将字符串列表与文本块匹配

Question

这里是初学者：

我有一段文字：

例如：'hey this is a block of text, for an example, wow looks cool blah blah blah angiotensin enzyme looks cool okay.But what about angiotensin enzym well I dont know.'

还有一个单词列表：['angiotensin enzyme serum', 'some diff enzyme', 'angiotensin enzyme a1']

我的最终目标是从文本块中找到字符串匹配/模糊匹配的单词列表。

我尝试了什么：difflib.get_close_matches

需要输出：'angiotensin enzyme serum'、'angiotensin enzyme a1'

输出顺序不是问题。

对于其他文本块，列表中的其他一些字符串将匹配。块不是常量。

有没有办法做到这一点？

Answer 1

使用fuzzywuzzy（来自 PyPi）：

from fuzzywuzzy import fuzz

text = 'hey this is a block of text, for an example, wow looks cool blah blah blah angiotensin enzyme looks cool okay.But what about angiotensin enzym well I dont know.'

words = ['angiotensin enzyme serum', 'some diff enzyme', 'angiotensin enzyme a1']

matches = [w for w in words if fuzz.partial_ratio(text, w) > 70.]

显然，您需要调整阈值以适应，但在此示例中这些值被很好地分开：

>>> print(matches)
['angiotensin enzyme serum', 'angiotensin enzyme a1']

>>> for w in words:
...     print(w, fuzz.partial_ratio(text, w))
... 
angiotensin enzyme serum 83
some diff enzyme 56
angiotensin enzyme a1 90
