Techniques for semantic weighting and decomposition of XML schemas are investigated in this work for their efficient management. Two approaches are proposed to calculate the weights of XML elements. The first one is based on the analysis of links and their attributes while the other one is based on the information propagated from all reachable nodes. We analyze the influence of different types of links on the weights of XML elements. The weights of XML elements are then used to decompose an XML schema and to choose representatives of decomposed clusters. These two methods provide consistent results. The decomposition of an XML schema can be conducted via two methods: the repetition-based decomposition and the weight-based decomposition. It is shown that the weight-based solution can achieve a multi-resolution decomposition result.
