Abstract
Enterprise communication applications rely on automated
reasoning about factors such as expertise for connecting people.
Quantifying expertise is necessary for such applications because
of the time constraints imposed by communications routing. This
paper discusses the potential for collaborative tagging in the
enterprise and how it enables the formation of social networks
around tags or topics. These social networks are reflective of the
interests and expertise of users contributing to the tag. The
tagging activity of a user contributes to the expertise of the user
and influences the expertise of other users. The paper proposes a
ranking mechanism for expertise based on the tagging activity of
users for both unstructured and structured tag spaces. The paper
also briefly describes a communication platform that will
incorporate the ranking mechanism.
