Vision of the tele-TASK Project

In the center of the research work of Prof. Dr. Christoph Meinel and his team in the field of Knowledge Engineering and Web University is the tele-TASK project (tele-Teaching Anywhere Solution Kit). It was started more than 15 years ago when we began to research how Internet and web technologies can be used for supporting teaching (> tele-teaching) and learning (> e-learning). Our vision was to design an easy to use mobile system for recording and broadcasting university lectures and presentations over the Internet in order to develop and test on the one hand new tele-teaching and e-learning concepts and on the other hand to innovative portal and navigation techniques.

Our Research Directions

Over the years tele-TASK turned out to be a very fruitful project which helped us, on one side, to gain valuable experiences and a deeper understanding of e-learning and tele-teaching. On the other side, it inspires us to try our upcoming techniques in the are of Web3.0 - semantic, social, service Web -, and to make them accessible for Web-university (details).

Adaptive E-Lecture Video Outline Extraction Based on Slides Analysis

Xiaoyin Che, Haojin Yang, Christoph Meinel
In Proceedings of 2015 International Conference on Advances in Web-Based Learning (ICWL2015), pages 59-68, Guangzhou, China, 11 2015

DOI: 10.1007/978-3-319-25515-6_6

Abstract:

In this paper, we propose an automated adaptive solution to generate logical, accurate and detailed tree-structure outline for video-based online lectures, by extracting the attached slides and reconstructing their content. The proposed solution begins with slide-transition detection and optical character recognition, and then proceeds by a static method of analyzing the layout of single slide and the logical relations within the slides series. Some features about the under-processing slides series, such as a xed title position, will be gured out and applied in the adaptive rounds to improve the outline quality. The result of our experiments shows that the general accuracy of the nal lecture outline reaches 85%, which is about 13% higher than the static method.
