EfficientOCR: An Extensible, Open-Source Package for Efficiently Digitizing World Knowledge (2023.emnlp-demo)
Copied to clipboard
| Challenge: | Existing OCR engines fail to provide accurate, cost-effective and sample-efficient character recognition for public domain documents. |
| Approach: | EffOCR is an open-source optical character recognition package that is accurate, cheap to deploy and sample efficient to customize to novel collections, languages, and character sets. |
| Outcome: | EffOCR model trains character retrieval problem and scales to novel collections, languages, and character sets. |
Efficient OCR for Building a Diverse Digital History (2024.acl-long)
Copied to clipboard
| Challenge: | Current optical character recognition (OCR) systems are poorly extensible to low-resource document collections, as learning a language-vision model requires extensive labeled sequences and compute. |
| Approach: | They propose to model optical character recognition as a character level image retrieval problem using a contrastively trained vision encoder. |
| Outcome: | The proposed model is more sample efficient and extensible than existing architectures, enabling accurate OCR in settings where existing solutions fail. |
