(English Abstract)
Recently, the needs for effective real-time change detection algorithms for XML/HTML documents are increased in such fields as the detection of defacement attacks to web documents, the version management, and so on. Especially, those applications of real-time change
detection for large number of XML/HTML documents require
fast heuristic algorithms to be used in real-time
environment, instead of algorithms which compute minimal cost-edit scripts. Existing heuristic algorithms are fast in execution time, but do not provide satisfactory
edit script. In this paper, we present existing algorithms
XyDiff and X-tree Diff, analyze their problems and propose
algorithm X-tree Diff which improve problems in existing ones. X-tree Diff has similar performance in execution time with existing algorithms, but it improves matching ratio between nodes from two documents by refining
matching process based on the notion of efficiency of
matching.
