Detecting Erroneously Recognized Handwritten Byzantine Text (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Handwritten text recognition (HTR) produces textual output that contains errors, which are much higher than recognised printed text. |
| Approach: | They investigate the properties of handwritten texts that lead post-correction systems to this adversarial behaviour in Byzantine Greek. |
| Outcome: | The proposed model achieves an average precision score of 95% in Byzantine Greek and 97% in modern and ancient Greek. |

| Challenge: | a large number of Greek papyri documents can only be dated tentatively or in approximation due to the lack of decisive evidence. |
| Approach: | a new study trains regression models to estimate Greek papyri's date using a dataset of 389 transcriptions . the authors propose a method to estimate the date of 159 Greek pamphlets, which are only the upper limit known . |
| Outcome: | a new study predicts a date for Greek papyri with an average MAE of 54 years and an MSE of 1.17 . the model outperforms image classifiers and other baselines for 159 manuscripts, with only the upper limit known . |
