BVA Answer-or-Abstain QA
Question–answer pairs over public U.S. Board of Veterans' Appeals (BVA) decisions, labeled for whether the document actually supports an answer. Built to train and evaluate a model's ability to answer when grounded and abstain when the answer is not in the document — i.e., to say "not in the document" instead of hallucinating.
- Rows: 3,014 (open sample)
- Answerable: 2,032 (67%)
- Unanswerable (abstain): 982 (33%)
- Scale: this is a 3,000-row sample of a 31,000+ row set; full sets and custom corpora are available separately.
Why this exists
Most "abstention" datasets fabricate their unanswerable questions. Here, every unanswerable question is verified absent from a real source document — the answer is genuinely not present — so a model learns honest refusal grounded in real text, not a synthetic pattern.
Format
One JSON object per line (uncertainty.jsonl):
| Field | Description |
|---|---|
id |
Unique row id |
source_url |
Link to the original public decision (independent verification) |
source |
Source domain tag (bva) |
question |
The question |
context |
Document text when included (else null — use source_url) |
answerable |
true if the document supports an answer, else false |
answer |
The grounded answer when answerable; otherwise "The document does not state this." |
Examples
{"id":"…","source_url":"https://www.va.gov/…","source":"bva",
"question":"What outcome did the adjudicator reach on the issue: ...?",
"answerable":true,"answer":"denied"}
{"id":"…","source_url":"https://www.va.gov/…","source":"bva",
"question":"What evidence does the decision discuss for the issue: ...?",
"answerable":false,"answer":"The document does not state this."}
Grounding
Every unanswerable question is verified absent from its source document. Each row
links to the original decision via source_url for independent checking.
