Contextual Authority Tagging is the use of folksonomies to discover and define cognitive authority through reputation within communities of users. Authority is granted by individual users to other individual users with regard to their perceived domains of knowledge via free text tags or labels. This allows discovery of at least two things, 1) which users in a group are authority figures on a certain topic area, and 2) what areas of expertise a particular user possesses. A basic proposal is laid out along with a few examples to foster communication and thought on this new distributed way to discover cognitive authority.    (LX3)
