Augmented browsing describes the experience of using a system that can automatically augment or improve the information in web pages. For example, augmented browsing could be used to automatically add definitions for all scientific or technical keywords that occur in a document. A popular example of an augmented browsing technology is the Firefoxadd-onGreasemonkey, which allows end-users to install scripts that make on-the-fly changes to HTML-based web pages.
Augmented browsing allows end-users to personalize how they view web documents, and is believed by some[who?] academics to be an important emerging technology.
