Elearning - Rich Media Search

  1. 1. OMNIMEDIA “Intelligent Rich Media Search Platform”
  2. 2. Searchable Media for E-Learning <ul><li>As multimedia are being used to facilitate and enhance teaching and creative learning, making rich media including images and videos searchable are critical in today and future e-learning platform and management system. Traditionally, it's a difficult challenge. Some of the team members have invented an interdisciplinary framework which integrates the state-of-the-art image recognition technology and brain science research from MIT, intelligent cluster algorithm and patentable digital “tagging” technology. </li></ul>
  3. 3. Solution <ul><li>The solution is a community-based, video information-editing web platform, exposes and associates descriptive and searchable text with any digital video file. It is diverging from the traditional closed-environment manual-labor model and the fully artificial intelligent approach to metadata content generation. Instead, our solution is focusing on an automated solution to metadata generation through open, collaborative solutions. </li></ul>
  4. 4. Technology <ul><li>The technology is disruptive because a knowledge-sharing model for rich-media content management reduces maintenance costs and achieves higher production efficiency for metadata generation. The platform simultaneously captures users and learners activities and preferences on the content provider’s own website. It also facilitates incremental and collaborative learning through a open community. </li></ul>
