Information extraction, utilizing techniques like Optical Character Recognition (OCR), Named Entity Recognition (NER), and Deep Learning, is a process to convert unstructured data into structured formats, significantly reducing manual labor and errors for businesses. It involves tokenization, parts of speech tagging, dependency graphs, and the use of models such as spaCy for NER, enhancing data processing capabilities across various sectors. The process typically includes collecting data from diverse sources, processing it using OCR for non-digital documents, and applying appropriate models, such as BERT, for extracting relevant information. Evaluation of these models through metrics such as accuracy, precision, and recall is crucial before deployment. Applications of information extraction span multiple industries, including finance, healthcare, and legal sectors, enabling tasks like invoice automation, patient record management, and compliance checks. Integrating pre-trained models, like those offered by Nanonets, can further streamline these processes, allowing seamless deployment in production environments.
