An intelligence strategy of refactoring XML structure based on XFP-tree
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 2
Abstract
Because the query rate based on the XML documents is unable to fulfill the daily increasing demands of the information association and the multiformity of service request, this paper proposed a new frequent pattern tree algorithm for selected incremental vector items set of refactoring XML structure (XFP-tree). The algorithm bases on the XML key, firstly deals XML structure with vector matrix processing, then uses project frequent pattern tree to optimize the XML structure by dissociating, uniting, updating and canceling etc. in order to satisfy the conciseness of the XML structure and query multiformity. Combining project and tree-structure manipulation, it discusses the divide rule of XML key vector matrix frequent pattern. And it improves the algorithm efficiency by establishing heuristic strategy and support thresholds. Contrasted with other association rule’s algorithms, a series of emulation experiments show that this method which has proper the effectiveness and feasibility is an efficacious method of refactoring XML structure.
