摘　　要：现有的大规模本体分块与映射系统中大多采用基于参考点的块映射策略,映射策略比较单一,块映射质量不高。因此,提出一种新的基于本体块结构的块映射策略,通过重建本体块结构图来获取块与块之间在结构上的相似度,并将其和基于参考点的策略相结合,通过加权求和得到总的相似度。理论分析和实验结果表明,本文的方法块映射准确率高。The existing large-scale ontologies partitioning and mapping systems mainly use the anchor based block mapping strategy,the mapping strategy is not very diverse,so the mapping quality is not always very high.Therefore,a new block mapping strategy based on the ontology block structure is proposed,which obtain the structure similarity between blocks form each ontology through rebuilding the structure graph of ontology block,and then combine with anchor based strategy to obtain the total similarity by weight sum of the two strategies.Theoretical analysis and experimental results show that this method has a high mapping accuracy.
