Evaluation of model performance on the PathQuestion (PQ) 2H 1.0 dataset for multi-hop knowledge-based question answering, typically measured using Accuracy.

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 | Multi-hop Knowledge-based Question Answering |
| Dataset (including any stated split) | PathQuestion (PQ) 2H 1.0 |
| Metric | Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 10 of 10 |
| 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

- [Accuracy](<https://www.sota2.com/research/sota/multi-hop-knowledge-based-question-answering-on-pathquestion-pq-2h-1-0.md?metric=Accuracy>): Higher is better; unit: PERCENT.
