Abstract: An optimization-based framework is utilized to extract broad query aspects from query reformulations performed by users in historical user session logs. Objective functions are optimized to yield query aspects. At run-time, the best broad but unspecified query aspects relevant to any user query are presented along with the results of the run time query.

Abstract translation: 利用基于优化的框架从历史用户会话日志中的用户执行的查询重新设计中提取广泛的查询方面。 优化目标函数以产生查询方面。 在运行时，与任何用户查询相关的最佳广泛但未指定的查询方面与运行时查询的结果一起显示。
