Abstract: In the process of information system conceptual modeling, it is necessary to merge or reuse the existing concept models, to build a complex model to describe the physical world more accurately. Conceptual models similarity computation is an important base of merging, mapping and reusing conceptual models. This paper introduces a method of system similarity computation in the cognitive science, and transforms conceptual model similarity computation into a synthetic computation of the similarity of relationship, binding, entity classes and roles. Experimental results show that this computing method takes into account various relevant factors, the results are more reliable.

Key words: conceptual model, semantic, Unified Modeling Language(UML), cognitive science, similarity

摘要: 在信息系统概念建模过程中,常常需要合并或重用已有模型形成复杂的模型,以更加精确地刻画物理世界模型,而概念模型间的相似度计算是实现这一目标的重要基础。通过引入LISA认知模型的系统相似性计算方法,将概念模型间相似度计算转化为关系,绑定,实体类和角色间相似度的综合计算。实验结果表明,这种计算方法综合考虑了各种相关因素,所得出的结果具有较高的可信度。
