| Abstract: | This paper proposes an algorithm for intelligent extending to efficiently deriving XML keys based on XML document.The self-contained key set is obtained by utilizing LabelKey file defined before,and the file is dynamically updated at the same time.Theoretical analysis and experiment show the algorithm has a quite high validity of deriving key set,and the superiority is very obvious to the cosmically XML data samples. |
