词性标记 "list-item-marker" 的一些示例是什么？

Question

有哪些例句包含会被标记为 LS（列表项标记）的单词？

此标签用于 spacy，似乎来自 UPENN：

带句点的项目列表是我见过的 LS 项目的方式。这是一个例子：

import spacy
nlp=spacy.load('en_core_web_sm')
doc= nlp('''The system shall:
1) Reprogram software.
2) Reprogram data.
3) Read/write to memory.
4) Lock/unlock flash memory.
5) Clear memory.
6) Range check.''')
print('\n....')

print("Token Attributes: \n", "token.text, token.pos_, token.tag_, token.dep_, token.orth_")
for token in doc:
    # Print the text and the predicted part-of-speech tag
    print("{:<12}{:<12}{:<12}{:<12}{:<12}".format(token.text, token.pos_, token.tag_, token.dep_, token.orth_))

输出：

....
Token Attributes: 
 token.text, token.pos_, token.tag_, token.dep_, token.orth_
