摘要
随着大量的XML数据的出现,给数据挖掘领域提出了新的挑战。传统数据挖掘是基于关系数据库和数据仓库的,如何挖掘出XML形式的数据成为研究的热点问题。由于XML文档是一种半结构化数据,使用传统的数据挖掘方法对XML数据进行挖掘是不适用的。提出了一种基于粗糙集理论的XML挖掘模型,并进行了实验,结果表明利用粗糙集理论对XML数据挖掘是可行的。
With the emergence of of XML data,the field of data mining raise new challenges.Traditional data mining is based on relational database and data warehouse,how to dig out the data as XML is a hot issue.The XML document is a semi-structured data,the traditional method of XML data mining data mining is not applicable.A rough set theory is proposed based on XML mining model,and experimental results show that rough set theory using XML data mining is feasible.
