| 摘 要： | 传统的基于关键字的搜索方法无法很好地在"模具知识管理系统"中检索到相关的设计标准。通过分析注塑模具本体的语义相关性的特点,本文提出了一种计算注塑模具本体的概念相关度的方法及其实现算法,并对注塑模具本体中的部分概念进行了概念相关度的计算和分析。结果表明,所提出的计算方法能够有效地为基于注塑模具本体概念的相关信息语义检索及其检索结果的排序提供量化的依据。

| Abstract: | Traditional searching method based on key words cannot very well find related design standards in the mould knowledge management system.According to the characteristics of semantic relativity of injection mould ontology,we propose a method for calculating the conceptual relatedness of injection mould ontology and its implementing algorithm.We calculate and analyze the conceptual relatedness of some concepts in the injection mould ontology.The result shows that the proposed method provides the efficient quantization criterions for conceptual relevance information semantic retrieval and its result ranking based on injection mould ontology. |
