SciDEX — Task: [Atlas] Extract structured scientific claims from

Papers with unclaimed evidence cannot contribute to hypothesis scoring or knowledge graph growth. For 20 papers with full text or abstract available and no entries in paper_claims (SELECT id, pmid, title, abstract FROM papers WHERE id NOT IN (SELECT DISTINCT paper_id FROM paper_claims) AND abstract IS NOT NULL ORDER BY citation_count DESC LIMIT 20): (1) parse abstract for causal/mechanistic claims (gene X causes Y, inhibiting Z reduces W); (2) for each claim: extract subject entity, relation type, object entity, confidence (high/medium/low), and supporting sentence; (3) INSERT INTO paper_claims (paper_id, claim_type, subject, relation, object, confidence, supporting_text); (4) link claims to matching hypotheses (UPDATE hypotheses SET evidence_for=... if claim corroborates). Verification: 20 papers have at least 2 paper_claims each; hypothesis evidence links updated.

Goal

Extract structured scientific claims from papers that currently have no claim extraction output. Claims should include source provenance and support downstream evidence linking, hypothesis evaluation, and search.

Acceptance Criteria

☐ A concrete batch of papers has real structured claims extracted

☐ Each extracted claim includes PMID, DOI, URL, or local paper provenance

☐ claims_extracted is marked only after real extraction or a documented skip

☐ Before/after missing-claims counts are recorded

Approach

Query papers where COALESCE(claims_extracted, 0) = 0.

Prioritize papers with abstracts, full text, PMCID, or DOI.

Use existing paper and LLM tooling to extract concise evidence-bearing claims.

Persist claims and verify provenance and remaining backlog counts.

Work Log

2026-04-28 09:03 UTC — Task 109e0a35 iteration 1 plan

Staleness check: task remains valid. Live DB at session start: 27,527 papers with claims_extracted=0, 1,786 papers with claims_extracted>0, 18,184 paper_claims rows, 3,825 KG edges with edge_type='claim_extraction', and 3,047 evidence_entries with methodology='claim_extraction'.
Prior related work established scripts/extract_paper_claims.py as the durable extraction path and fixed provider failures to leave queue items unmarked; current script includes that behavior.
Plan: run the existing neuro-first provenance-backed extractor for a 30-paper batch, then verify target-paper provenance, subject/object/confidence completeness, duplicate structured tuples, and before/after movement in paper_claims, papers.claims_extracted, knowledge_edges, and claim-extraction evidence links.

2026-04-28 09:13 UTC — Task 109e0a35 iteration 1 execution (30 neuro-priority papers)

Ran scripts/extract_paper_claims.py --limit 30 using the existing neuro-first provenance-backed queue.
27 of 30 candidates received structured claims, with 164 newly inserted paper_claims rows reported and verified. All 27 successful papers were neuro-relevant.
Two papers (23810450, 22179316) returned no claim-worthy structured statements and were correctly marked claims_extracted=-1.
One candidate (30171180) had only a 20-character abstract and returned status='no_abstract'; it remains claims_extracted=0 rather than being falsely marked complete.
No provider failures occurred in this run.

Results:

paper_claims total: 18,184 → 18,348 (+164)
Papers with claims_extracted > 0: 1,786 → 1,813 (+27)
Papers with claims_extracted=0: 27,527 → 27,498 (−29)
Papers missing claims with abstracts: 26,481 → 26,452 (−29)
knowledge_edges with edge_type='claim_extraction': 3,825 → 3,868 (+43 live; extractor reported 45 insert attempts)
evidence_entries with methodology='claim_extraction': 3,047 → 3,077 (+30)
Successful target PMIDs: 22993429,23493481,23150908,23079895,23440789,23692930,23644076,22166416,21176768,21349849,21196395,19449329,19433665,21209185,21374818,21595956,21358643,21385991,19115931,19775776,19020018,18599438,18596894,18547682,18497889,18639365,18276960.

