PDF Document

PDF documents, a ubiquitous format for storing and sharing information, are the subject of intense research focused on improving information extraction and accessibility. Current efforts leverage deep learning models, including transformer networks and convolutional neural networks (CNNs), often combined with graph neural networks (GNNs) for structured data like tables, to automate tasks such as table extraction, text recognition (especially in challenging scripts), and question answering. These advancements are crucial for enhancing data management, enabling efficient analysis of large document collections, and improving accessibility for individuals with print impairments, impacting diverse fields from scientific research to business operations.
