Bridge previewMaterialized ranking run

Candidate bridge papers with measured cross-cluster signal, presented as a separate experimental view.

Bridge evidence is experimental and run-specific. This page pins Bridge to rank-5a7efa5ca3; canary ML serving requires limit=20.

Papers come from a materialized ranking run. The explanations reflect the recorded signal weights for the resolved run. The undercited family is scoped to a frozen low-citation candidate pool for the same corpus snapshot.

Snapshot

Snapshot 2026-05-21

Showing 20 papers from a materialized bridge ranking run; 20 include topic labels.

Topic labels are imported metadata and can be noisy; use them as coarse navigation hints, not authoritative classifications.

Focus paper: https://openalex.org/W4413720412 is not in the current top 20 rows for this view, but the run context is still pinned while you switch families.

Technical run metadata

Resolved run label: shadow-gen-bridge-score-diagnostic-v1.

Ranking mode: materialized_heuristic.

Bounded Bridge scorer serving is eligible only for Bridge requests with limit=20 and the pinned Bridge run; otherwise the API uses materialized heuristic order.

Bridge run pin: rank-5a7efa5ca3. The global product run label is not sent for Bridge requests. Resolved run: rank-5a7efa5ca3; snapshot: source-snapshot-shadow-generalization-v1-20260521.

Storage provenance: materialized family rows are read from paper_scores. Result ordering is final_score desc, work_id asc. The undercited pool definition is documented in docs/candidate-pool-low-cite.md.

Bridge preview shows measured cross-cluster signal for the resolved run. Some rows may not pass the optional bridge gate; use the eligible-only view when you want to hide those rows.

How this Bridge list is ranked

  • Ordering uses recent attention, topic momentum, and topic breadth penalty.
  • Cross-cluster signal may be weighted for this family depending on the ranking run.
  • Semantic match is shown when present but not used in default ordering.

Used in ordering: Recent attention, Topic momentum, Topic breadth penalty
Measured only (transparency): Semantic match, Cross-cluster signal
Full Bridge run details are available in Technical run metadata.

Current ML boundary

Emerging can be reordered by the bounded ML scorer only when the backend rollout gate is enabled. Bridge and Under-cited are not served by that scorer; their order comes from materialized ranking rows.

Heuristic baseline

The rule-only undercited list (/api/v1/recommendations/undercited) uses the same pool definition but is not tied to a corpus snapshot. For snapshot-scoped A/B against the ranked undercited family, use Evaluation.
