| 摘要: |
| 针对BOM概念模型重用的问题，提出了概念模型相似度用于描述两个概念模型之间的相似程度。并提出相似度评估算法用于计算概念模型之间的相似度。根据概念模型的定义，将相似度的计算归结为名字相似度计算和最优匹配计算两个基本过程。研究了算法中接口权重参数和行为权重参数的不同组合对算法查准率和查全率的影响。通过对JC3IEDM数据模型的测试，表明相似度能够正确反映概念模型的组成元素和结构的相似程度，算法可以正确计算出概念模型之间的相似度。算法在保证100%查全率的基础上，查准率大于75%。 |

| Abstract: |
| Base Object Model (BOM) is a modeling standard for facilitating model composition and reuse. For the problem of conceptual model reuse, similarity between two conceptual models was presented to describe their similar degree. A similarity evaluation algorithm for computing the similarity between two conceptual models was also presented. According to the definition of conceptual model, similarity evaluation of algorithm was induced into two basis processes: name similarity computing and optimization matching computing. How different combinations of interface weighted parameter and behavior weighted parameter of the algorithm to affect the precision and recall was also studied. JC3IEDM was applied as benchmark to evaluate the algorithm. The result reveals that the similar degree of elements and structure between two conceptual models can be represented by their similarity collect. Similarity between two models can be computed by the algorithm. When the recall of algorithm is 100%, the precision is greater than 75%. |
