CALL NUMBER: deep_dense_retrieval.rrf_fusion_score
DEFINITION: The sum of reciprocal rank values for a given document across all contributing rank lists; the document's position in the fused ranking is determined by descending fusion score.
Invoke this skill to understand rrf_fusion_score down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
THE RELATIVE ROOT (the import cone, by lib)
from deep_dense_retrieval
- rrf_final_ranking (d1): The merged document list produced by sorting all candidates in descending order by their fusion scores, yielding a unified cross-system ranking that reflects all input retrieval evidence
CONSUMERS (what needs this)
rrf_document_candidate, rrf_fusion_score, rrf_reciprocal_rank_score, rrf_weighted_rrf
Projected from the retrieval augmented generation architecture patterns KB (207 concepts / 225 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.
