Generalizing email messages digests.

An email digest is a message that results from the combination of other messages. Mailing list management systems implement digests to let subscribers reduce their email messages frequency. In this paper we address the issue of generalizing this digest technique for any message (i.e. not only issued from mailing lists). By generalizing we mean creating new message combinations while 1) keeping an email centric approach, and 2) generating a compact visualization to assist a user task. We implemented a preliminary prototype as a webmail and we will describe a series of digests providing users multiple visualizations in the context of a meeting planning by email.
