When cloud computing meets with Semantic Web: A new design for e-portfolio systems in the social media era

摘要

The need, use, benefit and potential of e-portfolios have been analysed and discussed by a substantial body of researchers in the education community. However, the development and implementation approaches of e-portfolios to date have faced with various challenges and limitations. This paper presents a new approach of an e-portfolio system design based on Private–Public (PrPl) data index system, which integrates cloud computing applications and storages with Semantic Web architecture, making semantic web-based visualisation and advanced intelligent search possible. It also discusses how the distinctive attributes of the PrPl-based digital asset management system can serve as a large-scale robust e-portfolio system that can address issues with scalability, sustainability, adoptability and interoperability. With such a new distinctive design, a large-scale deployment at a state or national level becomes possible at a very cost-effective manner and also such large-scale deployment with intelligent digital asset management and search features create numerous opportunities in education.
