Welcome to the ERA AI Meta-Analysis Repository, part of the Sustainable Farming Program. This project advances evidence synthesis and meta-analysis by automating the repetitive while keeping the complex scientific questions squarely in the hands of domain experts.
At a high level, the workflow systematizes literature discovery and triage using OpenAlex (with optional benchmarking against Web of Science), then applies AI-assisted screening, tagging, and keyword extraction to rapidly structure information for downstream analysis. The goal is not to replace scientific judgment, but to amplify it, freeing scientists to interrogate mechanisms, uncertainty, and context, while the pipeline handles query engineering, data wrangling, and transparent reporting.
The repository ships with ready-to-knit reports and configurable YAML policies so methods are reproducible, auditable, and adaptable across agricultural and climate research topics.
This repository aims to:
- Provide a reproducible, R-based pipeline for literature discovery and triage across multiple scholarly sources (e.g., OpenAlex, and optionally Web of Science/Scopus/others).
- Enable AI‑assisted screening, tagging, and structured data extraction to accelerate evidence mapping and meta‑analysis.
- Support benchmarking and quality assessment (e.g., inter‑annotator checks, hold‑out labels, and cross‑source comparisons) with simple, transparent metrics.
- Produce shareable, versioned HTML reports and machine‑readable outputs (e.g., Parquet/JSONL) for transparency and collaboration.

# restore dependencies (recommended)
R -q -e "install.packages('renv', repos='https://cloud.r-project.org'); renv::restore()"
# if renv.lock does not exist yet:
# R -q -e "install.packages('renv'); renv::init(); renv::snapshot()"Note: OpenAlex is public—no API key needed. If you use an LLM for screening/tagging, add keys to ~/.Renviron (see Configuration).
Create or edit ~/.Renviron (user-level) or a project .Renviron:
