缩写词和带连字符的单词的打印

Question

我需要先识别句子中的所有缩写词和带连字符的单词。它们需要在被识别时打印出来。我的代码似乎不能很好地用于此标识。

import re

sentence_stream2=df1['Open End Text']
for sent in sentence_stream2:
    abbs_ = re.findall(r'(?:[A-Z]\.)+', sent) #abbreviations
    hypns_= re.findall(r'\w+(?:-\w+)*', sent) #hyphenated words

    print("new sentence:")
    print(sent)
    print(abbs_)
    print(hypns_)

我语料库中的一个句子是：使用云数据分析环境的 API 和事件驱动架构的 DevOps 自助服务 BI

这个输出是：

new sentence:
DevOps with APIs & event-driven architecture using cloud Data Analytics environment Self-service BI
[]
['DevOps', 'with', 'APIs', 'event-driven', 'architecture', 'using', 'cloud', 'Data', 'Analytics', 'environment', 'Self-service', 'BI']

预期输出为：

new sentence:
DevOps with APIs & event-driven architecture using cloud Data Analytics environment Self-service BI
['APIs','BI']
['event-driven','Self-service']

Answer 1

您的缩写规则不匹配。你想找到超过 1 个连续大写字母的单词，你可以使用的规则是：

abbs_ = re.findall(r'(?:[A-Z]{2,}s?\.?)', sent) #abbreviations

这将匹配 API 和 BI。

t = "DevOps with APIs & event-driven architecture using cloud Data Analytics environment Self-service BI"

import re

abbs_ = re.findall(r'(?:[A-Z]\.)+', t) #abbreviations
cap_ = re.findall(r'(?:[A-Z]{2,}s?\.?)', t) #abbreviations
hypns_= re.findall(r'\w+-\w+', t) #hyphenated words fixed

print("new sentence:")
print(t)
print(abbs_)
print(cap_)
print(hypns_)

输出：

DevOps with APIs & event-driven architecture using cloud Data Analytics environment Self-service BI
[]  # your abbreviation rule - does not find any capital letter followed by .
['APIs', 'BI'] # cap_ rule
['event-driven', 'Self-service']  # fixed hyphen rule

这很可能找不到像

这样的所有缩写

t = "Prof. Dr. S. Quakernack"

因此您可能需要使用更多数据和 f.e 对其进行调整。 http://www.regex101.com

Answer 2

我建议：

abbs_ = re.findall(r'\b[A-Z]+s?\b', sent) #abbreviations
hypns_ = re.findall(r'\w+(?:-\w+)*', sent) #hyphenated words

Answer 3

"As you know, I got all As in my course".

"As"是缩写吗？如果不是，那么您需要丢弃单个大写字母后跟或不跟 Ss，并且只收集至少对，可选地后跟一个 s，如 APIs.所以，

abbs_ = re.findall(r'\b(?:[A-Z][A-Z]+s?)\b', sent) #abbreviations

需要 \b 以确保您不会因为中间的那对 AG 而收获诸如 ImNotAGirl 之类的东西。

然后你必须得到缩写：一个单词（\w+），然后是至少一个连字符-单词序列：

hypns_= re.findall(r'\b(?:\w+(-\w+)+)\b', sent) #hyphenated words
