Log Data Analysis on Interactive Information Access

Abstract

The characteristics of user behaviors in explorative information access are reported, which reflect the differences of the environments she uses and the tasks she engages in. Using a model of information access behaviors and a log data coding based on that model, the analysis was conducted on the log data obtained in VisEx, an experiment for evaluating interactive and explorative information access environments. It shows that introduced retrieval methods, narrowing-down and similarity-based retrieval, are used as a substitute of sequential document checking, and those effectiveness differs depending on task characteristics.
