Abstract: There is disclosed an improved user interface for a network, for example the Internet. If a user clicks on an incorrect hyperlink then the system, instead of merely informing the user that an error (e.g. “404 Not Found” error—meaning that the requested web page is not available) has occurred, provides the user with a list (503) of hyperlinks to alternative web pages. The alternative web pages are related to the context of the web page that was originally requested by the user (but was not available, due to the incorrect hyperlink, to the user). In a preferred embodiment (300), the system analyzes a web page (201) (i.e. the web page that contained the incorrect hyperlink) for context information and uses the context information to improve the relevance to the user of the list (503). The system may also analyze other web pages for context information.
