Nice Tag Ontology : modeling tags as RDF named graphs
14 likes3,751 views
The document discusses the ontology modeling of tags as RDF named graphs, exploring the multifaceted nature of tags which serve as links between resources and their representations. It critiques traditional models that impose a fixed form on tags, instead advocating for diverse representations that capture different usages and dimensions of tagging. The paper proposes a structured representation of tag actions encapsulated in named graphs, incorporating different existing tag models and emphasizing social acts in the tagging process.
