基于本体的产品设计知识表达

产品设计知识包含结构化知识如单一的工程数据库等;半结构化知识如Web页面等;非结构化知识如普通文档等。因此实现这些知识的逻辑表达是研究产品设计知识库的关键,而知识的共享与重用是构建知识库的重要目标。基于此本文提出了一种基于本体的知识表达方法,把产品设计视为一个领域本体,从而确定其知识分类并提取类间的关联属性,最后使用XML技术完成了设计知识的本体建模,为构建可重构的产品设计知识库提供了理论支持。

Ontology-based Knowledge Representation of Product-design

The product-design knowledge includes structural knowledge such as single engineering data-base, semi-structural knowledge like web page, and nonstructural knowledge as normal document. So realizing logic representation of knowledge is a key to studying product-design knowledge-base. And the share and recycle of knowledge is an important goal to build knowledge-base. So we bring out a knowledge representation method based on ontology, regarding product-design as ontology, classifying those knowledge correctly , and founding out the correlative property among knowledge-class. Then we build the ontology-model of designing knowledge u-sing XML and provide theoretical support for constructing reconfigurable product-design knowledge-base.
