Search Patterns Through a Health-Information Site

by Sokoloff, Jason

Abstract (Summary)
This study considers the impact of taxonomy development on user query-expansion patterns at NC Health Info, a Web database of North Carolina online health and medical resources. In consideration of simplifying NC Health Info’s taxonomy, user session logs were analyzed for selection frequency of general and specific topics and directional patterns between general and specific topics as initial and subsequent selectors. Based on a sampling of session logs over a seven-month period, users exhibited no clear preference for general or specific topics. In an analysis of topics deemed crucial to North Carolinians by a governor’s task force, patterns illustrated a significant preference for specific topics over general topics. This research, and the results of previous studies regarding taxonomy development and query-expansion, suggests that a simple taxonomy would less effectively serve users.
