VideoLecturesMashup: Using Media Fragments and Semantic Annotations to Enable Topic-Centred e-Learning

摘要

In this demo, we present the VideoLecturesMashup, which delivers re-mixes of learning materials from the VideoLectures.NET portal based on shared topics across different lectures. Learners need more efficient access to teaching on specific topics which could be paxt of a larger lecture (focused on a different topic) and occur across lectures from different collections in distinct domains. Current e-learning video portals can not address this need, either to quickly dip into a shorter part focused on a specific topic of a longer lecture or to explore what is taught about a certain topic easily across collections. Through application of video analysis, semantic annotation and media fragment URIs, we have implemented a first demo of VideoLecturesMashup.
