A previously proposed keyword search paradigm produces, as a query result, a
ranked list of Object Summaries (OSs). An OS is a tree structure of related
tuples that summarizes all data held in a relational database about a
particular Data Subject (DS). However, some of these OSs are very large in size
and therefore unfriendly to users that initially prefer synoptic information
before proceeding to more comprehensive information about a particular DS. In
this paper, we investigate the effective and efficient retrieval of concise and
informative OSs.
