- Bryan Klimt, Yiming Yang. 2005. Email Folder Classification using Threads. Abstract: While automatic classification of email is obviously a useful task to study, it is not obvious how to best utilize the rich metadata specific to email to improve the quality of the classification. In this paper, we propose a simple algorithm for using email threads to improve the precision of a personal email assistant’s automatic folder classification. We evaluate the approach on a large email dataset, and confirm the intuition that email threads can be used for high precision but low recall. Futhermore, we experimentally verify the intuition that using threads is hampered in its improvement of a classifier by the redundancy of their information.
