OCR (optical character recognition), the technology of scanning the image of a word and recognizing it digitally as that word, is widely used by data entry companies. It is easy to capture data from paper using this technology and therefore, in many cases, OCR is considered a better option than manual data entry.
However, OCR is not perfect. Though it makes data entry easy, errors can occur as sometimes, the OCR software may fail to recognize words correctly. This can happen when image quality is poor. It can prove extremely expensive to correct OCR errors.
The solution lies in OCR cleanup. A reliable data entry company would have a sound cleanup system in place. The cleanup process is performed manually by correcting the errors made by the OCR software in the character recognition step. The original documents are meticulously compared with those from the scanned files. Every misread character and word is correctly replaced in text, footnotes, tables, graphs, and other parts of the document. Carefully executed OCR cleanup ensures ASCII or Unicode versions of documents with an accuracy level of up to 99.99%.
OCR cleanup is crucial in the case of documents for which a high level of accuracy is mandatory. This includes medical forms, insurance forms, banking forms, survey forms, books, magazines and directories. So if business involves dealing with any of these categories, take care to choose a data entry service provider that has efficient OCR cleanup services on its menu.
