What is Intelligent Document Extraction (Key Value Pair Extraction)?

Enterprises handle vast volumes of semi-structured or unstructured documents daily. Traditional manual data entry is not only inefficient, error-prone, but also costly. Intelligent document extraction technology utilizes advanced techniques like OCR, NLP, and Machine Learning to automatically extract key information from documents, significantly improving processing efficiency, accuracy, and substantially reducing costs.

This article will delve into the core concepts of intelligent document extraction and its applications in businesses, showcasing its crucial role in optimizing document management and enhancing business processes.

Understanding Intelligent Document Extraction

Intelligent document extraction is the core of Intelligent Document Processing. It is an automated process that uses advanced technologies such as Artificial Intelligence (AI), Machine Learning (ML), and Natural Language Processing (NLP) to automatically identify, classify, and extract key information from unstructured or semi-structured documents. Compared to traditional methods, intelligent document extraction significantly improves extraction results, providing more accurate data for automated document workflows.
