摘要和多样化的查询结果的方法，近年来引起了极大的关注，因为它们有助于提供查询结果与大量的元组，以更丰富的信息的方式给用户。我们提出了QAGView（快速聚合视图），它提供了一个全面的概述高价值的聚合查询答案的形式总结（显示高层次的属性，出现从子集的答案）与覆盖保证（对于用户指定的数量的最高值的答案），这是多样的（避免重叠或类似的摘要）和相关的（侧重于高价值的聚合答案）。QAGView允许用户将高级摘要视为集群，并为其组成结果元组扩展各个集群。用户可以根据自己的偏好指定一些参数来微调QAGView的行为。为了帮助用户以交互方式选择适当的参数，QAGView采用了一套优化，可以快速预览摘要质量在各种参数设置下的变化，以及实时可视化摘要如何响应参数更新。
Methods for summarizing and diversifying query results have drawn significant attention recently, because they help present query results with lots of tuples to users in more informative ways. We present QAGView (Quick AGgregate View), which provides a holistic overview of high-valued aggregate query answers to the user in the form of summaries (showing high-level properties that emerge from subsets of answers) with coverage guarantee (for a user-specified number of top-valued answers) that is both diverse (avoiding overlapping or similar summaries) and relevant (focusing on high-valued aggregate answers). QAGView allows users to view the high-level summaries as clusters, and to expand individual clusters for their constituent result tuples. Users can fine-tune the behavior of QAGView by specifying a number of parameters according their preference. To help users choose appropriate parameters interactively, QAGView employ a suite of optimizations that enable quick preview of how the quality of the summaries changes over wide ranges of parameter settings, as well as real-time visualization of how the summaries evolve in response to parameter updates.
