如何在 Spacy，正则表达式 python 中修改已识别的名词短语 A 到 B 或 C--->A 到 B 或 A 到 C

Question

I have identified the noun phrase A to B or C by using spaCy rule-based matcher. However, I want to modify the obtained result:

A to B or C--->A to B or A to C

And make sure that the original meaning is correct.

How can I do this in python by using regular expression + spacy or nltk or anything else is helpful?

Thanks!

Answer 1

I would use re.sub as follows:

inp = "A to B or C"
output = re.sub(r'\b(\S+) to (\S+) or (\S+)\b', r'\1 to \2 or \1 to \3', inp)
print(output)  # A to B or A to C
