如何删除不是人名的单词

Question

我想从文本文件中获取person的名称我使用nltk返回名称以及不是名称的单词：

def extract_names(text):
    tokens = nltk.tokenize.word_tokenize(text)
    pos = pos_tag(tokens)
    sentt = ne_chunk(pos, binary = False)
    person_list = []
    person = []
    name = ""
    for subtree in sentt.subtrees(filter=lambda t: t.label() == 'PERSON'):
        for leaf in subtree.leaves():
            person.append(leaf[0])
        if len(person) > 1: #avoid grabbing lone surnames
            for part in person:
                name += part + ' '
            name = remove_useless_name(name)
            if name[:-1] not in person_list:
                person_list.append(name[:-1])
            name = ''
        person = []

    return person_list

我想删除那个不是名字的单词，我应该使用哪个方法来删除单词。 输入如

"Sunder Pichai"
"View Profile"
"Risk Management"

示例输出：

"Sunder Pichai"

也许使用字典，并检查名称的所有部分是否是真正的单词和/或姓氏是否为已知名称
