================================================

*** GOAL ***

Improve/denoi
se OCR-ed texts, based on an a original corpus of OCRed documents composed of 12M characters (2.1M tokens) aligned with their corresponding Gold Standard, with an equal share of English- and French-written materials. You can participate in English, French, or both. Given the noisy OCR of printed text, the participants are invited to participate in the two following independent subtasks : 1) DETECTION and 2) CORRECTION. The participant are encouraged to compute separate scores for the English- and the French-written parts of the collection, allowing for the evaluation of language-specific approaches.



- TASK 1)
Detection of OCR errors: given the raw OCR-ed text, the participants are asked to provide the position and the length of the suspected errors.

- TASK 2) Correction of OCR errors: given the OCR errors in their context, the participants are asked to provide, for each error, either a) only their one correction or b) a ranked list of candidates for correction. Providing multiple candidates enables the indirect evaluation of semi-automated techniques, with a human in the loop.
