对零件本体的异构问题进行讨论。给出零件本体的定义和映射过程模型.提出一种结构——特性本体映射算法采解决零件本体异构问题.该映射算法由结构相似性算法和零件特性相似性算法组合而成。以查全率和查准率为目标,通过实例分析说明该方法的有效性。
Discusses the problem of part heterogeneity, definition of part ontology and mapping process model, presents an ontology mapping algorithm based on structure and characteristics to resolve the heterogeneity problems, the algorithm is a composition of structure similarity algorithm and part characteristics similarity algorithm. Using recall and precision ratios for aims, takes an example to explain the algorithm is validity.
