# Optical Character Recognition on Chronicle American LoCCA (eval) Source: [Optical Character Recognition on Chronicle American LoCCA (eval)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:39:06.395Z Evaluation of Optical Character Recognition performance on the Chronicle American LoCCA (eval) split, measured by Character Error Rate and processing speed (Lines/second). 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) | Chronicle American LoCCA (eval) | | Metric | Character Error Rate | | Unit | PERCENT | | Direction | Lower is better | | Results loaded | 18 of 18 | | 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. - [Lines per Second](): Higher is better; unit: SCALAR. ## Recorded results | Method | Character Error Rate | Result date | Report paper | | --- | --- | --- | --- | | Google Cloud Vision OCR | 0.5 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-Word (Small) | 1.5 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-T (Base) | 2.2 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Small) | 2.2 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-C (Base) | 2.3 | Not recorded | 68fa74401e209131cea60891 | | EffOCR-C (Small) | 2.8 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Small) | 3.1 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 3.6 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Base) | 3.9 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Base) | 7.5 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 10.3 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 10.4 | Not recorded | 68fa74401e209131cea60891 | | Tesseract OCR (Best) | 10.6 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 13.1 | Not recorded | 68fa74401e209131cea60891 | | EasyOCR CRNN | 17 | Not recorded | 68fa74401e209131cea60891 | | PaddleOCR SVTR | 30.4 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Small) | 77.3 | Not recorded | 68fa74401e209131cea60891 | | TrOCR (Base) | 80.9 | Not recorded | 68fa74401e209131cea60891 | ### Google Cloud Vision OCR Character Error Rate: 0.5.
