How to extract sub sentences from sentence mentioning a particular subject?

Question

I am trying to solve an NLP problem. For a given sentence like :

"The Pasta was delicious, the Pizza was average"

I want to extract the sentiment attached to food items. Having built my own NER model, I am able to extract Pasta and Pizza and hence the sentences containing them. But using a sentiment analyser on the entire sentence would be wrong in this case

EXPECTED OUTPUT:

Pasta - Good score Pizza - Average score

CURRENT OUTPUT:

Pasta - Kinda Good Score Pizza - Kinda Good Score

I know I am getting this output because I am considering the same sentence for getting the sentiment attached to both the subjects in hand.

Is there a way to extract the sub sentence like "Pasta was good" and "Pizza was average" to associate sentence with each item instead of whole sentences which I am currently doing ?

Answer 1

If you would know the target(s) (pasta, pizza) and the sentiment features (good, bad, etc), you could try to catch the feature that is closest to the target in a sentence.

But to say more, it really is necessary to see more of your sentences to understand the structure.
