Ranking orders candidates using signals such as lexical match, vector similarity, authority, freshness, graph distance, and access. The weights should reflect the task rather than one universal score.

Retrieval Ranking Balances Multiple Signals

Entity resolution decides whether records denote the same entity using identifiers, attributes, relationships, and uncertainty. False merges can be more damaging than temporary duplicates.

Entity Resolution Is Evidence-Weighted

A grounded answer links each material claim to evidence that actually supports it. Citation presence is insufficient when a source is unrelated, contradicted, or inaccessible to the user.

Grounded Answers Bind Claims to Evidence

Lexical search captures exact terms, vectors capture semantic resemblance, and graph traversal captures structured relationships. Fusion should be evaluated against the task and preserve each signal's provenance.
