Abstract (EN):
The Web is rapidly becoming the prime medium for human socialization. The
resources that enable that process (social web sites, blogs, media objects, etc.) present growing
complexity and, collectively, weave an ever more intricate web of relationships. Current
technology for declaring those relationships is predominantly implicit, ambiguous and semantically
poor. As a consequence, their automatic assessment is complex and error prone,
preventing the satisfaction of users¿ needs such as effective semantic searches. To address these
limitations, whilst enabling the explicit declaration of semantically unambiguous relationships
between digital resources, a solution employing structured semantic descriptors and ontologies
was conceived, based on MPEG-21. This paper explains the functioning of the devised
mechanism, and goes beyond that, into the definition of two novel employment venues for it,
at the service of two real-world usage scenarios. These demonstrate the mechanism¿s added
value as a powerful alternative for the semantically aware interconnection of web resources, and
highlight the increased QoE that said mechanism enables.
