摘要
设计理性重用的主要步骤在于理性模型的检索,然而目前设计理性模型检索的结果以单独的理性元素节点或完整实例的形式呈现,结构过于简单或复杂,不易于设计者理解和重用。针对以上问题,提出基于语义的设计理性片段提取方法。在关键词检索的基础上,对关键词检索得到的结果节点进行语义推理,得到包含结果节点的核心最小设计理性片段,通过对最小理性片段进行聚合与片段重复合并完成片段提取。基于设计理性片段的提取,为设计者提供满足检索需求且能完整表达某一设计过程的理性知识片段,形成以设计理性片段为基本单元的检索与重用模式。通过实例验证了片段提取方法和片段重用的有效性。
The existing retrieval results of Design Rationale （DR） model are presented in isolated rational dements node or complete cases, which lead to the structure too simple or too complex to understand and reuse To solve the above problems a semantic-based DR segment extraction method was proposed. Based on the existing keyword-based DR retrieval method, the Minimum-Length DR Segment （MLS） was obtained by semantic reasoning of retrieved DR elements. Through the clustering MLS and merging segment repeatedly, the segment was extracted. Based on segment extraction, a new reuse pattern based on DR segment was formed through providing DR segment for designers. An application example was demonstrated to verify the feasible of extraction method and the effectiveness of extracted segment
