**TLDR:** A task that matches field names with their corresponding values in a document to create structured data.

<p>Key-value extraction directly determines the production value of form and document automation systems. Fields such as "Name," "Date," or "Total Amount" must be correctly linked with their corresponding contents. This task requires not only OCR but also layout understanding, contextual proximity, and sometimes semantic relation modeling. It sits at the heart of invoice, application-form, and enterprise document automation.</p>
