Biophoton / Ultra-Weak Photon Emission Field Map An open, versioned map of the biophoton / UPE research field: 18,355 works and 39,312 authors, seeded from Michal Cifra's library and enriched via OpenAlex, clustered into sub-fields and scored for openness. Version 1.0.0 . Snapshot 2026-07 (OpenAlex) . License: CC0 1.0 (public domain). DOI: https://doi.org/10.5281/zenodo.21466492 (cite all versions). This release: https://doi.org/10.5281/zenodo.21466493 What is in here - data/fieldmap.sqlite and parquet/CSV exports: works, authors, institutions, authorships, topics, citation and co-authorship edges, sub-field communities.- data/paperindex.sqlite: every work ranked by a composite importance score, with a full-text search index (contentless FTS5) and abstracts in inverted-index form. data/paperindexranked.csv is the compact ranked list.- data/researchers.csv: the ranked researcher tables (public identifiers only).- graphs/.graphml.gz: co-authorship, coupling, co-citation, topic graphs for Gephi (gzip-compressed; gunzip before opening).- tools/fieldmapreport.html, tools/papersearch.html: self-contained interactive views. Open in any browser.- docs/: methods, the state-of-field report, and OSF PDFs. Abstracts Abstracts are distributed as an inverted index (word to positions), mirroring OpenAlex. The tools reconstruct reading order in your browser. No ordered abstract prose is stored in this release. Privacy This release contains public identifiers only (names, ORCID, ROR institutions). Corresponding-author email addresses collected during the project are held privately by OSF and are not part of this release.

Zenodo. https://doi.org/10.5281/zenodo.21466493 To cite the resource across all versions, use the concept DOI https://doi.org/10.5281/zenodo.21466492 (it resolves to the latest release). See `CITATION.cff` for machine-readable metadata. Citation is requested but, under CC0, not required. Provenance and reproducibility Derived from OpenAlex (CC0). The build pipeline is idempotent and cached; each release pins its snapshot date. Known limitations: some author records are split by OpenAlex disambiguation (a few are merged here; others are flagged in data/authorsplitsflagged.json), and a small amount of grey literature is not in OpenAlex (data/seedunmatched.csv). Corrections are welcome.
