  • 1. Research School The 10th Workshop on Multimedia Metadata (SeMuDaTe‘09) SeMuDaTe09 Context-aware Mobile Multimedia Services 2 Dec. 2009 in the Cloud Dejan Kovachev Ralf Klamma Dejan Kovachev and Ralf Klamma December 2th, 2009 Informatik 5 (Information Systems), RWTH Aachen University Bonn-Aachen International Center for Information Technology Lehrstuhl Informatik 5 (Informationssysteme) Graz, Austria Prof. Dr. M. Jarke I5-KoKl-1209-1
  • 2. Research School Agenda  Motivation SeMuDaTe09 2 Dec. 2009 Dejan Kovachev Ralf Klamma  Context-aware systems  Architectural design  Data management  Modeling  Context-aware mobile multimedia services  Discussions Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-KoKl-1209-2
  • 3. Research School Motivation Mobile phones provide a lot of contextual information SeMuDaTe09 2 Dec. 2009  Dejan Kovachev Ralf Klamma  Enrich the multimedia services  Match media context with the user's context  Adaptation and personalization  Interoperability with the existing resources on the web  Community context ⇒ Context-aware applications are the future of mobile Lehrstuhl Informatik 5 (Informationssysteme) computing Prof. Dr. M. Jarke I5-KoKl-1209-3
  • 4. Research School Context-aware systems What is context in software applications? SeMuDaTe09 2 Dec. 2009  Dejan Kovachev Ralf Klamma  Context-aware applications [Day 2001]  Contextual information – In mobile applications: spatial, temporal, environmental, social information, availability of resources [Cadenas et al. 2009]  Context models – Expressed in ontologies – Model the semantics of the user, context and multimedia Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-KoKl-1209-4
  • 5. Research School Architectural Design Cloud computing SeMuDaTe09 2 Dec. 2009  Dejan Kovachev – Enhanced interoperability Ralf Klamma – Scalable resources on-demand [Agraval et al. 2008] [Wright 2009] – Off-loading computation-intensive mobile applications [Chun & Maniatis 2009] – Open-source implementations – Hadoop, Nimbus (~Amazon EC2), Eucaliptus  Semantic Web in the cloud computing model – LinkedData, Geonames, DBPedia, Sindice – Search for people, places, events, and connections on the basis of semantically structured documents found on the Web [Mika &Tummarello Lehrstuhl Informatik 5 2008] (Informationssysteme) Prof. Dr. M. Jarke I5-KoKl-1209-5

Jarke I5-KoKl-1209-7
  • 8. Research School Context-aware Mobile Multimedia Services Specific subset of context-aware applications related SeMuDaTe09 2 Dec. 2009  Dejan Kovachev to multiple media types Ralf Klamma  Combination of context information with the media metadata  Presentation and adaptation of multimedia taking context into account Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-KoKl-1209-8
  • 9. Research School Discussions Confluence of the two mega trends may bring to SeMuDaTe09 2 Dec. 2009  Dejan Kovachev loosely coupled ubiquitous services that have context and are ultimately understood by machines Ralf Klamma  How to bring the semantic computing techniques into the cloud platform?  And what is the real value?  How should the context-aware architecture be structured?
