对数据挖掘技术的探讨

Discussion of Data Mining

进入信息社会以来，各类数据、信息急剧地增长，具有海量、冗余的性质，这时人们开始考虑：如何才能不被信息淹没，并且能从中及时发现有用的知识，以提高信息的利用率，而这个任务就落在数据挖掘的身上。数据中蕴涵着知识．数据挖掘正是从大量数据中提取或“挖掘”知识，从而实现从“数据→信息→知识”的过程，为各信息技术领域的发展提供强大的支持。在下文中，将对数据挖掘这种技术进行讨论．

The high speed development of information technology, the data which the people accumulate grows suddenly, moreover the analysis result of data lacks the reliability ,and the efficiency of data processing becomes lower, it is important that extract the valuable knowledge from an amount of data. The data mining is one kind of data processing technology and is a vital step of knowledge discovery in database.
