Activity logs allow to study the usage of search engines and to better adapt them to the needs of their users. The study of multilingual log analysis was promoted by the Cross Language Evaluation Forum (CLEF). For the second time, the track LogCLEF was conducted. As is 2009, large log files were obtained from information providers. One log covers 30 months of activities on the website of The European Library (TEL) and the second log shows user activities of users on the German EduServer. Seven groups explored the data using a variety of approaches They analyzed language of queries, activities within sessions and success of searches. The data for the track, the evaluation methodology and results are presented and discussed.Pubblicazioni consigliate
