Leveraging query logs benefits the users analyzing large data warehouses. But so far nothing exists to allow the user to have concise and usable representation of what is in the log. In this paper, the authors propose a framework for summarizing OLAP query logs. This framework is based on the idea that a query can summarize another query and that a log can summarize another log. It includes a simple language to declaratively specify a summary, a measure to assess the quality of a summary and an algorithm for automatically computing a good quality summary of a query log.
