Domain-oriented RAG Assessment (DoRA): Synthetic Benchmarking for RAG-based Question Answering on Defense Documents — Doan et al. (2026) (arXiv:2604.17943, 2026)
What this evaluates
Evaluates RAG-based question answering systems on defense-domain documents, measuring both retrieval effectiveness and end-to-end QA performance including task success, faithfulness, and generation quality.
Datasets
- DoRA — total 6500; splits: train (4635), eval (515)
Metrics
task-success(primary) — range: percent- Percentage of questions answered correctly according to reference answers or expert criteria.
faithfulness— range: [0, 1]- RAGEval-based metric measuring completeness, hallucination, and irrelevance of generated answers relative to retrieved evidence.
Tok. F1— range: [0, 1]- F1 score computed over token-level overlap between predicted and reference answers.
ROUGE-L— range: [0, 1]- Longest common subsequence recall/precision between predicted and reference answers.
BLEU— range: [0, 1]- Bilingual evaluation understudy score measuring n-gram precision with brevity penalty.
Input / output format
Input: Question q concatenated with retrieved evidence context ctx(E) (or gold context E for oracle evaluation).
Output: Generated answer a.
Scoring recipe
def compute_metrics(predictions, references, contexts):
token_f1 = [token_f1_score(p, r) for p, r in zip(predictions, references)]
rouge_l = [rouge_l_score(p, r) for p, r in zip(predictions, references)]
bleu = [bleu_score(p, r) for p, r in zip(predictions, references)]
task_success = [is_correct(p, r) for p, r in zip(predictions, references)]
faithfulness = [rag_faithfulness(p, c) for p, c in zip(predictions, contexts)]
return {
'token_f1': mean(token_f1),
'rouge_l': mean(rouge_l),
'bleu': mean(bleu),
'task_success': mean(task_success),
'faithfulness': mean(faithfulness)
}
Common pitfalls
- Retrieval error often dominates performance, masking model generation quality; fixed retriever settings should be reported.
- Faithfulness metrics (completeness, hallucination, irrelevance) require careful alignment with retrieved evidence, not just reference answers.
- Synthetic data generation may introduce intent mismatch or contamination if seed documents overlap with training corpora.
Evidence (verbatim from paper)
Results in Table 2 show that under a fixed retrieval setting, general-purpose LLMs cluster closely on both task-success and faithfulness, suggesting that retrieval and grounding constraints dominate performance in this private, defense-domain corpus.
