A teacher must consider many details when planning and organizing a course. This paper shows how the new Topic Map computer technology can help in this process. The developed Topic Map for the CS knowledge domain is used for the analysis of introductory CS courses, but it can be also applied to other courses, including in noncomputer disciplines. Well-structured Topic Maps may become a solid ba...

As Topic Maps allow a structural representation of knowledge, this structure often needs to be visually presented to end-users. Issues, often contradictory, such as representation and navigation re-

In this contribution, we address exploratory search where a user is faced with an information need concerning a domain he lacks specific knowledge. Based on the work of Delbru et al., which introduced metrics to measure the navigational quality of automatically selected facets for RDF data, we apply those findings to the semantically richer TMDM and show how exploratory search functionality can...

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...
