Summarizing former sessions for user-centric OLAP
Résumé
We propose a framework for summarizing former analyses to assist the user exploring a data cube. In this framework, simple operators are used for automatically summarizing log files consisted of sequences of unevaluated OLAP queries. We provide a simple implementation of the framework for summarizing logs of OLAP queries, and we test it with respect to a query personalization technique based on mining a query log.
