Semantic Bookmarking

A web navigation technique that associates saved page locations with meaningful conceptual labels from a domain ontology rather than with specific structural positions in the HTML code. Unlike traditional bookmarks that reference a URL or a position in the document's DOM tree and break when the page structure changes, semantic bookmarks identify content by what it means rather than where it is located. This makes them resilient to page redesigns and enables them to work across multiple websites within the same domain. Semantic bookmarking is particularly valuable for non-visual web access, where efficient content retrieval is critical to reducing the time blind users spend navigating pages.
