  1. Semantics in Multimedia Content for Multimedia Use Steffen Staab http://isweb.uni-koblenz.de

  2. Semantics: What for? Tasks & Purpose • Find me pictures about a boy on the beach • Find me cute pictures about Nico to show to my Mum • Find me pictures from Turkey • Find me pictures from our common holiday • with a resolution of …. • with no other person in the foreground…

  3. Multimedia Semantics • Content semantics (general knowledge): boy; beach; jet ski; sea; sky • Content semantics („private knowledge“): Nico digging • Retrieval semantics: cute picture to show • Situational semantics: Side, Turkey, 2005 • Social semantics: Vacation with friends 05

  4. Multimedia Semantics Human perspective Technical perspective common vacation Multimedia social semantics Multimedia retrieval semantics cute Multimedia situational semantics Turkey boy Multimedia content semantics And semiotics will tell you that this list is incomplete…

  5. Multimedia Semantics common vacation Manual Class. & Mgmt Multimedia social semantics Feedback & AutoClassify Multimedia retrieval semantics cute Capture (during creation) Multimedia situational semantics Turkey Extract from (image) data boy Multimedia content semantics

  6. Find me a cute picture of Nico digging during our common vacation Manual Class. & Mgmt Feedback & AutoClassify Capture (during creation) myCal Extract from (image) data

  7. Ontology sand texture common vacation cute Turkey boy myCal Core Question for Multimedia Use: How should this ontology look like? Is it (like) MPEG-7 ?

  8. What is the Problem with MPEG-7? Segment 1 Segment 2 Segment 3 <Mpeg7> <Description xsi:type="ContentEntityType"> <MultimediaContent xsi:type=„ImageType"> <Image> <SpatialDecomposition> <StillRegion id=„SR1“> <TextAnnotation> <KeywordAnnotation xml:lang="en"> <Keyword>Sky</Keyword> </KeywordAnnotation> </TextAnnotation> </StillRegion> <StillRegion id=„SR2“> <Semantic> <Label> <Name>Sky</Name> <Label> </Semantic> </StillRegion> <StillRegion id=„SR3“> <Semantic> <Definition> <!-- Also TextAnnotation!! --> <StructuredAnnotation> <WhatObject> <Name xml:lang="en">Sky</Name> </WhatObject> </StructuredAnnotation> </Definition> </Semantic> </StillRegion> ... How do you formulate a query to get all segments that show „Sky“? First Shot: XQL: //StillRegion[.//Keyword=“Sky”]

  9. Conclusion Sharing & Tagging systems Multimedia social semantics Semantic querying Multimedia retrieval semantics Process support Multimedia situational semantics Constraint reasoning Multimedia content semantics
