  1. What Can Be Learned From Usage Data Lynn Silipigni Connaway Research Scientist Mark Bendig Systems Analyst ASIST 2003 Annual Conference October 22, 2003

  2. What Can Be Learned • What is being accessed • Subject areas • Types of content • Publishers of content • Depth of access • Perusing • In-depth reading • Number of items accessed • Number of screens/pages accessed • Patterns of access • When accessed • Length of use/activity • Movements within the site and the text • System and interface design

  3. Limitations of Usage Data • Do not know • Who the users are • Usually cannot associate user demographics with usage patterns • Where they get access to the resources • How they use resources • Why they use resources • Massive amounts of data to manipulate
