Interesting review of issues around ontologies and tools for “social tagging” posted on KnowledgeBoard by Silverio Petruzzellis. Not digested the quality of any analysis yet, but it’s comprehensive with a plethora of links (naturally) including Clay Shirky’s “Ontology is Overrated”.
As I keep saying it’s not ontology that’s overrated, but the idea that it’s fixed or pre-ordained. What social tagging does is allow an appropriate ontology to evolve. The best kind.
