If you're hosted on premise, your system administrator can query the analytics database to pull that information. (Content, tags, categories) I'd assume Jive could do the same for hosted/cloud.
If you have Advanced Gamification (Bunchball) you can run a report of all activity (filter to only generate a report that just includes "tagname"). Te report will include a list of every time someone used a tag, and what container it was in. The downside here is that you don't know what the tag is, just its numerical id.
