From Personal Notes to Linked Social Media
Dragan, Laura (National University of Ireland, Galway) | Passant, Alexandre (National University of Ireland, Galway) | Groza, Tudor (National University of Ireland, Galway) | Handschuh, Siegfried (National University of Ireland, Galway)
Semantic technologies are available, and gain popularity on the Web as well as on the desktop, but both (desktop and Web) act as large data silos, making personal and online data difficult to interlink. We propose a system that enables easy publishing of personal notes as linked social media content, while at the same time semantically enriching the desktop resources with information retrieved from the Linked Data cloud. The transformation, publication and linking process is integrated with the familiar desktop applications and online blogging platforms, providing a better usability experience.
Anatomy Learning with Virtual Objects
Stull, Andrew T. (University of California, Santa Barbara) | Hegarty, Mary (University of California, Santa Barbara) | Mayer, Richard E. (University of California, Santa Barbara)
In 3 experiments, participants learned bone anatomy by using a hand-held controller to rotate an on-screen 3D bone model. The on-screen bone included (OR condition) or did not include (no-OR condition) orientation references—visible lines marking its axes. The learning task involved rotating the on-screen bone to match target orientations. Learning outcomes were assessed by having participants identify anatomical features from different orientations. On the learning task, the OR group performed more accurately, directly, and quickly than the control group and high-spatial individuals outperformed low-spatial individuals. Assessments of anatomy learning indicated that under more challenging conditions, ORs elevated learning by low-spatial individuals to near that of high-spatial individuals. In Experiment 3, orientation references were shown to help learners avoid disorientation due to the symmetrical shape of the object.
Speech Technology for Information Access: a South African Case Study
Barnard, Etienne (Meraka Institute, Council for Scientific and Industrial Research) | Davel, Marelie H. (Meraka Institute, Council for Scientific and Industrial Research) | Huyssteen, Gerhard B. Van (Meraka Institute, Council for Scientific and Industrial Research)
Telephone-based information access has the potential to deliver a significant positive impact in the developing world. We discuss some of the most important issues that must be addressed in order to realize this potential, including matters related to resource development, automatic speech recognition, text-to-speech systems, and user-interface design. Although our main focus has been on the eleven official languages of South Africa, we believe that many of these same issues will be relevant for the application of speech technology throughout the developing world.
The New Empiricism and the Semantic Web: Threat or Opportunity?

Prototype Optimization for Temporarily and Spatially Distorted Time Series
Hartmann, Bastian (University of Applied Sciences Karlsruhe) | Schwab, Ingo (University of Applied Sciences Karlsruhe) | Link, Norbert (University of Applied Sciences Karlsruhe)
An important issue in time series classification problems is to find representative prototypes. Especially for roughly segmented time series with spatial distortions, such as human gestures, it is complicated to find templates, which optimally represent signal classes. In this paper we present an approach to find optimal time series prototypes in subseries of class templates. Our optimization approach is based on separability measures for prototype candidates and utilizes (but is not limited to) DTW in order to tackle the problem of spatial and temporal distortions. The search for prototypes in the target space is performed by means of a brute force search as well as an evolution strategy. In our experiments with an artificial dataset we show that brute force search optimization is able to improve the time series classification result and that the application of an evolution strategy yields comparable target function scores while reducing computing time.
The Privacy Paradox
Zallone, Raffaele (Studio Legale Zallone)
The present privacy legislation continue to be drafted on the basis of the Strasburg Convention of 1981. The mere fact that present privacy laws are based on principles drafted 29 years ago, when the web did not exist, shows that privacy legislation need to make a quantum leap to be in line with the realities of to-day’s real life operating environment. If the status quo is kept, the law and its application shall face serious (and sometimes insurmountable) obstacles to its implementation, making compliance costly for private business, at the same time jeopardizing effectiveness of privacy protection for individuals. A new set of rules should be drafted and established, addressing the changed environment of information and communication technology, in order to allow free flow of information at the same time assuring due protection of personal data.

First, today's Internet in audio navigation from using CF. is mostly in English and is thus largely inaccessible to A useful distinction among CFbased approaches arises billions of people for whom English is not a native or second from the types of data used to associate users to products language. Second, today's Internet is accessible largely and other items.

Physics With Robotics — Using LEGO MINDSTORMS In High School Education
Church, William Joseph (Littleton High School) | Ford, Tony (Redcliffe State High School) | Perova, Natasha (Harvard Graduate School of Education) | Rogers, Chris (Tufts University)
Integrating robotics activities in science curriculum provides rich opportunities to engage students in real world science and help them to develop conceptual understanding of physics principles through the process of investigation, data analysis, engineering design, and construction. In addition, students become more confident learners and develop better problem-solving and teamwork skills. In this paper we describe a successful use of LEGO® MINDSTORMS® in designing robotics-based activities for teaching high school physics classes. Students design and perform novel science investigations with a toolset that helps them achieve a high reproducibility in their experimental designs. Several example projects that utilize LEGO MINDSTORMS are presented.
Wikipedia Missing Link Discovery: A Comparative Study
Sunercan, Omer (Middle East Technical University) | Birturk, Aysenur (Middle East Technical University)
In this paper, we describe our work on discovering missing links in Wikipedia articles. This task is important for both readers and authors of Wikipedia. The readers will benefit from the increased article quality with better navigation support. On the other hand, the system can be employed to support the authors during editing. This study combines the strengths of different approaches previously applied for the task, and adds its own techniques to reach satisfactory results. Because of the subjectivity in the nature of the task; automatic evaluation is hard to apply. Comparing approaches seems to be the best method to evaluate new techniques, and we offer a semi-automatized method for evaluation of the results. The recall is calculated automatically using existing links in Wikipedia. The precision is calculated according to manual evaluations of human assessors. Comparative results for different techniques are presented, showing the success of our improvements. We employ Turkish Wikipedia, we are the first to study on it, to examine whether a small instance is scalable enough for such purposes.
