如何使用NLTK將文本分割爲段落nltk.tokenize.texttiling？

Question

我發現這個Split Text into paragraphs NLTK - usage of nltk.tokenize.texttiling?解釋瞭如何將文本輸入到文本中，但是我無法實際返回由段落/主題更改標記的文本，如文本http://www.nltk.org/api/nltk.tokenize.html下所示。

當我將我的文本輸入到文本文件中時，我得到的是未經過處理的文本，但是作爲列表，這對我來說沒有用處。

tt = nltk.tokenize.texttiling.TextTilingTokenizer(w=20, k=10,similarity_method=0, stopwords=None, smoothing_method=[0], smoothing_width=2, smoothing_rounds=1, cutoff_policy=1, demo_mode=False) 

    tiles = tt.tokenize(text) # same text returned 

我已經是遵循這個基本結構

From: X 
    To: Y        (LOGISTICS) 
    Date: 10/03/2017 

    Hello team,      (INTRO) 

    Some text here representing 
    the body       (BODY) 
    of the text. 

    Regards,       (OUTRO) 
    X 

    *****DISCLAIMER*****    (POST EMAIL DISCLAIMER) 
    THIS EMAIL IS CONFIDENTIAL 
    IF YOU ARE NOT THE INTENDED RECIPIENT PLEASE DELETE THIS EMAIL 

如果我們把這個郵件字符串s，它看起來像

s = "From: X\nTo: Y\nDate: 10/03/2017 Hello team,\nSome text here representing the body of the text. Regards,\nX\n\n*****DISCLAIMER*****\nTHIS EMAIL IS CONFIDENTIAL\nIF YOU ARE NOT THE INTENDED RECIPIENT PLEASE DELETE THIS EMAIL" 

電子郵件我想要做的就是迴歸這5段/字符串s - LOGISTICS，INTRO，BODY，OUTRO，POST電子郵件免責聲明 - 單獨所以我可以刪除所有內容，但T的BODY分機。如何使用nltk文本分別返回這5個部分？

***並非所有電子郵件都遵循相同的結構或具有相同的措辭，所以我不能使用正則表達式。

怎麼樣使用splitlines？或者你需要使用nltk軟件包嗎？

email = """ From: X 
    To: Y        (LOGISTICS) 
    Date: 10/03/2017 

    Hello team,      (INTRO) 

    Some text here representing 
    the body       (BODY) 
    of the text. 

    Regards,       (OUTRO) 
    X 

    *****DISCLAIMER*****    (POST EMAIL DISCLAIMER) 
    THIS EMAIL IS CONFIDENTIAL 
    IF YOU ARE NOT THE INTENDED RECIPIENT PLEASE DELETE THIS EMAIL""" 

y = [s.strip() for s in email.splitlines()] 

print(y)
