摘要
数据库中的知识发现即数据挖掘是致力于大型数据分析中的半自动工具的研究。讨论了数据挖掘中一些常用的方法 ,特别是频繁发生模式中层次搜索及其在不同领域中的应用。讨论了数据挖掘查询编译成算法的可能性 ,并列举了数据挖掘及知识发现中现存的一些问题。
Knowledge discovery in databases and data mining aim at semiautomatic tools for analysis of large data sets. We consider some methods used in data mining, concentrating on levelwise search for all frequently occurring patterns. We show how this technique can be used in various applications. We also discuss the possibilities for compiling data mining queries into algorithms, and look at the use of sampling in data mining. At the end, we list several research problems in data mining and knowledge discovery.
