Navigate to the Central Administration. Click on Application Management. Click on Manage service applications which is available under Service Applications. Click on MMS (Managed Metadata Service). Expand MMS termstore in the Taxonomy Term Store where all the groups for that particular termstore will be displayed. I have a group called “SP2013” which has the following term sets and terms

Ø Apps

Ø BCS

Ø External Content Type

Ø External Data Column

Select the term on the right hand side you could be able to see the term properties. I have the following labels for the term External Content Type
