Presenting Knowledge on the Semantic Web

Long-term goal

• Develop knowledge-intensive models and document processing technologies that are able to:

generate coherent multimedia presentations tailored to an individual user

taking into account their preferences, abilities, device capabilities and environment.

(5)

Goals of research

• Understand how to

– incorporate design and discourse knowledge into multimedia presentations

– represent this knowledge in Web and Semantic Web technologies

• Semantic Web provides

– source content for inclusion in presentations – a means of expressing knowledge needed

Space/time trade-offs

Space/time trade-offs

• Media repository from Rijksmuseum

• Quantitative constraints insufficient using pixel-based positioning

• Qualitative constraints also used

specification of constraints at higher level

A not-overlap B, B after C

• If insoluble then backtrack to other solutions using Prolog

Semantic graph to presentation

• DISC

• Rijksmuseum repository of media items

• Semantic graph is not enough

Rembrandt married-to Saskia also need discourse structures

for deriving grouping, ordering and priorities
