Content Extraction

The process of separating meaningful content from the surrounding structural markup, navigation elements, and boilerplate text on a web page. For assistive technology users, content extraction is valuable because it allows them to focus on the substantive information on a page without having to navigate past repeated headers, menus, advertisements, and other non-content elements. Techniques include identifying and removing page templates, detecting updated versus static content, and presenting only the primary content area. Modern equivalents include reader mode in web browsers and the use of semantic HTML landmarks to identify main content regions.
