Automatic Facet Construction For SubDataspaces


After a unique sub-dataspace DS’ has been
identified by the user, the system dynamically
constructs a multi-faceted search (MFS) interface for
the user to explore detailed level aggregation in DS’.
In real world databases, the number of dimensions
may be large. And each dimension may have many
attributes.

So, need to rank group-by attributes dynamically based on
interestingness of the resulting partitions.
