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...

The FWI-tel instantaneous is a system for computing a forest fire risk index; it elaborates instantaneous weather maps to evaluate fire risk indicator on alpine regions. This system is based on the previsional Canadian Fire Weather Index (FWI) adjusted for continental Europe latitudes and climatology and adapted to alpine regions orography. FWI is a meteorological index, which uses as input dat...

Data fusion aims at integrating multiple data sources that can be redundant or complementary to produce complete, accurate information of the parameter of interest. In this work, data fusion of precipitable water vapor (PWV) estimated from remote sensing observations and data from the Weather Research and Forecasting (WRF) modeling system are applied to provide complete grids of PWV with high q...

Maps, showing the tactical or the administrative situation at any particular time, play a central role in disaster management. They can be realized as interactive map mashups. In addition to classical information (weather, water levels, energy network, forces), they can also be used to present a view on citizen-generated content, e.g. from social media. In this paper we offer insights into how ...

The National Weather Service (NWS) recently began providing static inundation maps at selected river forecast points through the Advanced Hydrologic Prediction Service (AHPS) web pages. Positive feedback has motivated efforts to expand the forecast mapping program. In order to expand this mapping program efficiently and effectively, we need a more objective basis for determining where static fo...

Our task is to provide situational awareness for the complex logistical task of directing the movement of U.S. Marines and material over rugged terrain, day and night, in uncertain weather conditions. This difficulty is multiplied by the well-known dangers of amphibious assault, long considered the most difficult problem in warfare. Even with the advent of computers and sophisticated decision-m...
