Determining string intersection (embeddings) between two narrative (text) fields

[twinpiques]

Have you looked at difflib? I think it would give better answers than sets, but it would be a lot slower. If you decided to go with set intersections, I would look at removing stop words before comparing.

I had not considered difflib, but I've been researching it since your post. Thank you for the suggestion.
I think it could be a viable option, so I'm going to try both methods.
