What is chinking in NLP? Where can it be used?

Chinking is nothing but the process of removing the chunk from the chunk which is called as chink. These patterns are normal regular expression which are modifdied and designed to match POS(Part-of-Speech) tag designed to match the sequences of POS tags.

The syntax for this is very similar we just have denote the chink after the chunk with }{ instead of the chunk's {}.

Step 1 - Import the necessary libraries

from nltk.chunk.regexp import tag_pattern2re_pattern

Step 2 - Print the chunk pattern

print("The Chunk Pattern : ", tag_pattern2re_pattern('?<NN.*>+'))

Chunk Pattern :  (<(DT)>)?(<(NN[^\{\}<>]*)>)+
