2 Information Systems & Semantic Web University of Koblenz ▪ Landau, Germany Semantic Web as a Knowledge Infrastructure for Multimedia Steffen Staab

3 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 3 of 28 Depict ISWeb People! Context is missing! Precision 12/12 Recall 12/19 (FTE)  12/33 (all) 

4 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 4 of 28 Depict ISWeb People! There is a picture of ISWeb in 2006 in the Wiki!

5 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 5 of 28 Depict ISWeb People! Some more ISWeb members you find on our Web page!

6 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 6 of 28 Depict ISWeb People! Outside of our Web Site you may also discover current members…

7 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 7 of 28 Depict ISWeb People! For others, you need to integrate information from the Web and from Word documents of my mailbox

8 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 8 of 28 Knowledge Infrastructure A Multimedia objects exist in an environment. This environment (context) can and should be used to find, access and present the objects. Knowledge about Multimedia Objects exists in an environment, too. This knowledge infrastructure can and should be used to find, access and present the objects. Well, known in the multimedia field Little explored until now

9 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 9 of 28 Structure of the Environment  Knowledge in Portal  Knowledge in File System  Knowledge in Wiki  Knowledge in Outside Service  Knowledge in Mailbox

10 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 10 of 28 Structure of the Environment 1.Collect or Access 2.Harvest/Query Knowledge 3.Collect & Organize Knowledge 4.Use Knowledge

11 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 11 of 28 What does the Knowledge Infrastructure need? 1.Ontologies  Multimedia Ontologies  Context Ontologies  Domain Ontologies 2.APIs 3.Querying and reasoning

12 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 12 of 28 How to structure this knowledge? PersonRegion

13 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 13 of 28 Scenario The "ISWeb" at Bad Kreuznach (team web page)ISWeb Localize a region (person) Annotate the content (interpretation) Carsten Saathoff, aceMedia Project lead, ISWeb, Semantic Multimedia, KAT Annotation Tool Link to knowledge on the Web :Reg1 foaf:depicts kodemaniak:me kodemaniak:me rdfs:label “Carsten Saathoff" kodemaniak:me rdf:type foaf:Person Reg1 Summer School Semantic Web-05 (video)video

14 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 14 of 28 Problem The "ISWeb" at Bad Kreuznach (team web page)ISWeb Summer School Semantic Web-05 (video)video Seq1 Seq4 Multimedia objects are complex  Compound information objects, fragment identification Semantic annotation  Subjective interpretation, context dependent Linked data principle  Open to reuse existing knowledge  Multimedia O  Domain O  Context O Reg1

18 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 18 of 28 … Contextualized Information Metadata from contexts other than file browsing is not available, we cannot  inspect conversations in which a file took part  find out about the web page from which it was downloaded  view the event description for which it was created  see the task it is associated with (as input or output) Bercovici.pdf No am “I apply for this position. Here is my cover letter and CV...” Colleagues Context of multimedia information is lost

19 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 19 of 28 … Communicating VoIP Stef fen No am Communication Context of multimedia information is lost

20 ISWeb - Information Systems & Semantic Web Steffen Staab MMKM 20 of 28 …classifying information… Classification of multimedia information is lost
