NNP>}"""
    chunkParser = nltk.RegexpParser(grammar)
    tagged = nltk.pos_tag(nltk.word_tokenize(text))
    tree = chunkParser.parse(tagged)

    for subtree in tree.subtrees():
        if subtree.label() == "PERSON":
            pronouns.append(' '.join([c[0] for c in subtree]))

    print(pronouns)

['Balaji'、'Chandrasekaran'、'Bangalore'、'|'、'Senior'、'Business'，
'分析'，'/'，'领导'，'业务'，'分析师'，'高级'，'业务'，
‘分析师’、‘成功’、‘开发’、‘生命周期’、‘SDLC’，
“敏捷”、“业务”、“需求”、“分析”、“项目”，
“管理”、“UML”、“规范”、“UI”、“UX”、“线框”，
“设计”、“功能”、“规范”、“测试”、“方案”，
“创建”、“SharePoint”、“管理”、“工作”、“历史”、“高级”，
“业务”、“分析师”、“八月”、“当前”、“技术”、“金奈”，
“翻译”、“CRM”、“财务”、“物流”、“运营”，
“联运”、“教育”、“学士”、“工程”、“电子”，
“沟通”，“成就”，“成功”，“地中海”，
“船舶”，“公司”，“理学硕士”，“格鲁吉亚”，“理学硕士”，“柬埔寨”，“理学硕士”，“理学硕士”，
“南方”，“成功”，“股份”，“理学硕士”，“日内瓦”，“瑞士”，“Pre”，
“研究”、“一般”、“设计”、“功能”、“规范”、“O”，
“业务”、“分析师”、“论坛”、“业务”]
但实际上我只需要得到巴拉吉·钱德拉塞卡兰，我甚至试着使用斯坦福德内尔库，但没有选到巴拉吉·钱德拉塞卡兰
有谁能帮我从unstructure字符串中提取名字，或者给我推荐一些好的教程。
提前谢谢你。

最佳答案

就像我在评论中所说的，你必须为印度名字创建自己的语料库，并根据它测试你的文本。NLTK的书教你如何在Chapter 2中做到这一点（确切地说是1.9节）。

from nltk.corpus import PlaintextCorpusReader

# You can use a regular expression to find the files, or pass a list of files
files = ".*\.txt"

new_corpus = PlaintextCorpusReader("/path/", files)
corpus  = nltk.Text(new_corpus.words())
