如何在python的文本分析中找到连接词？

Question

I wanted to check the connection between 2 words in text analytics in python.currently using NLTK package in python.

For example "Text = " There are thousands of types of specific networks proposed by researchers as modifications or tweaks to existing models"

here if i input as networks and researchers , then i should get output as "Proposed by" or "networks proposed by researchers"

Answer 1

You could Regex match between the two words

import re

word_one = "networks"
word_two = "researchers"

string = "There are thousands of types of specific networks proposed by researchers as modifications or tweaks to existing models"

result = re.search(f'{word_one}(.+?){word_two}', string)
print(result.group(1))

Answer 2

Tom's answer is cleaner. Here is my answer without additional libraries

Find the locations of each word, then use those locations to extract it

text = "There are thousands of types of specific networks proposed by researchers as modifications or tweaks to existing models"

word1 = "networks"
word2 = "researchers"

start = text.find(word1)
end = text.find(word2)

if start != -1 and end != -1 and start < end:
    print(text[start + len(word1):end])
