Colbert v2 is literally listed in the beir sparse leaderboards...
Sparse refers to the embedding vector(s), not the model
And ranking/reranking refers to the same thing, but its still distinct from retrieval, which was my point

ColBERT is both on the dense and the sparse leaderboard :^)
I would describe it as a (sparse?) collection of dense embeddings per query/document, so it's hard to classify it between the two (although I'm leaning more toward the dense categorization).

splade-v2 and sparta are exclusively on the sparse leaderboards, and they uses bert
the point is dispelling the notion that sparse retrieval somehow = no dl involved. it's conflating dense retrieval with neural retrieval
