Managing Multiversion Xml Documents with Compressed Delta

Abstract

Today web contains huge amount of information. Important part is to obtain business value from existing information. XML is useful to accomplish features of business functions. Hence to attain those promises it is important to retain those XML documents effectively. Content and structure of Dynamic XML documents changes frequently based on user behavior and produces multiple versions of it. Multiversion XML documents are having huge applicability which demands for their effective organization. Clustering is better solution to retain these documents. But due to dynamic nature of XML documents initially obtained cluster compositions becomes invalid in later stage and traditional methods are not effective to obtain most recent clustering solutions. In this paper we are proposing time efficient technique called Compressed Delta (C∆) in response to obtain most recent clusters of multiversion XML documents. C∆ contains sufficient information to get essential document version with minimum operational cost for future references. Proposed C∆ is comprehensively assessed on several real-life datasets exhibiting extreme characteristics. Experimental results shows that proposed (C∆) to obtain required XML document version outperform the related state-of-the-art approaches.
