Media and metadata management for capture and access systems in electronic lecturing environments
نویسندگان
چکیده
One of the main challenges facing web-based multimedia content creators today is the development of cost-effective digital media content for courseware that is reusable and interoperable. Given this, we propose the design and implementation of a model to manage the multimedia and metadata within a system of related topics in a course that is delivered via electronic lectures. This model not only supports the re-purposing and interchange of a course’s digital media content, but also preserves the semantic dependencies and associated media-mapping, of pre-requisite and co-requisite knowledge within a course. Coarse grain or topic-based segmentations of an electronic lecture are used as building blocks to automatically create new, media-rich, electronic lecture experiences of interest to a user and subject to the constraints imposed by the model.

The call of the editorial of the International Journal of Health Policy and Management regarding the “Need to talk about corruption in health systems” is spot on.
