Evaluation of Knowledge Base Question Answering performance on the CFQ dataset, reporting metrics related to MCD1, MCD2, and MCD3 subsets.

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 | Knowledge Base Question Answering |
| Dataset (including any stated split) | CFQ (MCD1, MCD2, MCD3) |
| Metric | MCD1 Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| 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

- [MCD1 Accuracy](<https://www.sota2.com/research/sota/knowledge-base-question-answering-on-cfq-mcd1-mcd2-mcd3.md?metric=MCD1%20Accuracy>): Higher is better; unit: PERCENT.

- [MCD2 Accuracy](<https://www.sota2.com/research/sota/knowledge-base-question-answering-on-cfq-mcd1-mcd2-mcd3.md?metric=MCD2%20Accuracy>): Higher is better; unit: PERCENT.

- [MCD3 Accuracy](<https://www.sota2.com/research/sota/knowledge-base-question-answering-on-cfq-mcd1-mcd2-mcd3.md?metric=MCD3%20Accuracy>): Higher is better; unit: PERCENT.

- [Mean Accuracy (MCD)](<https://www.sota2.com/research/sota/knowledge-base-question-answering-on-cfq-mcd1-mcd2-mcd3.md?metric=Mean%20Accuracy%20(MCD)>): Higher is better; unit: PERCENT.
