OLAP query suggestion and discovery driven analysis
Abstract
Interactive analysis of datacube, in which a user navigates a cube
with a sequence of queries to find and understand unexpected data, is often tedious.
To better support this process, we propose in this paper to connect two
techniques proposed earlier in this domain. These techniques are, on the one
hand, discovery driven analysis, that guides the user towards regions of the cube
they will find of interest, and on the other hand, query recommendation, that
takes advantage of what the other users did during former analyses. Benefiting
from these techniques we propose a framework for recommending OLAP
queries to the user by taking into account what previous users found of interest
and the explanation they worked out.
