Modelling Context-Aware Multimedia Community Content on Mobile Devices

Abstract

Community services play a steadily growing role in the current World Wide Web. Especially services that provide video or other multimedia content - in particular user-generated content - enjoy great popularity. With the integration of multimedia technology like video cameras or -players into mobile devices these services could also be used while on the move. Some mobile devices are already equipped with GPS receivers, compasses, thermometers and so on and therefore can be used for so called context-aware services. This allows for a variety of new, content-based community services.

This paper introduces a metadata model that takes important features of context-aware multimedia community content on mobile devices into account. The model is used for automatic preselection and filtering of content based on context. Besides the annotation of multimedia content with context, it supports the linkage between content and associated comments and the definition of access rights for different communities and its members. The proposed model is mapped on the MPEG-7 standard, a generic description tool for multimedia metadata.
