Abstract
The large number of video lectures within digital archives is making critical the indexing and retrieval process. Indeed, most of the systems base the indexing process on few generic text information (e.g., course title and teachers name) and this creates problems to students who are looking for very specific topics and hence want to browse video in details. Moreover, additional metadata could pro-vide useful information to those users who access the educational materials by means of assistive technologies. In this systems, we propose an approach that allows students to take on-the-y notes while watching a video lecture and uses these notes to enrich video lectures with metadata that will be helpful to the indexing and retrieval process. In particular, to allow detailed video browsing, our proposed Social Learning (SOLE) system defines a set of eight pre-defined tag- notes and segments the lecture into a sequence
of video chapters. Students can use the textual notes to describe and to retrieve the video material, providing hints about its content to users with special needs. To evaluate our approach, we developed a proto-type version of SOLE and we asked for volunteer evaluators. Results showed that users feel comfortable in taking notes while watching a video and liked to browse video lectures using notes. According to the results obtained in the evaluation, both students and video lecture providers might appreciate the proposed approach
