Conclusions

Abstract

In Chapter 1 we started by covering the basics of the information retrieval and navigation in cyberspace problem. We have subsequently given a broad overview over the field and have introduced the seven concepts of navigation in cyberspace: linking, searching, sequentialization, hierarchy, similarity, mapping, and agents. Our own Cybertools Hiermap, Navigation Diamond, Viewfinder, Cybermap, and Cybertree cover a broad range of promising new research directions in the hypermedia research community. By integrating dynamic linking and the automatic generation of an overview map, we have created a unique tool set that integrates the best of both worlds. We have extended Cybermap by allowing hierarchical nestings of hyperdrawers. We have also presented a broad range of Cybertool applications. The Cybertools complement existing navigational aids for hyperdocuments and provide a self-sufficient navigation tool for browsing in cyberspace Finally, the Cybertools offer the capability of horizontal growth and easy hypertextualization of nonhypertextual documents without restricting the use of already installed browsing mechanisms. To the best of our knowledge, there is no other system like ours that combines hierarchy, similarity, and mapping concepts to give an overview and quick access to large collections of information.
