Design of a File Format for Logging Website Interaction



John V. Cugini, Sharon J. Laskowski


The logging of user behavior in support of Web usability testing is constrained by the difficulty of capturing and analyzing large amounts of logged data. However, there is great potential for the development of tools to support automated recording and analysis, especially for remote or large scale testing. In this paper, we propose a format for the representation of user interaction with a Website. A widely accepted format enables the development of a set of software tools to process the data, the sharing of data sets for longer term analysis and research, and provides a common language for expressing user interaction with a Website.
