    An update classification system has been developed[1] that injects JavaScript code into a Web page. This code monitors the page for updates, then classifies and presents the changes. This report describes a technical evaluation of the code, which was injected using a Google Chrome extension. 20 of the Alexa top 25 Web pages were tested, resulting in interaction with 100 different instances of dynamic content. Classification was found to be correct in all cases, although the update aggregation system did not always perform as expected.
