The e-recall environment for cloud based mobile rich media data management

Abstract

With the pervasiveness of mobile and wireless devices and rapid growth of the Internet, the access availability of rich media continues to accelerate in amount, variety, complexity and scale. This has been exemplified by various online media service portals including Flickr, Facebook and Last.fm. Unfortunately, lack of proper data processing techniques has now become major obstacle for effectively personal data management, especially in a mobile environment. While the related technical developments have been attracted a lot of research attentions recently, many open problems still remain unsolved. Among them, two major challenges need to be addressed. The first one is how to construct comprehensive way to describe 1) queries - model user information needs and 2) contents of rich media data. Moreover, size of media data collected by modern personal digital device (PDA) could be huge and will continue to grow. Consequently, fast data processing and associated scalability issues are becoming more important than ever before, and yet, little serious research has been conducted in this field.In this paper, we report ongoing efforts to develop E-Recall system - a novel platform for cloud based mobile rich media data management. It aims to provide an intelligent and comprehensive infrastructure for (1) scalable media data processing, (2) flexible media content sharing and publishing and (3) personalized media content integration under mobile environment.
