Content based navigation in an open hypermedia environment

摘要

Microcosm is an open hypermedia architecture for developing large scale multimedia systems. Among many other features, Microcosm introduces two link types, generic and dynamic links, which substantially reduce the authoring effort required for hypermedia system development. Generic and dynamic links were initially designed to provide content based navigation and content based retrieval for text documents respectively. Recently the Microcosm architecture has been extended to facilitate generic and dynamic links from non-text media. Generic links from non-text allow the user to author a generic link from an image object in one image and follow the link from a similar image object in another image. Similar facilities are described for authoring links from video and sound files.
