What are the four steps involved in Document Understanding?

The four steps involved in Document Understanding are indeed digitization, classification, extraction, and validation.

Digitization refers to the process of converting physical documents into a digital format, which is crucial as it enables further processing and analysis. This step is foundational, as the subsequent stages rely on having a digital representation of the document.

Classification involves determining the type of document being processed. This step is essential for applying the correct extraction techniques and recognizing the context of the information within the document.

Extraction is the stage where specific information and data are pulled from the classified document. This can involve recognizing key-value pairs, text, or other structured data that needs to be retrieved for further processing.

Validation is the final step, where the extracted data is verified for accuracy and completeness. This is important to ensure that the information can be trusted and used reliably in subsequent workflows or decision-making processes.

This sequence is integral to the Document Understanding framework, as it ensures that documents are appropriately processed, and the information extracted is accurate and actionable.
