Can I set an specific term set for the enterprise keyword? The default Term set is System/Keywords but let's say that I have a enterprise keyword in 2 different content types so in content type A the keywords has an specific meaning and in the Content type B the keywords has a different meaning, so it's there a way to set the term set for an enterprise keyword so I can have the functionality of the field but my final term set is different for each one of them?
The Enterprise Keywords feature of SharePoint 2013 is using the OOB term set only. So I think that your idea can not be realized in that way.
