There might be the same information has been describe in various ways. When user wants to search some information from XML documents, user might not retrieve all related results because of the difference of elements (tag names). To retrieve all related results,...
Duplicate detection, which is an important subtask of data cleaning, is the task of identifying multiple representations of a same real-world object and necessary to improve data quality. Numerous approaches both for relational and XML data exist. As XML becomes increasingly popular for data exchange and data publishing on the Web, algorithms to detect duplicates in XML documents are required. Previous...
A Web information extraction system based on label library is proposed for extracting information from data intensive Web pages in this paper. It downloads dynamic Web pages based on a knowledge database, changes them to XML documents after a preprocessing, mines data regions by using MDR repeated patterns discovery algorithm, recognizes their structure and extracts data from them through a novel...
XML has become the standard for data representation on the web. This expansion in reputation has prompted the need for a technique to access XML documents. Many techniques have been proposed to tackle the problem of mining XML data. We study the various techniques to mine XML data and yet We presented a java based implementation of FLEX algorithm for mining XML data.
