Thanks for the PR @Raya679!
🍒 Please see the comments.
Aside from those, I believe doing the termURL look up the way it is at the moment would require the user to know the exact wording of the term labels and therefore allows for no flexibility.
For example if a user input has a typo or if a user input uses an acronym for a term (MoCA or moca for Montreal Cognitive Assessment Tool) the look up fails to find the correct term and returns None.
I believe this is one of the most important steps of the project and we should leverage every tool to make term look up to be as flexible as possible. Let me know what you think.

I left one small comment other than that this is good to go 🧑‍🍳
Side note, how did you create the abbreviations?

Hi @rmanaem thanks for the review!! Regarding the abbreviations I had created them using llama3 itself similar to what was done in the annotation tool ai
