Which method is considered the slowest when reading text?

The method that is considered the slowest when reading text is optical character recognition (OCR). This technology involves scanning and interpreting text from images or documents, which requires processing power to analyze visual data, recognize characters, and convert them into machine-readable text. Since OCR involves complex image processing algorithms, it can be time-consuming compared to other methods that operate directly on digital text content.

In contrast, methods like data scraping, full text extraction, and native text extraction work with structured or unstructured data that is already in a digital format. These methods typically retrieve text more efficiently because they do not need to analyze images or visual representations of text, allowing for quicker data access and processing. This efficiency contributes to a significant disparity in speed when compared to the image-based recognition inherent to OCR.
