Evaluation of Authorship Verification performance across the combined test sets of PAN Average datasets spanning 2013, 2014, and 2015, reporting language-specific and overall ROC-AUC 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 | Authorship Verification |
| Dataset (including any stated split) | PAN Average 2013-2015 (test) |
| Metric | Greek Avg ROC-AUC |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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.
