Sparse Retrieval

Canonical ID https://id.searchplex.net/sparse-retrieval/

Retrieval using high-dimensional representations in which most feature dimensions have zero weight.

Scope

Traditional lexical representations and learned sparse representations can both be sparse. Sparse retrieval therefore should not be used as a synonym for learned sparse retrieval.

Narrower

Learned Sparse Retrieval

Lexical Retrieval
Dynamic Pruning
