关于属性组合计数的信息是数据集分析的核心。它可能揭示偏见;它可以帮助确定使用的适合性。虽然单个属性值的计数可以存储在一些数据集简档中,但是存在太多的属性组合,因此存储每个组合的计数是不实际的。为此,我们提出了存储一个有限大小的“标签”的概念,可以用来获得这些计数的良好估计。标签包含有关数据中所选模式(属性值组合)的计数的信息。我们定义了一个估计函数,它使用这个标签来估计每个模式的计数。直觉上,在标签大小和其估计误差之间存在折衷。我们提出了一个示范的计数,一个系统,允许用户检查这种权衡以及标签的计数信息。我们将使用真实数据证明Countata的有用性,并说明我们的估计范式的有效性。
Information regarding the counts of attributes combination is central to the profiling of a data set. It may reveal bias; it can help determine fitness for use. While counts of individual attribute values may be stored in some data set profiles, there are too many combinations of attributes for it to be practical to store counts for each combination. To this end, we present the notion of storing a "label" of limited size that can be used to obtain good estimates for these counts. A label contains information regarding the count of selected patterns-attributes values combinations-in the data. We define an estimation function, that uses this label to estimate the count of every pattern. Intuitively, there is a trade-off between the label size and its estimation error. We propose a demonstration of Countata, a system that allows the user to examine this trade-off as well as the label's count information. We will demonstrate the usefulness of Countata using real-life data, and illustrate the effectiveness of our estimation paradigm.
