We outline the main elements of what we call polyscopic structuring of information and argue that information needs to be structured accordingly. The principles of polyscopy may both serve as guidelines for creating Topic Maps, and provide orientation for further development of Topic Maps standards and software.

vi CHAPTER 1. OVERVIEW 1

Topic Maps are means for representing sophisticated, conceptual indexes of any information collection for the purpose of semantic information integration. To properly fulfil this purpose, the generation of Topic Maps has to base on a solid theory. This paper proposes the Observation Principle as the theoretical fundament of a future scientific discipline Topic Maps Engineering. SemanticTalk gen...

In dieser Untersuchung werden die drei Lokalen Suchmaschinen Google Maps, Bing Maps und TOnline Maps in einem kombinierten Eye-Trackingund Usability-Test verglichen. Es zeigen sich sowohl Probleme bei der Benutzung einzelner Suchmaschinen als auch übergreifende Ergebnisse, die für die Gestaltung von kartenbasierten Suchmaschinen relevant sind. Wir geben Empfehlungen für die Gestaltung solcher S...

We have developed a formal performance model for centralized and replicated architectures involving two users, giving equations for response, feedthrough, and task completion times. The model explains previous empirical results by showing that (a) low network latency favors the centralized architecture and (b) asymmetric processing powers favor the centralized architecture. In addition, it make...

As Internet video goes mainstream, we see increasing user expectations for higher video quality and new global policy requirements for content providers. Inspired by the case for centralizing network-layer control, we present C3, a control system for optimizing Internet video delivery. The design of C3 addresses key challenges in ensuring scalability and tackling data plane heterogeneity. First...
