Multi-Source Search (imaging literature + datasets)
Find and verify imaging-research papers and datasets across the right sources, merge without double-counting, and hand clean candidates to citation/export.
Core stance
- Right source first. PubMed for biomedical recall (+ MeSH); arXiv for imaging-AI methods and preprints; Crossref for DOI/cross-disciplinary metadata. Dataset registries for data.
- Verify identifiers (DOI/PMID/arXiv) before citing; expose failed/missing metadata.
- Deduplicate by DOI → PMID → arXiv ID → normalized title; don't count duplicates as independent evidence.
- Recall vs precision — for systematic/DTA reviews use MeSH + structured strategy and log it (PRISMA-DTA reproducibility); for quick lookups, precision.
- No fabrication — never invent volume/issue/pages/DOI/dataset accession.
When to use
- "Find recent papers on [imaging-AI topic]." / "Systematic search for a DTA meta-analysis."
- "Is there a public dataset for [task/organ/modality]?"
- "Verify these DOIs/PMIDs." / "Expand my query with MeSH terms."
- "Build a literature map / gap matrix / local paper RAG plan for this manuscript."
When to open extra files
| File | Open when |
|---|---|
| references/source-tiers.md | Which source to query first; fallback order; MeSH; recall vs precision; dedup keys |
| references/dataset-sources.md | Finding imaging + omics datasets (TCIA, GEO, cBioPortal, OpenNeuro, Grand Challenge, MSD) |
| references/literature-survey-workflow.md | The user needs field mapping, Introduction support, reviewer-defense literature, dataset scouting, or a manuscript-level literature synthesis rather than a quick lookup |
Workflow
- For survey-level or local-corpus work, open
literature-survey-workflow.mdand choose the mode: Intent / Triage / Deepen / Synthesize / Expand. Use its local paper/RAG ladder before expensive synthesis when a paper database is available. - Classify the need — papers vs datasets; quick lookup vs systematic recall.
- Build the query — concepts (translate Chinese → English scientific terms); for PubMed add MeSH; record the strategy for systematic searches.
- Search the right sources (source-tiers.md), per-source limits; for data use dataset-sources.md.
- Merge & dedup across sources by identifier/title.
- Verify key identifiers; flag unresolved.
- Return a ranked, deduplicated candidate list (+ a logged strategy for systematic
searches). Hand export to
radiology-citation.
MCP/tooling note
Works in prompt mode (built-in search tools, following these rules) or with an academic-search
MCP exposing search_papers / get_paper_by_id / get_citation / lookup_mesh. Set a
contact email for PubMed E-utilities; optionally NCBI_API_KEY for higher rate limits.
(Restricted/blocked domains: do not attempt to bypass — report inaccessibility.)
Output contract
Strategy— sources queried, query strings/MeSH, limits, dates (full log for systematic searches).Candidates— deduplicated:Title | Authors | Year | Venue | DOI/PMID/arXiv | Verified?.Datasets(if requested) —Name | Source | Modality/omics | n | Access | Accession.Survey artifacts(if survey-level work) — corpus log, paper-note/gap-matrix summary, local/RAG index status when relevant, exemplar craft notes, reviewer-objection candidates, and claim-ready citation roles.Unresolved/Incomplete— failed lookups and missing metadata.
Handoffs
Citation grading/export → radiology-citation; dataset access/governance & availability
statements → radiology-data; systematic-review reporting → radiology-reporting (PRISMA-DTA);
full bilingual read of a key retrieved paper → radiology-reader.
