Field Atlas reader training data
9,497 training examples and a 400-item held-out set for teaching a small model to answer from given passages with citations, to say "The saved sources don't say." when they do not answer, and to name the missing part when they only half answer. Built for poidh bounty #45 and used to train SAFWAAN/fieldatlas-reader-qwen3.5-2b.
Files
| File | Rows | What it is |
|---|---|---|
train_items.jsonl |
9,497 | Full training items in the benchmark's schema: id, category, question, passages (n, title, text, chunkId, source), answerable (yes / partial / no), reference (the target answer), keyFacts, cites, pack |
train_chat.jsonl |
9,497 | The same items as chat messages (system, user, assistant), ready for SFT. The system and user texts are produced by reader_bench.SYSTEM and reader_bench.prompt() from the Field Atlas repo, so they are identical to what the app sends |
heldout.jsonl |
400 | Same schema as train_items.jsonl; scored with reader_bench.py score. Frozen before any training; never used for model selection |
Label mix (training): about 41 % fully answerable, 33 % partly answerable, 26 % not answerable. Categories: fact, explain, travel, compare, biology, synthesis, crypto, health, first aid, insufficient-information. Passages per item: 1–8, mostly 4–7, like the benchmark.
How each example was made
The pipeline (gen.py, fetch.py, run.sh in the model repo) mirrors how the benchmark's own items were built:
- Seed passage drawn from the Field Atlas knowledge packs the app actually installs (
fetch.pydownloads the pinned.fapackfiles from 0x94t3z/fieldatlas-knowledge and 0x94t3z/fieldatlas-encyclopedia). Encyclopedia and travel seeds come from Wikipedia's "vital articles" list in the repo, so questions are about well-known topics; first-aid seeds from a fixed list of first-aid topics. - Question written by the teacher model in one of several registers (casual phone typing, full sentence, two-part question, keyword search…), targeted at a label: fully answerable, partly answerable (one part not in the passage) or not answerable (same topic, detail not covered).
- Passages retrieved by a replica of the app's own search (
tools/evaluation/e2e_test.pyfrom the repo: FTS5 ranking + planner keywords), mostly from the question's own collection plus 0–3 off-topic passages from another collection, with the seed passage at a random rank. This reproduces the noisy passage sets the model sees on the phone. - Answer, label and key facts written by the teacher under the benchmark's exact system prompt, with explicit rules: cite every sentence, copy numbers verbatim, no outside knowledge, exact refusal wording, gap sentence last for partial answers, no first-aid steps the passages do not give.
- Two filters. (a) The benchmark's own scorer (
reader_bench.score_item) plus style checks: every sentence cited, no citation to a missing passage, no number outside the passages, key facts present in cited passages, exact refusal phrasing. (b) An independent checker from a different model family reads the passages and the answer and fails anything unsupported, mislabelled, incomplete, unsafe or off-topic. About 70 % of generated answers pass both.
Teacher: deepseek-flash (DeepSeek API; its terms allow using outputs to train other models). Checker: openai/gpt-oss-120b (Apache-2.0), used for pass/fail only; none of its text is in the data. No model whose terms forbid training on its outputs was used anywhere.
Exclusions, so the benchmark stays clean
- No passage from any dev-set article (title or source URL) appears in any training item.
- No question is within a Jaccard similarity of 0.5 of any of the ~4,700 questions found anywhere under
docs/fieldtest/in the Field Atlas repo at commit296b2fc— the sealed test set is built from those field tests. - The held-out set was split off once and frozen; later data top-ups could not move items between splits.
Licences
- Questions, answers, labels and key facts (our annotations): CC BY-SA 4.0.
- Passage texts are reproduced from the Field Atlas knowledge packs and keep their original licences, with attribution in each pack's
ATTRIBUTIONfile: Wikipedia and Wikivoyage text CC BY-SA 4.0; Ethereum EIPs/ERCs and consensus specs CC0; OpenStreetMap-derived text ODbL; biology passages are PubMed Central open-access articles under their individual licences (mostly CC BY, some CC BY-NC — check thesourceURL of an item before commercial reuse). - Every item carries its passages'
sourceURLs, so attribution is per item.
Intended use and limits
Made for training and evaluating small grounded readers that must cite and abstain. English only. The reference answers are machine-written and machine-checked, not human-verified; the two-filter pass rate suggests they are accurate but not perfect. Key facts in heldout.jsonl were copied verbatim from the reference answers without alternative wordings, so they score stricter than the maintainer's dev set (see fairscore.py in the model repo for a wording-tolerant comparison).
