Voting & Processing Service
Users can vote for the image digitization or text recognition (OCR) processing of specific sources. Your votes help prioritize our efforts, ensuring that the most in-demand data is made available in digital format as soon as possible.
Image Digitization is the process of converting analog visual information, such as photographs, artworks, or printed materials, into a digital format.
Text Recognition (OCR, Optical Character Recognition) is the process of converting different types of documents, such as scanned paper documents, PDFs, or images captured by a digital camera, into editable and searchable full-text data. In most cases, a standard OCR process is not sufficient for the quality of research data, so the OCR needs to be fine-tuned to the source material in a pre-process. For more information about a sufficient OCR process, use your OCR Recommender.
As a registered user, votes can be submitted for image digitization or OCR for each source. If the source has already been digitised and/or transcribed, but in insufficient quality, please specify this in the comment field. You can express your own preference as to how important voting for this source is for you by giving it 1-5 stars.
With the help of the comment field, the votes can be further specified and/or the reasons for the vote can be recorded.
