One of the key aspects in the development of LarKC is how to evaluate the performance of the platform and its constituent components in order to guarantee that the execution of a pipeline will match the user’s needs and provide the desired solutions (answers) to the user’s queries. Therefore, in this deliverable, the first in a series three documents concerned with the definition of a Framework for Measuring and Evaluating Heuristic Problem Solving, we make the first steps towards defining such framework by considering the theoretical foundations and principles of evaluation and measurement theory, discussing several important aspects related to …

We present an error metric based on the potential energy of water flow to evaluate the quality of lossy terrain simplification algorithms. Typically, terrain compression algorithms seek to minimize RMS (root mean square) and maximum error. These metrics fail to capture whether a reconstructed terrain preserves the drainage network. A quantitative measurement of how accurately a drainage network captures the hydrology is important for determining the effectiveness of a terrain simplification technique. Having a measurement for testing and comparing different models has the potential to be widely used in numerous applications (flood prevention, erosion measurement, pollutant propagation, etc). In this …

Computer Science Presentations And Conference Materials
We often learn of successful pedagogical experiments, but we seldom hear of the the ones that failed. For this special session we solicited submissions from the SIGCSE membership, selected the best from among these, and will have presentations at the session by the selected authors. Our contributions describe pedagogical approaches that seemed to be good ideas but turned out as failures. At the session, contributors will describe their pedagogical experiment, the rationale for the experiment, evidence of failure, and lessons learned.

Departmental Papers (CS)
Users of help systems often complain that they do not find them useful; while they still use help at least occasionally, they resort to other problem-solving strategies. In this paper, we analyze audiovisual recordings of people using a computer application, to identify (1) transition patterns among problem-solving approaches, and (2)the frequency of these transitions. Our analysis indicates that people switch frequently between consulting help and exploring the interface. Switching between problem-solving approaches appears to be an effective way of succeeding in tasks. Applications and their help systems can be better designed to support users who switch between help and non-help …

Correlation Of Music Charts And Search Engine Rankings, Martin Klein, Olena Hunsicker, Michael Nelson

We investigate the question whether expert rankings of real-world entities correlate with search engine (SE) rankings of corresponding web resources. We compare Billboards "Hot 100 Airplay" music charts with SE rankings of associated web resources. Out of nine comparisons we found two strong, two moderate, two weak and one negative correlation. The remaining two comparisons were inconclusive.
