從科學出版物中刪除特定的參考文獻，如作者

Question

我之前看到過這個問題： python 從科學論文中刪除參考這與我想做的類似，但我仍然無法弄清楚如何准確假設我的字符串有這樣的參考，例如： Poteete et al。 (2010)如何使用 python 中的正則表達式從字符串中刪除它？

我嘗試過的與上一個問題相似，但也許我忘記了某事：

sentence = "Moreover, we elaborate on how these methods have led to improved insights into the theoretical framework proposed by  Poteete et al. (2010)"
sentence = re.sub(r'(?:[\w \.])+[0-9]{4}','',sentence)

有什么想法嗎？ 非常感謝你的幫助。

Answer 1

如果名稱以大寫字符 AZ 開頭：

[A-Z]\w*(?: +\w+)*\. \(\d{4}\)

• [AZ]\w*匹配一個字符 AZ 和可選單詞 char
• (?: +\w+)*可選擇重復 1+ 個空格和 1+ 個單詞字符
• \. 匹配.
• \(\d{4}\)匹配括號之間的 4 位數字

除了匹配空格，您還可以使用\s但它也可以匹配換行符。

正則表達式演示

import re
 
sentence = "Moreover, we elaborate on how these methods have led to improved insights into the theoretical framework proposed by  Poteete et al. (2010)"
sentence = re.sub(r'[A-Z]\w*(?: +\w+)*\. \(\d{4}\)', '', sentence)
print (sentence)

Output

Moreover, we elaborate on how these methods have led to improved insights into the theoretical framework proposed by  

Answer 2

重新進口

s = "Moreover, we elaborate on how these methods have led to improved insights into the theoretical framework proposed by Poteete et al. (2010) and Someone et al. (2010) and something"

print (re.sub(r'[A-Z][a-z]+\set al\.\s\([0-9]{4}\)','',s))

Output：

Moreover, we elaborate on how these methods have led to improved insights into the theoretical framework proposed by  and  and something

在這里您可以檢測到“等”。 后跟日期，前面是第一個字母為大寫的名稱。然后將其刪除。

不用說這些操作大多是自定義的，具體取決於您的特定論文、編輯器格式化參考的方式等。所以無論如何它一定很痛苦。
