RegalFire Scientific Biology QA
RegalFire — AI Data Foundry
A mechanically normalized snapshot of public questions and answers from Biology Stack Exchange. No LLM-generated questions, answers, scientific claims or troubleshooting labels. RegalFire collected and packaged the data; source contributors retain authorship.
Contents
- 882 validated threads; 1,083 answers.
- 846 QA pairs, 882 ranking records and 3,650 external-reference edges.
- Thread splits: train 698, validation 92, test 92.
- 118 rejected threads are logged as IDs/URLs/reasons, without their bodies.
dataset.jsonl is the full canonical thread corpus. QA pairs are in scientific_qa.jsonl; candidate sets in answer_ranking.jsonl; mechanically extracted URLs and DOI-like identifiers in citation_graph.jsonl. Each derived record retains its canonical thread ID. Each view has corresponding split files under views/. Use the four explicit Hugging Face configurations; do not glob every JSONL file together.
Source and collection
Official Stack Exchange API 2.3, site=biology, using answered questions sorted by creation date, question/answer bodies, and paginated post revisions. Snapshot retrieval times and exact API URLs are retained in SOURCE_MANIFEST.json and per-post provenance. The target was 1,000 answered questions, with no requirement for an accepted answer. Quota and backoff were honored, including a documented initial throttle response and conservative retry. API snapshots can change over time.
License and attribution
All published current question and answer bodies in this release explicitly reported CC BY-SA 4.0 in the API. This is an observed property of this selected snapshot, not an assumption about Stack Exchange history. Historical policy includes CC BY-SA 2.5 and 3.0; per-revision licenses returned by the API are preserved. Missing or unsupported current-post license fields trigger rejection. See official licensing and SOURCE_LICENSE_AUDIT.json.
Retain attribution when redistributing or displaying records: question title, Biology Stack Exchange source, contributor display names, available profile links, original question/answer URLs, applicable license links, revision contributors, and a description of transformations. Deleted or unavailable profiles are explicitly represented by null URLs; do not invent identities. The canonical thread record contains the full revision attribution for each post. If exporting a derived view alone, carry its referenced canonical attribution along with it.
Example citation format: “[Question title](original question URL), by [question author](profile URL), Biology Stack Exchange; answer by [answer author](profile URL), [original answer](answer URL), CC BY-SA 4.0; collected at the recorded timestamp; mechanically converted from HTML and packaged by RegalFire.”
CC BY-SA 4.0 permits sharing and adaptation, including commercial use, subject to attribution, ShareAlike and no additional restrictions. RegalFire packaging does not replace source licenses. Source HTML can reference third-party quotations/images with separate rights; no external image, paper or other asset is downloaded or repackaged. Explicit conflicting rights notices are rejected. A source post license is not a guarantee about every embedded third-party element.
Transformations and selection
Original API HTML is retained. Mechanical HTML parsing decodes entities, preserves source text, TeX strings, gene/protein identifiers, chemical/scientific notation, code indentation and paragraph boundaries, and adds literal hyperlink destinations and image-reference markers to text. Superscripts/subscripts are flattened in text; original markup remains in HTML. No equation rendering, OCR, translation or paraphrasing is performed. No scripts/styles are executed. Treat retained HTML and external links as untrusted content; sanitize before rendering.
Threads are excluded for empty/short content, negative question scores, closed/migrated state, incomplete answers/accepted-status snapshots, absent licenses, incomplete revision attribution, explicit conflicting rights notices, Unicode replacement characters, exact duplicate question text, or the patient-specific heuristic. Community scores are selection signals, not truth labels. QA chooses the accepted answer when present; otherwise the highest-scoring answer with score at least 1, breaking ties by lowest answer ID. No accepted answer is fabricated. Ranking retains all collected candidates, community scores and accepted status. Citation edges denote references only: DOI patterns, URLs and their correctness are not scientifically verified.
Troubleshooting extraction is omitted because no reliable deterministic problem/attempted-method/solution rule was established.
Validation and leakage
The independent validator does not import the normalizer. It checks nested schema, IDs, source equality, answer relationships, accepted status, authors and revision contributors, per-post licenses, UTF-8, raw SHA-256/HTTP provenance, scientific-text preservation, derived selection, citation coverage, statistics and split content. Controlled corruption tests cover relationships, licenses, attribution, provenance hashes, invented text, accepted status, duplicates, revision removal, sensitivity flags and citation removal.
Exact normalized title/body groups and exhaustive word-trigram Jaccard similarity >= 0.80 are grouped before deterministic SHA-256-based 80/10/10 bucket assignment. The realized sizes differ from exact percentages. This lexical grouping does not establish absence of semantic paraphrases, repeated answers or overlap with other public training corpora. Already-public Stack Exchange content is not a contamination-resistant private benchmark.
Intended uses and limitations
Research in retrieval, provenance-aware QA, answer ranking, attribution and reference extraction. No expert scientific correctness review, citation verification, medical validation or model performance evaluation has been performed. Most ranking records have only one answer; use multi-answer records when testing comparative ranking. Selection excludes low-scoring questions and therefore introduces community/popularity bias. The snapshot covers English Biology Stack Exchange, not all scientific disciplines.
No medical advice
128 retained threads have a medical-sensitivity flag. First-person patient-specific discussions are excluded by an English keyword heuristic. The screen can miss sensitive content and produce false positives. Forum discussion is not medical advice and must not be treated as diagnosis, treatment recommendations or a clinical reference.
Reproduce and verify
Native Windows Python is supported. The local pipeline lives under scientific_forums/codex. Run collector_stackexchange.py --target 1000, audit_raw.py, make_schema.py, normalize_stackexchange.py, then validate_scientific_forum_dataset.py. Collection stores immutable response bodies and separate HTTP metadata, plus a checkpoint. Source payloads remain in the local capture archive; they are not bundled publicly because they include excluded content. Full source validation requires that archive and the audit. A fresh live API collection can differ from this snapshot.
Use python pipeline/validate_scientific_forum_dataset.py --release <downloaded-release> --source-root <scientific_forums-root> with the original local archive. MANIFEST.json lists SHA-256 and byte sizes for every release file except itself, which cannot contain its own hash. Byte-identical re-normalization and no-request collector resume are documented in REPRODUCTION_REPORT.json.
Custom / Private Dataset Work
RegalFire builds custom AI datasets, evaluation sets and reproducible data pipelines for research and production systems.
