Transcript

  • 1. The 10th Workshop on Multimedia Metadata (SeMuDaTe‘09) Multimedia Processing on Multimedia Semantics SeMuDaTe‘09 and Multimedia Context Yiwei Cao Ralf Klamma Dejan Kovachev Yiwei Cao, Ralf Klamma, and Dejan Kovachev Informatik 5 (Information Systems), RWTH Aachen University 2.12.2009 Graz, Austria Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-1
  • 2. Agenda  Introduction – Motivation and problems SeMuDaTe‘09 – Terminologies  The multimedia information processing model Yiwei Cao Ralf Klamma – Multimedia metadata management – Commsonomy: Folksonomy on community Dejan Kovachev  Conclusions and discussions Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-2
  • 3. Introduction  Context awareness is important for mobile multimedia applications SeMuDaTe‘09 Yiwei Cao Ralf Klamma Dejan Kovachev  Uncertain information everywhere  Is semantics “only grasped” in context?  Use of multimedia semantics and context information Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-3
  • 4. A Framework for Mobile Multimedia Data Management with Uncertainty SeMuDaTe‘09 Yiwei Cao Ralf Klamma Dejan Kovachev Lehrstuhl Informatik 5 (Informationssysteme) (Cao et al. in IJCSSE) Prof. Dr. M. Jarke I5-CKKo-1209-4
  • 5. Recall the Scenario for Multimedia Semantic Context Management  Context data to enhance multimedia semantics – GPS data -> Tribunes, Curves, etc. (Places) SeMuDaTe‘09 – Time data -> Lap, Start, Finish, Box stop, etc. (Events) – Racing car data –> Ferrari, McLaren-Mercedes, BMW-Sauber Community, etc. (Agents)  For context-aware mobile community information systems Yiwei Cao Ralf Klamma Dejan Kovachev Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-5
  • 6. Multimedia Semantics and Multimedia Context  Context in computer science: Multimedia Multimedia situational or environmental semantics context information [Abowd et al., 1999 ] Computing SeMuDaTe‘09 Context awareness Meaning  context – For multimedia input – For multimedia search User Yiwei Cao Richness Ralf Klamma context Dejan Kovachev – For multimedia retrieval  Information richness Physical [Daft & Lengel, 1986] Precision context  Problem: multimedia semantics and multimedia Machine Time/ readability location context are not well combined for mobile multimedia Community Lehrstuhl Informatik 5 (Informationssysteme) information applications Context Prof. Dr. M. Jarke I5-CKKo-1209-6
  • 7. Multimedia Metadata  Multimedia metadata in use – To enable data exchange with enhanced data interoperability SeMuDaTe‘09 – To label multimedia items – To describe multimedia collection items – To record authenticity and access evidence Yiwei Cao Ralf Klamma  MPEG-7 Dejan Kovachev – Rich multimedia content description + – Flexible schema + – Ambiguous semantics of elements - – Complexity - – Large overhead for data transfer - Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-7
  • 8. Metadata Crosswalks  Media interoperability and community heterogeneity – Multimedia interoperability enhancement through metadata standards SeMuDaTe‘09 – Strengthened by interdisciplinary cooperation within professional communities – Crosswalks of metadata standards: schema mapping Multimedia technologies: MPEG-7, MPEG-21 Heritage preservations: CIDOC CRM, Dublin Core Yiwei Cao Ralf Klamma Dejan Kovachev Geography and cartography: OGC GML, KML  Metadata for multimedia semantics and multimedia context − Multimedia semantics annotation as metadata − Multimedia context expression as metadata − User generated media and tagging Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-8
  • 9. Commsonomy  Ontology does not work alone for multimedia semantics  Community based Folksonomy defined and used within and across SeMuDaTe‘09 communities of practice  The triple model shows relationships between – Users – resources (the tag model) – Resources – resources (the RDF model) Yiwei Cao Ralf Klamma Dejan Kovachev  Do communities of practice use different tags for their domains? – Four aspects: users tag resources in communities – Collaborative: how users from different communities tag differently on the same resource? – Community based tag clouds? Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-9
  • 10. The Multimedia Information Processing Model SPARQL Multimedia SeMuDaTe‘09 resources MPEG-7 Ontology A (Commsonomy) Yiwei Cao Ontology B Context Dublin Core Ralf Klamma OWL Dejan Kovachev Precise RDFS Domain multimedia TV-Anytime Information query results RDF EXIF Community of ... Practice (CoP) Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-CKKo-1209-10
  • 11. Conclusions and Discussions  Use of multimedia semantics and multimedia context in combination  Open questions on multimedia uncertainty SeMuDaTe‘09 – How precise need multimedia semantics be? – How precise need multimedia context be? Multimedia Multimedia Yiwei Cao Ralf Klamma semantics context Precise Dejan Kovachev Precise computing agent, context object Uncertain User Demo: Uncertain context concept Virtual Campfire - Uncertain physical Collaborative Precise context event Multimedia Precise Semantization Uncertain time with Mobile Social status Software Lehrstuhl Informatik 5 Uncertain (Informationssysteme) Prof. Dr. M.
