英文摘要
Keyword search has been recently extended to relational databases to retrieve information from text-rich attributes. However, all the existing methods focus on finding individual tuples matching a set of query keywords from one table or the join of multiple tables. In this project, we will systematically investigate a novel theme of aggregate keyword search: finding minimal group-bys covering a set of query keywords well, which is useful in many applications.