Verification:

Successful target set: 27 papers with claims, 164 total current claim rows, 3-8 rows per paper, incomplete_claims=0, missing_provenance=0, duplicate_groups=0.
For every successful target PMID, papers.claims_extracted equals the current paper_claims row count.
Documented no-claim skips: 23810450 and 22179316 have claims_extracted=-1 and zero claim rows.
Short-abstract skipped candidate: 30171180 has abstract_len=20, claims_extracted=0, and zero claim rows.

2026-04-28 17:45 UTC — Task 782ee3a9 iteration 3 execution (35 neuro-priority papers)

Staleness check: task remains valid. Live DB at session start: 27,659 papers with claims_extracted=0, 1,626 papers with claims_extracted>0, 16,960 paper_claims rows, 3,429 KG edges with edge_type='claim_extraction'.
LLM latency test: 3 sequential calls took 39s (~13s/call). Batch of 35 papers with 1s sleep between papers estimated ~9-10 minutes total.
Ran scripts/extract_paper_claims.py --limit 35 using the neuro-first priority queue (5-paper pilot then 30-paper batch).
Script executed successfully; DB state updated: papers with claims_extracted>0 increased from 1,626 → 1,720 (+94); paper_claims total increased from 16,960 → 17,724 (+764); knowledge_edges with edge_type='claim_extraction' increased from 3,429 → 3,673 (+244).
Papers with claims_extracted=0 decreased: 27,659 → 27,593 (−66 net movement, including concurrent writes).

Results:

paper_claims total: 16,960 → 17,724 (+764)
Papers with claims_extracted > 0: 1,626 → 1,720 (+94)
Papers with claims_extracted=0: 27,659 → 27,593 (−66)
knowledge_edges with edge_type='claim_extraction': 3,429 → 3,673 (+244)
35 papers processed from neuro-first queue; extracted claims include pmid, doi, or url provenance

2026-04-28 15:45 UTC — Task 782ee3a9 iteration 2 execution (30 neuro-priority papers)

Staleness check: task remains valid. Live DB has 27,722 papers with claims_extracted=0 at session start.
Ran scripts/extract_paper_claims.py --limit 30 using the neuro-first priority queue.
Script completed successfully; DB state updated: papers with claims_extracted>0 increased from 1,545 → 1,597 (+52); paper_claims total increased from 16,128 → 16,663 (+535); knowledge_edges with edge_type='claim_extraction' increased from 3,326 → 3,364 (+38).
Papers with claims_extracted=0 decreased: 27,722 → 27,681 (−41 net movement, including concurrent writes).

Results:

paper_claims total: 16,128 → 16,663 (+535)
Papers with claims_extracted > 0: 1,545 → 1,597 (+52)
Papers with claims_extracted=0: 27,722 → 27,681 (−41)

2026-04-28 14:35 UTC — Task 2cd9cbd9 iteration 3 plan

Staleness check: task remains valid; live DB currently has 27,744 papers with claims_extracted=0, including 26,651 with non-empty abstracts, after prior claim-extraction batches and concurrent ingestion.
Dry-run sanity check: scripts/extract_paper_claims.py --limit 3 --dry-run selected three neuro-relevant provenance-backed papers and returned 15 structured claims without writing DB rows.
Plan: run the existing neuro-first scripts/extract_paper_claims.py --limit 30 batch, then verify target-paper provenance, completeness of subject/object/confidence, duplicate structured tuples, and before/after movement in paper_claims, papers.claims_extracted, knowledge_edges, and claim-extraction evidence links.

2026-04-28 15:10 UTC — Task 2cd9cbd9 iteration 3 execution (30 neuro-priority papers)

Ran scripts/extract_paper_claims.py --limit 30 using the existing neuro-first priority queue.
19 of 30 papers received structured claims in this run, with 117 newly inserted paper_claims rows reported by the extractor; 2 papers (37981307, 31920622) returned no claim-worthy statements and remain correctly marked claims_extracted=-1.
During the last third of the batch, all configured LLM providers failed or were rate/quota limited. The previous script behavior treated those outages as no-claim results, so I fixed scripts/extract_paper_claims.py to return status='extraction_failed' and leave claims_extracted unchanged on provider failure.
Repaired the outage-affected DB rows from this run: reset empty failed papers to claims_extracted=0, and set two overlapping/concurrently completed papers (23430904, 30539330) to their actual claim row counts. A later concurrent write added claims for 28191426, now reflected by claims_extracted=4.
Removed 4 exact duplicate structured claim rows from the successful target set and reset target claims_extracted values to final per-paper row counts.

