Concept
Document processing
Résumé
Document processing is a field of research and a set of production processes aimed at making an analog document digital. Document processing does not simply aim to photograph or a document to obtain a , but also to make it digitally intelligible. This includes extracting the structure of the document or the layout and then the content, which can take the form of text or images. The process can involve traditional computer vision algorithms, convolutional neural networks or manual labor. The problems addressed are related to semantic segmentation, object detection, optical character recognition (OCR), handwritten text recognition (HTR) and, more broadly, transcription, whether automatic or not. The term can also include the phase of digitizing the document using a scanner and the phase of interpreting the document, for example using natural language processing (NLP) or technologies. It is applied in many industrial and scientific fields for the optimization of administrative processes, mail processing and the digitization of analog archives and historical documents.
Document processing was initially as is still to some extent a kind of production line work dealing with the treatment of documents, such as letters and parcels, in an aim of sorting, extracting or massively extracting data. This work could be performed in-house or through business process outsourcing. Document processing can indeed involve some kind of externalized manual labor, such as mechanical Turk.
As an example of manual document processing, as relatively recent as 2007, document processing for "millions of visa and citizenship applications" was about use of "approximately 1,000 contract workers" working to "manage mail room and data entry."
While document processing involved data entry via keyboard well before use of a computer mouse or a , a 1990 article in The New York Times regarding what it called the "paperless office" stated that "document processing begins with the scanner".
