Automatic development and display of context information in structured documents on the world wide web

摘要

A system for retrieving a selected page of a structured document and for automatically developing context information about the selected page. This context information may include a table of contents showing the location of the selected hypertext page in relationship to other hypertext pages. In one embodiment, this context information is inserted into the hypertext page. The so-modified hypertext page may then be transmitted to a remote location for display. Since the context information is automatically developed after retrieval, it need not be manually generated and maintained. For WWW applications, the hypertext page with the context information inserted remains in the HTML format viewable by standard browsers. A powerful and convenient system for browsing through structured documents is thus provided.
