Semantic Model

An abstract representation of a web page that captures the meaning and relationships of its content, rather than its raw HTML structure. Unlike the Document Object Model (DOM), which represents syntactic elements, a semantic model groups related elements into meaningful entities such as forms, search results, navigation menus, and product listings based on their purpose and visual/logical relationships. In accessibility, semantic models are used to provide screen reader users and other assistive technology users with a higher-level understanding of page content, reducing the cognitive load of navigating complex web pages element by element and enabling more efficient non-visual interaction.
