Unstructured data accounts for over 80% of all digital content, yet extracting actionable insights remains one of the most significant challenges for businesses, governments, and researchers. Unlike structured data stored in databases, unstructured data exists in forms such as documents, images, audio, and videos, making traditional processing inefficient.
Advanced AI-powered tools now play a crucial role in converting unstructured information into structured formats that improve searchability, classification, and automation. Selecting the right tool depends on various factors, including industry requirements, accuracy, scalability, and integration capabilities.
