Beyond roll-up’s and drill-down’s: An intentional analytics model to reinvent OLAP
作者：
Highlights：
• We propose a new model for OLAP, which we call the Intentional Analytics Model.
• Its operators (describe, assess, explain, predict, suggest) address user intentions.
• We redefine what a query answer is: not just tuples, but also models and highlights.
• Models (results of mining algorithms) are uniformly modeled a data-to-model mapping.
• We introduce a novel method for assessing the surprise of a new query result.
