# Optical Character Recognition on Ancient Greek Source: [Optical Character Recognition on Ancient Greek]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:39:06.411Z Evaluation of Optical Character Recognition performance on the Ancient Greek dataset, measured by Character Error Rate. 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 | Optical Character Recognition | | Dataset (including any stated split) | Ancient Greek | | Metric | Character Error Rate | | Unit | PERCENT | | Direction | Lower is better | | Results loaded | 15 of 15 | | 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 - [Character Error Rate](): Lower is better; unit: PERCENT. ## Recorded results | Method | Character Error Rate | Result date | Report paper | | --- | --- | --- | --- | | TrOCR (Base) | 2.7 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Base) | 3.8 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-Word (Small) | 4.3 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-T (Base) | 4.7 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-C (Base) | 4.9 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Base) | 5.1 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-C (Small) | 5.2 | Not recorded | 68fa74401e209131cea60891 | | Google Cloud Vision OCR | 6.5 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 12.9 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 13.8 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 15.7 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 20.4 | Not recorded | 68fa74401e209131cea60891 | | Tesseract OCR (Best) | 25.1 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 27.4 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 31.4 | Not recorded | 68fa74401e209131cea60891 | ### TrOCR (Base) Character Error Rate: 2.7.
