  1. Discovery of Working Activities by Email Analysis Yueyu Fu & Hong Zhang School of Library and Information Science Indiana University JCDL’03, May 31th, 2003

  2. Outline • Motivation • Visualization Goal • System Design • Conclusion

  3. Motivation Explore working activity involved in email communication using Treemap algorithm.

  4. Background • Use of Email • Communication • Personal archiving • Task management • Problem As the number of email we exchange increase at a high rate, it’s getting hard to manage personal email box. • Related research • Thread – based Visualization • Time – based Visualization • Examples: Timestore, Outlook 2000 and NEC’s VisualMail

  5. Visualization Goal • Goal- Explore working activity involved in email communication using Treemap algorithm. • User Analysis • Intended audience - any one communicating extensively with others by email. For instance, programmers email each other to solve programming bugs. • Task Analysis • Identify the email patterns by the sender information • Identify the email patterns by the subject information • Display email content

  6. Data Analysis & Data Mining • Dataset size: 1695 emails • Data format: MS Access table • Dataset topic: Software development • Data attributes: subject, sender, body, receiver, & etc.

  7. Hierarchical Structure of Dataset

  8. Design • Each email will be represented as a rectangular in the Treemap. • Two interfaces will be provided. • Emails will be grouped together by subject or sender. • The colors represent different subjects or senders. • Quick tooltip will be shown when the mouse is placed over a specific rectangular. • After clicking the rectangular assigned to an email, a pop-up window containing email content will be shown. • The control panel will allow user to manipulate the Treemap to get an optimal view.

  9. User Interface Overview

  10. Interface I – Individual activities

  11. Interface II – Component distribution

  12. Interactive Function: Tooltip

  13. Interactive Function: Pop-up Window
