Connect and share knowledge within a single location that is structured and easy to search.
Proposal: Artificial Intelligence
By retrieval algorithms I mean like text search, (approximate) nearest neighbor search. Those algorithms are not usually found in the textbooks of AI but it seems to me that they are quite relevant.
Quite a few such algorithms are found in some AI textbooks, at least. So I believe they could fit here.
I think this question's answer will be closely related to NLP for how it applies here.
