Search Path Visualization and Session Performance Evaluation with Log Files

Our approach to the Log Analysis for Digital Societies (LADS) task of LogCLEF 2009 is to define three different levels of performance: success, failure and strong failure. To investigate the log files we adopt qualitative and quantitative methods. In a more qualitative approach we attempt to identify intercultural differences in user patterns by visualizing the user interactions with The European Library (TEL). On the quantitative level we calculate the relative frequencies of the different performance levels in relation with several aspects e.g. whether a user used the advanced search option or not.
