大数据时代电子政务中XML文档相似性
Similarity of XML Documents in E-government in Era of Big Data
摘要
Abstract
XML has been widely studied as the standard of data exchange in e-government applications. With the arrival of the era of big data,the management of XML data in e-government is also becoming more and more important. In the management of XML data,the similarity of XML documents is the key of XML data integration and XML data classification. In order to study the XML document simi-larity,the XML document are transformed into tree,extracting the corresponding characteristics of the nodes of the tree,and then using these characteristics to calculate the similarity of nodes,and then the final node similarity can be obtained by the ELM( Extreme Learning Machine) algorithm. Based on the similarity of nodes,the algorithm of similarity comparison of the XML document tree is given,which can obtain the similarity of XML documents. Based on the given specific evaluation indexes,the accuracy,recall, F-measure values and the corresponding time are obtained through experiments in two different data sets using the method proposed. The performance advanta-ges of the proposed method are verified by experiments.关键词
