Abstract

As a step towards the design of an Inductive Database System, in this paper we present a primitive for constraint-based frequent pattern mining, which represents a careful trade-off between expressiveness and efficiency. Such primitive is a simple mechanism which takes a relational table in input and extracts from it all frequent patterns which satisfy a given set of user-defined constraints. Despite its simplicity, the proposed primitive is expressive enough to deal with a broad range of interesting constraint-based frequent pattern queries,using a comprehensive repertoire of constraints defined over SQL aggregates. Thanks to its simplicity, the proposed primitive is amenable to be smoothly embedded in a variety of data mining query languages and be efficiently executed, by the state-of-the-art optimization techniques based on pushing the various form of constraints by means of data reduction.
