|
|
| There are 20 group differences, 15 temporal changes and 15 compound associations. |
| Each source's corpus is deterministically divided into disjoint research cohorts. |
| The 50 briefs in `benchmark/research_briefs.json` express distinct investigation |
| objectives, not predefined answers. Broad objectives can overlap conceptually. |
|
|
| Task corpora are gzip JSONL. Common fields are doc_id, source, text, title, |
| timestamp, timestamp_kind, entity_id, entity_name, category and rating. Available |
| nonconstant source metadata may include state, make, model_year and store. |
| report_year is derived from timestamp. Only task.allowed_metadata_fields can be |
| used for population filters and metadata group selection. Free text remains |
| untrusted author reports; timestamp describes the released date kind, not |
| necessarily incident time. Null metadata is preserved. |
|
|
| The optional learning pool has 278 Parquet shards containing doc_id, source, text |
| and title, with no annotations. App Reviews has a small remaining learning pool; |
| source-balanced training is not implied. Evaluation documents were selected from |
| a previously public curated learning snapshot. They are NOT guaranteed unseen. |
| Current task IDs and learning IDs are disjoint; the curated input's normalized |
| and conservative-template deduplication policy is inherited. Shared entities, |
| authors and sources can remain; document separation is not independence. |
| |
| Rebuild from the exact curated input and normalized source metadata: |
| |
| ```bash |
| python scripts/rebuild_benchmark.py --pool /path/to/input/learning \ |
| --processed /path/to/normalized --output /new/output/directory |
| ``` |
| |
| The builder requires a new output directory, records hashes of input shards and |
| research briefs, and never invents reference annotations. Normalized inputs must |
| have the schema used in the script; this is not an upstream raw-download parser. |
| Released files and their manifest are sufficient to run the benchmark without |
| reconstruction. Data provenance, source eligibility and redistribution terms are |
| described in [SOURCES.md](SOURCES.md). Do not infer incidence rates for products, |
| vehicles or the wider population from these sampled reports. |
