Towards Multimedia Thesaurus Support for Media-based Navigation

This paper describes an open hypermedia system which allows content based navigation and retrieval from both text and non-text media. The system provides a variety of link types including the generic link which, once authored from a particular selection, may be followed from any instance matching that selection. The paper also describes the concept of a multimedia thesaurus and illustrates how it may be used to enhance the navigational capabilities of the system, allowing links to be authored on one representation of an object and followed from a different representation.
