LLM-Based Research Extraction and Assessment
Automated extraction of claims, evidence, and methodology from research papers using Large Language Models, enabling systematic assessment of research transparency, reproducibility, and credibility.
Version: 3.0.1 | Schema: v2.6 | Workflow: v5.0.0 (8-pass, session-per-pass) Status: Extraction system complete, assessment framework pilot-tested, reproduction system v1.1 Target Domains: Fieldwork-based research (archaeology, ecology, ethnography, field geology, etc.) Manifest: See manifest.yaml for component versions
Overview
This repository contains tools and workflows for:
- Extraction (Complete): Systematically extract claims, evidence, implicit arguments, research designs, methods, and protocols from research papers
- Assessment (Pilot-tested): Evaluate research transparency, replicability, and credibility via research-approach classification, quality gating, and the repliCATS Seven Signals adapted for Humanities, Arts, and Social Sciences (HASS)
- Reproduction (v1.1): Docker-based reproduction of published computational analyses, with quantitative verification and adversarial review
The pipeline uses multi-pass workflows with Claude (Anthropic) to create structured JSON representations of research papers, enabling downstream analysis, credibility assessment, and reproduction attempts. All three systems were validated in a completed pilot study of five Journal of Archaeological Science papers (see studies/open-science-compliance/).
Quick Start
1. Install the Extraction Skill
# Install the research-assessor skill in Claude Code
# The skill is located at: .claude/skills/research-assessor/
See docs/research-assessor-guide/installation.md for detailed installation instructions.
2. Prepare Your Paper
# Extract text from PDF
python extraction-system/scripts/extract_pdf_text.py "your-paper.pdf"
# Output will be in: sources/processed-md/your-paper.md
See docs/user-guide/pdf-extraction.md for more details.
3. Run Extraction
Use the eight-pass workflow (Pass 0-7):
- Metadata Pass: Extract publication metadata and paper structure
- Claims/Evidence Pass 1: Liberal extraction of evidence, claims, implicit arguments
- Claims/Evidence Pass 2: Rationalisation and consolidation
- RDMAP Pass 1a: Liberal extraction of research designs, methods, protocols
- RDMAP Pass 1b: Implicit RDMAP extraction
- RDMAP Pass 2: Rationalisation and tier verification
- Infrastructure Pass: Extract PIDs, FAIR assessment, funding, permits
- Validation Pass: Structural integrity checks
See docs/user-guide/extraction-workflow.md for complete workflow guide.

Features
Extraction System (v2.6)
Six Object Types:
- Evidence - Observations, measurements, data points
- Claims - Interpretations, assertions, generalizations
- Implicit Arguments - Unstated assumptions, logical implications
- Research Designs - Strategic framing and rationale (WHY)
- Methods - Tactical approaches (WHAT was done)
- Protocols - Operational procedures (HOW specifically)
Multi-Pass Workflow (8 passes, 0-7):
- Pass 0: Metadata extraction
- Passes 1-2: Claims/Evidence (liberal extraction → rationalisation)
- Passes 3-5: RDMAP (liberal → implicit → rationalisation)
- Pass 6: Infrastructure (PIDs, FAIR, funding, permits)
- Pass 7: Validation ensuring structural integrity
Provenance Tracking:
- Every item linked to source text via verbatim quotes
- Location tracking (section, page, paragraph)
- Cross-references between all object types
- Complete consolidation metadata for traceability
Fieldwork-Specific:
- Respects abductive/inductive reasoning
- Tracks opportunistic decisions and adaptations
- Distinguishes planned vs. actual procedures
- Documents emergent discoveries
Assessment Framework (Pilot-tested, v1.0)
Three Pillars framework (Transparency → Credibility → Reproducibility) with the repliCATS Seven Signals adapted for HASS disciplines:
- Pass 8 — Classification: research approach (inductive/deductive/abductive) with HARKing detection
- Track A — Quality gating: extraction quality checks before assessment
- Pass 9 — Seven Signals in three clusters: Foundational Clarity (Comprehensibility, Transparency); Evidential Strength (Plausibility, Validity, Robustness, Generalisability); Reproducibility
Reliability evidence from a 25-run variability test (5 papers × 5 runs): 100% classification stability, 96% verdict stability, aggregate-score coefficients of variation 1.9–3.4% (see outputs/variability-test/).
See wiki/planning/credibility-implementation-plan-v2.0.md for the framework design.
Reproduction System (v1.1)
Docker-based reproduction of published computational analyses (R-based papers; Python/Julia extension points documented):
- Four-session workflow: planning (R-Plan), preparation (R-A), execution and verification (R-B), adversarial review (R-C, run in a fresh context)
- Paper-type classification (batch-ready/Dockerfile through interactive/proprietary) driving effort estimation
- Quantitative verification against every table, figure, and inline statistic, with a six-category discrepancy taxonomy including PAPER_ERROR (reproduction can surface errors in the published paper itself)
- Verdicts: SUCCESSFUL / PARTIAL / FAILED / BLOCKED
Pilot results (5 JAS papers): 4 SUCCESSFUL, 1 PARTIAL (sole cause: data inaccessibility), including exact reproduction of deterministic analyses and discovery of two calculation errors in a published table. See reproduction-system/ and the pilot findings report in studies/open-science-compliance/reports/.

Validation
The pipeline has been validated at three levels:
- Extraction corpus: 11 papers fully extracted (archaeology, ancient history, environmental science; see input/queue.yaml). A run comparison demonstrated the session-per-pass workflow captures 75% more claims and 100% more research designs than single-session extraction.
- Reliability: 25-run variability test (5 papers × 5 context-cleared runs) — extraction counts vary between runs, but assessments are stable: 100% classification stability, 96% verdict stability, aggregate-score CV 1.9–3.4%. Conclusion: a single run suffices for credibility assessment. See outputs/variability-test/.
- End-to-end pilot study: 5 Journal of Archaeological Science papers through the complete pipeline (extraction → assessment → FAIR scoring → Docker reproduction), 4 SUCCESSFUL / 1 PARTIAL reproductions. See studies/open-science-compliance/.
Earlier v2.5-era extraction-quality reports remain in reports/extraction-testing/.
