Hall, Catherine E. and Zarro, Michael A. (2011): What do you call it?: a comparison of library-created and user-created tags. In: JCDL11 Proceedings of the 2010 Joint International Conference on Digital Libraries 2011. pp. 53-56. Available online

In this paper, we describe an exploratory study comparing the abstracting and indexing practices of a semi-expert LIS community (metadata creators for the digital library, ipl2) and the social tags generated by Delicious users for the same corpus of materials. We find over 88% of the resources in the ipl2 History collection were tagged at least once in Delicious. Overlap between the tags applied to ipl2 resources and indexing shows terms that the two groups are similar enough to be useful, yet dissimilar enough to provide new access points and description.

Yang, Christopher C., Winston, Flaura, Zarro, Michael A. and Kassam-Adams, Nancy (2011): A study of user queries leading to a health information website: AfterTheInjury.org. In: Proceedings of the 2011 iConference 2011. pp. 267-272. Available online

AfterTheInjury.org is a direct to health consumer, empirically-grounded Web-based program that is hosted by an academic medical center. Launched in 2009, it includes information and psycho-education interventional content for parents of injured children. This study analyzes search engine queries that led users to the website in order to better understand the informational needs of users of such a website. Query data were collected for the 2009 calendar year via Google Analytics, a widely used free website statistics and traffic analysis tool. Specific analyses included query length and the presence of question words. Results were compared between external and internal queries. Results from this study were put in the context of existing literature regarding user search behavior. Analyses demonstrated that external search engines were an important source of traffic to AfterTheInjury.org with 1 in 5 visits driven from the most popular search engines, Google, Yahoo and Bing. Queries were longer than typical queries (AfterTheInjury query averaged 6.27 terms; typical medical query, 2.3-2.4 terms). Nearly 1/4 of queries leading to AfterTheInjury.org took the form of questions: 22.7% of external searches were questions with 10.7% of external
