如何在python中使用正則表達式從字符串中提取特定單詞

Question

我有兩個包含單詞及其類型的字符串：

text1 = 'Mau/VBT ngasih/NN hadiah/NN untuk/IN Anniv/NN ,/, Graduation/NN ,/, Birthday/NN ,/, Wedding/NN ,/, dll/VBT ?/. Nih/DT ,/, ada/VBI hadiah/NN kece/JJ yang/SC at/IN Yasmin/NNP 33/CDP'
text2 = 'Yang/SC kelaparan/NN habis/VBI latihan/NN ilovenaylambem/NN at/IN Jl/NNP Halimun/NNP Raya/NNP ,/, Menteng/NN'

我喜歡將帶有/NN標簽的任何單詞形式的單詞提取到帶有/NNP和/CDP標簽的單詞中。 到目前為止，這是我的代碼（仍然僅適用於/NNP標簽）：

import re

def entityExtractPreposition(text):
    text = re.findall(r'([^\s/]*/IN\b[^/]*(?:/(?!IN\b)[^/]*)*/NNP\b)', text)
    return text

text1 = 'Mau/VBT ngasih/NN hadiah/NN untuk/IN Anniv/NN ,/, Graduation/NN ,/, Birthday/NN ,/, Wedding/NN ,/, dll/VBT ?/. Nih/DT ,/, ada/VBI hadiah/NN kece/JJ yang/SC at/IN Yasmin/NNP 33/CDP'
prepo1 = entityExtractPreposition(text1)

text2 = 'Yang/SC kelaparan/NN habis/VBI latihan/NN ilovenaylambem/NN at/IN Jl/NNP Halimun/NNP Raya/NNP ,/, Menteng/NN'
prepo2 = entityExtractPreposition(text2)

print text1
print prepo1
print ''
print text2
print prepo2

到目前為止的代碼結果：

Mau/VBT ngasih/NN hadiah/NN untuk/IN Anniv/NN ,/, Graduation/NN ,/, Birthday/NN ,/, Wedding/NN ,/, dll/VBT ?/. Nih/DT ,/, ada/VBI hadiah/NN kece/JJ yang/SC at/IN Yasmin/NNP 33/CDP
['at/IN Yasmin/NNP']

Yang/SC kelaparan/NN habis/VBI latihan/NN ilovenaylambem/NN at/IN Jl/NNP Halimun/NNP Raya/NNP ,/, Menteng/NN
['at/IN Jl/NNP Halimun/NNP Raya/NNP']

如我們所見，對於第一個字符串（ text1 ）， entityExtractPreposition仍然無法獲得33/CDP 。 如何通過text1中的/CDP標記或text2中的/NNP來使entityExtractPreposition工作正常？

預期結果是：

Mau/VBT ngasih/NN hadiah/NN untuk/IN Anniv/NN ,/, Graduation/NN ,/, Birthday/NN ,/, Wedding/NN ,/, dll/VBT ?/. Nih/DT ,/, ada/VBI hadiah/NN kece/JJ yang/SC at/IN Yasmin/NNP 33/CDP
['at/IN Yasmin/NNP 33/CDP']

Yang/SC kelaparan/NN habis/VBI latihan/NN ilovenaylambem/NN at/IN Jl/NNP Halimun/NNP Raya/NNP ,/, Menteng/NN
['at/IN Jl/NNP Halimun/NNP Raya/NNP']

謝謝

\b[^\s/]+/IN\b(?:(?!/IN\b).)*/(?:NNP|CDP)\b
