Content Adaptation

The diversity of presentation contexts for multimedia documents requires document specifications to be adapted. In an earlier work jointly with project-team EXMO, we have proposed a semantic adaptation framework for multimedia documents. This framework captures the semantics of document composition and transforms the relations between multimedia objects according to adaptation constraints. This year, we have shown that relying on document composition alone for adaptation restricts the set of relevant candidate solutions and may even divert the adaptation from authors intent. Hence, we have introduced functional annotations to guide the adaptation process. Theses annotations refine the role of multimedia objects in the document. We have applied this approach to SMIL documents, by embedding functional annotations encoded in RDF. These multimedia documents are then adapted thanks to an interactive adaptation tool [6] .
