相对简单的转换可以大大加快数据挖掘查询的执行速度。虽然一些ILP系统使用这样的转换，但对它们或它们如何相互关联知之甚少。本文介绍了一些这样的转换。并非所有这些都是新的，但没有研究比较它们的功效。该文件的主要贡献是：（a）澄清了各种转变之间的关系;（B）对应用这些转变可以获得什么进行了实证研究;（c）就可能受益于这些转变的各类问题提供了一些指导。
Relatively simple transformations can speed up the execution of queries for data mining considerably. While some ILP systems use such transformations, relatively little is known about them or how they relate to each other. This paper describes a number of such transformations. Not all of them are novel, but there have been no studies comparing their efficacy. The main contributions of the paper are: (a) it clarifies the relationship between the transformations; (b) it contains an empirical study of what can be gained by applying the transformations; and (c) it provides some guidance on the kinds of problems that are likely to benefit from the transformations.
