Activity-centric search in email

We consider activity-centered tasks in email, including the novel tasks of predicting future involvement of persons from the enterprise in an ongoing activity represented by a folder, and a novel task where we identify email messages that are related to a to-do item. We also evaluate the task of email tagging to folders, where multiple choice is allowed, and an inverse task, of finding messages relevant to a folder associated with an ongoing project. Empirical evaluation using real world email data, applying a graph based link analysis method and a vector-space model, shows potential utility to facilitate activity management in email.
