This paper presents an approach to the problem of mapping ontologies. The motivation for the research stems from the Diogene Project which is developing a web training environment for ICT professionals. The system includes high quality training material from registered content providers, and free web material will also be made available through the project’s “Web Discovery” component. This invo...

The millions of web pages populating the internet seem to be unstructured and chaotic, but there are implicit semantic relations between them. In this paper we propose to make explicit the underlying semantic structure of the internet, by measuring joint keyword occurrences in web pages, around our notion of “Semantic Contexts”. As a result, we can draw a “map” of semantic clusters which can be...

Concept maps have long provided visual languages widely used in many different disciplines and application domains. This article reports experience in taking an existing open architecture concept mapping tool and making it available on the web in a number of ways: as a client helper downloading and uploading concept maps; as an active controller of the browser, indexing multimedia material thro...

A tool to generate a vector based visualization of geographic information has been developed at the University of Osnabrück. The web mapping application uses SVG and implements some interaction functionalities. In addition, the application can be used to visualize further georeferenced information, such as weather or traffic data. By using vector graphics it is possible to zoom into a region wi...

People implicitly associate different emotions with different locations in left-right space. Which dimensions of emotion do they spatialize? Across many studies people spatialize emotional valence, mapping positive emotions onto their dominant side of space and negative emotions onto their nondominant side. Yet, other results suggest a contradictory mapping of emotional intensity (a.k.a., emoti...

In this article, we describe an infrastructure enabling archetype-based semantic interoperability of Web Service messages exchanged in the health care domain. We annotate the Web Service messages with the OWL representation of the archetypes. Then, by providing the ontology mapping between the archetypes, we show that the interoperability of the Web Service message instances can be achieved aut...

An Internet mapping application is being introduced in conjunction with the release of the second version of the Community Health Status Indicators (CHSI) Report. The CHSI Geographic Information Systems (GIS) Analyst is an easy-to-use Web-based mapping application that provides new opportunities for the visualization, exploration, and understanding of the indicators. Indicators can be mapped an...

The GenW2 project (Generalization for portrayal in Web and Wireless mapping) has recently started and aims at developing new methods for web and wireless mapping with the main focus on integration of heterogeneous information and on-the-fly map generalization in a mobile context. The poster discusses the first step of a proposed methodological framework for future mobile GIS and mapping scenarios.

In this initial study, we explore how recent advances of mobile and web-based technologies can be utilized to support seamless knowledge building processes and to enhance contextualized learning experiences across multiple locations. Using design research as a methodological framework, we analyzed current practices and configurations of mobile learning in one primary school in Singapore, and co...