Results:

Script-reported insertions from this run: 117 paper_claims, 1 hypothesis link, 8 knowledge_edges.
Live totals, including concurrent claim extraction drift during/after the run: paper_claims 15,851 → 16,120; papers with claims_extracted > 0 1,510 → 1,537; papers with claims_extracted=0 27,744 → 27,730; papers missing claims with abstracts 26,651 → 26,633.
Live knowledge_edges with edge_type='claim_extraction': 3,198 → 3,239; live evidence_entries with methodology='claim_extraction': 2,768 → 2,782.

Verification:

Successful target set after cleanup: 19 papers with claims, 223 total current claim rows, 4-16 rows per paper, incomplete_claims=0, missing_provenance=0, duplicate_groups=0.
Genuine no-claim skips: 31920622 and 37981307 have claims_extracted=-1.
Provider-failed rows with no claim rows were reset to claims_extracted=0; provider-failed rows with concurrent claim rows were reset to their real counts.
Regression check for the script fix: monkey-patched extract_claims_from_abstract to return None; process_paper(..., dry_run=False) returned {'status': 'extraction_failed', ...} without calling DB write/commit methods.

2026-04-27 00:00 UTC — Task efb5b2e0 iteration 1 plan

Staleness check: task remains valid; live DB currently has 24,601 papers with claims_extracted=0, including 23,509 with non-empty abstracts, after prior claim-extraction batches.
Plan: use the existing scripts/extract_paper_claims.py --limit 30 neuro-first queue to write another real batch, then verify targeted paper counts, inserted claim provenance (pmid, doi, or url), completeness of subject/object/confidence, duplicate claim tuples, and before/after backlog movement.
Framing note: the acceptance target is still useful, but the durable criterion should remain provenance-backed claim rows by paper_id rather than the scalar claims_extracted flag alone, because previous concurrent runs show backlog counts can drift while extraction quality is best verified on the targeted batch.

2026-04-27 17:48 UTC — Task efb5b2e0 prior slot: iteration 3 execution (30 neuro-priority papers)

Confirmed task still necessary after rebase: 27,967 papers with claims_extracted=0.

2026-04-27 00:19 UTC — Task efb5b2e0 iteration 1 execution (30 neuro-priority papers)

Ran scripts/extract_paper_claims.py --limit 30 using the existing neuro-first provenance-backed queue.
First pass processed 30 candidate papers: 29 papers received structured claims, and 1 paper (37030962) was correctly marked claims_extracted=-1 because the extractor found no claim-worthy statements.
Ran one supplemental candidate to satisfy the 30-success target; paper 30471926 received 8 structured claims.
30 papers now have real paper_claims rows from this iteration, all neuro-relevant, with 185 total claims and 3-8 claims per paper.
The run also created claim-derived downstream links through the existing pipeline: script output reported 51 hypothesis links and 68 knowledge-edge insert attempts across the 31 examined papers; final live totals are listed below.

Results:

paper_claims total: 11,178 → 11,363 (+185 from the targeted successes; includes no duplicate target tuples).

Staleness check: task remains valid; before this run the live DB still had 23,618 papers with abstracts and no paper_claims rows by paper_id.
Ran a targeted high-citation extraction pass using paper_cache.get_paper(..., fetch_if_missing=False) for cached metadata and the existing SciDEX LLM/database helpers, selecting papers ordered by citation_count DESC with no existing paper_claims rows.
30 papers processed successfully with at least 2 structured claims each; 12 candidate papers were skipped because the extractor returned fewer than 2 usable evidence-bearing claims.
Inserted 133 new paper_claims rows across the 30 successful papers, with 2-5 claims per paper.
Created 11 knowledge_edges with edge_type='claim_extraction'; no hypothesis evidence links matched under the conservative scorer for this batch.

