半结构化多Web文本数据挖掘的研究

The research of data mining for multiple semi-structured Web text

在Web文本挖掘过程中,挖掘对象数据量大,且多是半结构化或无结构化的数据。采用了XQuery语言与经典的Apriori算法相结合的方法进行研究,引入了XQuery语言中的函数,实现了对多个Web文档的挖掘,通过具体的实例进行验证,该算法能够提高Web文本挖掘的时间效率。

In the process of Web text mining, mining object is the large amount of data and the data is semi-structured or unstructured. This paper adopts the method of combing classic Apriori algorithm and XQuery language for study, introduces the function in XQuery language, Implementation of the mining of multiple Web documents, verified by the concrete examples. The algorithm can improve the time efficiency of Web text mining.
