摘　　要：针对本体映射中各种策略不能依据本体间的差异进行不同映射处理以及多策略结合时权值分配不合理的问题,提出一种本体映射方法。该方法对各种映射策略根据当前映射任务的特点进行自适应处理,在映射过程中对不同策略的可信度做自适应计算,依据可信度进行多策略结合,得到最终的映射结果。实验结果表明,该方法在保证通用性和稳定性的同时,能提高映射的查准率。Aiming at the problems of many strategies can not do different operations on ontology mapping according to the differences existed in ontology and they are distributed the irrational weights when integrating each strategy, this paper proposes a new ontology mapping method. In this method, different mapping strategies do different process according to the character of mapping task, and the credibility of different strategies is computed in the process of mapping, the different strategies are assembled by the credibility, get the final mapping results. Experimental results show that this method can improve the recall and precision of ontology mapping while maintaining currency and stability.
