| Abstract: | An approach for calculating the structural similarity between XML documents is proposed in this paper. The structural information of an XML document is captured with a structural summary tree (SST). By encoding elements as digital numbers, a SST is transformed to a digit-labeled tree. Digital numbers at different tree levels are concatenated to form a vector after the normalization process. Consequently, each XML document is represented as an m-dimension vector. The GA-based clustering algorithm is adopted since it is able to provide good results irrespective of the starting configuration. Experimental results show the effectiveness and scalability of the approach. |
