Yiwei Cao|Ralf Klamma|Min Hu|Matthias Jarke
Nowadays various mobile platforms from PDA, smart phones to iPhones can deliver road warriors or trippers much information. However, most applications are lacking the social intelligence of real companionship. One reason is that community context and spatiotemporal information not well taken into consideration. In this paper we propose an ontology-based model using OWL/RDF. With enhanced interoperability substantial be expressed reasoned across systems. Based on middleware Context-Aware Adaptation Service (CAAS), introduce a tourist guide as proof- of-concept provides users context-aware We employ MPEG-7 MPEG-21 metadata standards realize multimedia adaptation device preferences. The evaluation result proves feasibility shows easy extensibility CAAS.
