QO-Bench
Official benchmark data for QO-Bench: Diagnosing Query-Operator-Preserving Retrieval over Typed Event Tuples, accepted to Findings of the Association for Computational Linguistics: EMNLP 2026 (arXiv:2606.04646).
QO-Bench evaluates query-operator question answering (QO-QA): natural-language questions that specify database-style operators (filter, join, intersection, count, group, order) over corporate-event records latent in a 22,984-article financial-news corpus (NASDAQ subset of FNSPID, 2010–2023). Gold answers are computed deterministically from 614 typed event tuples keyed by public identifiers and attested by a unanimous 3-of-3 judge consensus — no LLM-as-judge at scoring time.
Code, baselines (RAG, ReAct RAG, GraphRAG, IE→SQL, LC-oracle), per-paradigm predictions, and the official scorer live in the GitHub repository: https://github.com/ZHANG-MENGAO/qo-bench.
Files
| File | Description |

questions.jsonl.gz |
The 785 evaluation questions with typed gold answers |
templates_config.json |
18-template scoring configuration (paper A/B template IDs) |

Record schema
One JSON object per line in questions.jsonl.gz:
| Field | Description |
|---|---|
qid |
Unique question id |
id, cap, sub_axis |
Template id (A.1.1–B.4.4), capability class (A/B), sub-axis |
params |
Typed template parameters (event type E, time window, role, thresholds, …) |
nl_question |
The rendered natural-language question |
gt |
Gold answer: a list of typed event tuples {firm_ticker, event_type, anchor_date, role, counterparty_ticker, golden_chunks}; golden_chunks carries the 3-of-3-attested provenance articles (URL, title, date, cited sentence) |
gt_size |
Number of gold tuples |
Evaluation
Score predictions with the official scorer (strict and tolerant ±7-day matching, the paper's main metric):
python -m qobench.eval.eval_tolerant \
--questions questions.jsonl.gz \
--predictions predictions.jsonl \
--config templates_config.json \
--output results.json

License and provenance
Released under CC-BY-NC-4.0. The dataset contains no S&P Capital IQ content: every ground-truth event is a public-identifier tuple (stock ticker / SEC CIK / LEI, event type anchored to public disclosure classes, anchor date, role, counterparty) with provenance into the public FNSPID news corpus. Reproducing every experiment in the paper requires no proprietary data.