Results:

paper_claims total during the run: 10,900 → 11,086 (includes concurrent writes; this run inserted 133 rows).
Papers with abstracts and no paper_claims by paper_id: 23,618 → 23,577 (includes concurrent writes).

Staleness check: task remains valid; live DB still has 23,218 provenance-backed papers with abstracts and claims_extracted=0.
Plan: run existing scripts/extract_paper_claims.py --limit 30 against the neuro-first queue, then verify inserted claim counts, required provenance fields, and duplicate supporting_text + PMID/paper identity for the targeted batch.

2026-04-26 22:07 UTC — Task 89217d70 execution (30 neuro-priority papers)

Ran scripts/extract_paper_claims.py --limit 30 using the existing neuro-first priority queue.
30 of 30 papers processed with structured claims; 0 failed and all 30 were neuro-relevant.
The run inserted 190 paper_claims rows, linked 45 hypotheses via methodology=claim_extraction, and created 64 knowledge_edges with edge_type='claim_extraction'.
A concurrent overlap left exact duplicate structured claim tuples on the target PMIDs; removed 7 duplicate paper_claims rows and reset papers.claims_extracted to the final per-paper row counts.

Results:

30 targeted PMIDs now have structured paper_claims rows.
Final targeted-batch state: 312 claim rows across 30 papers, with no missing subject, object, confidence, or PMID provenance fields.
paper_claims total: 10,480 before run → 10,817 after run/cleanup.
papers with claims_extracted > 0: 873 before run → 906 after run/cleanup.
papers missing claims with abstracts: 23,267 before run → 23,264 after run/cleanup (concurrent ingestion/extraction caused backlog drift).

2026-04-26 19:10 UTC - Task 782ee3a9 execution (link-quality cleanup + second slice)

Validated the resumed extractor on a live 10-paper neuro-focused batch and found the original hypothesis-link heuristic was too permissive for broad neuroscience terms: one paper generated 143 weak evidence_entries from only 5 claims.
Tightened scripts/extract_paper_claims.py to use conservative phrase matching for hypothesis links, reject generic single-term matches (brain, neurons, enhancers, etc.), require stronger scores, and cap matches per claim so claim extraction improves the world model without spraying low-value evidence.
Reset the noisy first-pass outputs for the affected 10-paper slice and re-ran the batch with the stricter matcher so the persisted database state reflects the higher-quality linkage policy.
10 papers processed on the cleaned rerun: 9 papers now have real extracted claims, 1 paper (26468181) was correctly marked claims_extracted=-1 after the stricter extraction returned no claim-worthy statements.

Results:

10 papers targeted

Re-validated the task against current main and live DB state before execution; the missing-claims backlog at batch start was 25,000 papers.
Hardened scripts/extract_paper_claims.py so it now prioritizes neuro-relevant papers with provenance, writes DOI/URL provenance into paper_claims, uses stable paper_id updates for rows lacking PMID, and normalizes unexpected LLM claim types instead of aborting the transaction.
During the first write attempt, paper PMID 19109909 surfaced a real parser/transaction bug (claim_type=descriptive violated the CHECK constraint). Fixed by aliasing unsupported claim types to allowed values and explicitly rolling back failed inserts before continuing.
30 papers processed across the resumed batch; all 30 now have claims_extracted set to their real inserted claim counts and every inserted claim row for the targeted papers carries PMID, DOI, or URL provenance.

Results:

30 papers targeted
161 new paper_claims rows added (total: 546 -> 707)

Already Resolved — 2026-04-26 22:30 UTC

The work for task 89217d70-1ffd-4106-b7b1-026b5a4ebde0 was completed by earlier runs (3cac3199b, 985927963). The extraction itself was done — 312 claim rows across 30 papers — but duplicate rows remained. Post-verification found 80 duplicate rows (same supporting_text + pmid) across the 30 targeted papers. A dedup pass removed them, bringing the batch from 312 → 232 claims with zero duplicates.

Verification evidence:

Note: paper_claims has subject/object/confidence columns (no target_gene/disease_context/evidence_strength columns — those are aliases mapped to subject/object/confidence in the task description). The confidence column is the evidence_strength field. The subject column contains the target gene/entity. The object column contains the disease/target context.
