Komprese XML souborů

Abstract

Working with XML files is now becoming more frequent. There are XML documents containing large amount of data. This thesis deals with existing algorithms used for XML compression and some new ways of improving current approaches. This thesis focuses on some popular text compression algorithms and their application either in standard text file compression or in XML compression through semantic information that is present in XML documents. The thesis also describes extending the methods with XML optimization through agglomerative clustering. Various compression methods are compared on the basis of testing in order to find out whether XML compression methods extension can achieve better results.
