# Open-domain Question Answering on Natural Questions abundant Source: [Open-domain Question Answering on Natural Questions abundant]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:41:42.377Z Evaluation of model performance on the 'abundant' subset of the Natural Questions dataset for Open-domain Question Answering, typically measured using Exact Match and F1 scores. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Open-domain Question Answering | | Dataset (including any stated split) | Natural Questions abundant | | Metric | EM & F1 Score | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 6 of 6 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [EM & F1 Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | EM & F1 Score | Result date | Report paper | | --- | --- | --- | --- | | Thrust | 37 | Not recorded | 68fa777a1e209131cea73718 | | Thrust | 35.7 | Not recorded | 68fa777a1e209131cea73718 | | Thrust | 33.9 | Not recorded | 68fa777a1e209131cea73718 | | Default | 29.7 | Not recorded | 68fa777a1e209131cea73718 | | Default | 29.4 | Not recorded | 68fa777a1e209131cea73718 | | Default | 28.2 | Not recorded | 68fa777a1e209131cea73718 | ### Thrust EM & F1 Score: 37.
