What is Document Processing?
Document processing refers to analyzing physical documents, PDFs, and images, extracting relevant information, and converting them into machine-readable formats for storage, retrieval, and integration purposes.
Traditionally, document processing referred to the manual method where data operators scanned pages manually to locate the vital data. However, advancements in technologies streamlined document processing and automated data extraction tasks.
How Does Document Processing Work?
Document processing ai involves different methods such as neural networks, computer vision algorithms, and manual labor. The analog to digital data conversion process involves the steps below that make document processing effective.
1. Categorization and extraction of structure and layout
Document processing solutions are based on a specific set of rules. Once these predefined rules are defined, the team implements structure and layout extraction.
2. Document information extraction
OCR or Optical Character Recognition, involves the scanning of documents from the manual documents and their transformation to data. HTR, or Handwritten Text Recognition is another intelligent character recognition technology used to recognize the standard text as well as different styles and fonts of your handwriting. This technology can be used in image-to-text converters to automatically extract text from image and documents.
3. Document error detection and correction
The OCR technology is sensitive to errors, hence requiring a manual review post the data extraction. If a document cannot be processed or errors are recognized, it can be further flagged for a human review, and you can fix the errors with a manual entry.
4. Document and data storage
The processed document is stored in an ideal format that lets it integrate with the existing business applications.
The Role of AI and Machine Learning in Document Processing
1. How AI Transforms Data Capture and Analysis?
