Knowledge Discovery in Database and Its Application in Clinical Diagnosis

目前海量的数据存储已经远远超过了人的理解能力 ,尤其是现代医学数据量越来越大 ,而传统的统计技术及数据管理工具已经力不从心 ,知识发现及数据挖掘工具在处理海量数据库时显示了它们的长处。本文首先介绍了知识发现及数据挖掘的概念 ,又详细介绍了知识发现的一个重要工具粗糙集理论的有关基础知识并举例介绍了其应用。

Nowadays the tremendous amount of data has far exceeded our human ability for comprehension,and this has been particularly true for the madical database. However,traditional statistical techniques are no longer adequate for analyzing this vast collection of data. Knowledge discovery in database and data mining play an important role in analyzing data and uncovering important data patterns. This paper briefly presents the concepts of knowledge discovery in database and data mining,then describes the rough set theory,and gives some examples based on rough set.
