Modular Unified Tagging Ontology (MUTO)

Modular Unified Tagging Ontology (MUTO)

From the webpage:

The Modular Unified Tagging Ontology (MUTO) is an ontology for tagging and folksonomies. It is based on a thorough review of earlier tagging ontologies and unifies core concepts in one consistent schema. It supports different forms of tagging, such as common, semantic, group, private, and automatic tagging, and is easily extensible.

I though the tagging axioms were worth repeating:

  • A tag has always exactly one label – otherwise it is not a tag.

    (Additional labels can be separately defined, e.g. via skos:Concept.)
  • Tags with the same label are not necessarily semantically identical.

    (Each tag has its own identity and property values.)
  • A tag can itself be a resource of tagging (tagging of tags).

From the properties defined, however, it isn’t clear how to determine when tags do have the same meaning and/or how to communicate that understanding to others?

Ah, or would that be a tagging of a tagging?

That sounds like it leaves a lot of semantic detail on the cutting room floor but it may be that viable semantic systems, oh, say natural languages, do exactly that. Something to think about isn’t it?
