This article mainly researches mining questions of association rules in temporal data. A fundamental structure for double association rules mining is proposed, based on temporal dataset, to define the main notion used in temporal knowledge discovery in a formal way. The relevant properties of the notion are proved. A data structure, hash table based on the double linked list will be used for the storage...
Quotient cube is a summary structure for a data cube that preserves its semantics. The iceberg cubing problem is to compute the multidimensional group-by partitions that satisfy given aggregation constraints. As we know, there has been no algorithm that computes iceberg quotient cube for nonantimonotone aggregate functions. In this paper, we propose a new structure hyper-star-tree and an efficient...
