Form data extraction has become crucial in today's data-driven world, where forms are everywhere. Intelligent document processing (IDP) leverages OCR, AI, and ML to automate form processing, making data extraction faster and more accurate than traditional methods. IDP can handle both structured and unstructured documents, adapt to various layouts, and continuously improve its performance through machine learning. Advanced techniques like Graph CNNs, LayoutLM, and Form2Seq offer improved accuracy in extracting information from forms with complex structures or handwritten entries. To implement these advanced methods, consider best practices such as data preparation, pre-processing, model selection, fine-tuning, post-processing, scalability, and continuous improvement. Nanonets' AI-based OCR system is a powerful solution that tackles common pain points in OCR technology, offering superior accuracy, adaptability to diverse document types, seamless integration with workflows, enhanced security, and growth capabilities. By adopting these advanced methods and solutions, businesses can transform their document processing experiences, increase efficiency, and save valuable time.
