Towards an Analytics Query Engine

This vision paper presents new challenges and opportuni- ties in the area of distributed data analytics, at the core of which are data mining and machine learning. Atrst, we provide an overview of the current state of the art in the area and then analyse two aspects of data analytics systems, se- mantics and optimization. We argue that these aspects will emerge as important issues for the data management com- munity in the next years and propose promising research directions for solving them.
