    Email-Set Visualization: Facilitating Re-Finding in Email Archives
    Gorton, Douglas; Murthy, Uma; Vemuri, Naga Srinivas; Pérez-Quiñones, Manuel A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2007-05-01)
    In this paper we describe ESVT – EmailSet Visualization Tool, an email archive tool that provides users a visualization to re-find and discover information in their email archive. ESVT is an end-to-end email archive tool that can be used from archiving a user’s email messages to visualizing queries on the email archive. We address email archiving by allowing import of email messages from an email server or from a standard existing email client. The central idea in ESVT’s visualization, an “email-set”, is the set of emails that are the result of a query on a user’s email archive. ESVT provides a multiple email-set view - visualization of multiple email-sets on a time axis. In addition, each email set can be individually visualized based on person and time axis, using the single email-set view. Query logs, individual email visualization, multiple email set visualization provide rich contextual cues, thus enabling end users to deal with email overload and re-find past email which otherwise wouldn’t be discovered easily.

    Extending the 5S Digital Library Framework: From a Minimal DL Towards a DL Reference Model
    Murthy, Uma; Gorton, Douglas; Torres, Ricardo da Silva; Goncalves, Marcos A.; Fox, Edward A.; Delcambre, Lois M. L. (2007-06-23)
    In this paper, we describe ongoing research in three DL projects that build upon a common foundation: the 5S DL framework. In each project, we extend the 5S framework to provide specifications for a particular type of DL service and/or system - finally, moving towards a DL reference model. In the first project, we are working on formalizing content-based image retrieval services in a DL. In the second project, we are developing specifications for a superimposed information-supported DL (combining annotation, hypertext, and knowledge management technologies). In the third effort, we have used the 5S framework to generate a practical DL system based on the DSpace software.
