类比设计(DBA)是一种重要的创新方法，由于其成功和新颖的设计解决方案的历史而备受关注。该方法使用现有设计解决方案的存储库，设计师可以在其中识别和检索类比灵感。然而，对设计师来说，探索类比灵感一直是一项艰巨的任务。这项工作提出了一种由一种称为非负矩阵分解(NMF)的主题建模技术驱动的计算方法。NMF因其能够根据文档的语义内容发现文档中的主题而被广泛应用于文本挖掘领域。在所提出的方法中，迭代地执行NMF来构建设计解决方案的分层存储库，设计者可以使用该存储库来探索类比刺激簇。这种方法已经应用于与机械设计相关的专利库，经过处理后只包含基于组件、行为或材料的内容，以测试是否可以从专利数据的不同表示中发现独特和有价值的基于属性的类比灵感。分层知识库已经可视化，并进行了案例研究，以检验所提出的方法的类比检索过程的有效性。总体而言，本文论证了基于探索的计算方法可以为设计人员提供对设计知识库的增强控制，以检索DBA实践的类比灵感。
Design-by-analogy (DbA) is an important method for innovation that has gained much attention due to its history of leading to successful and novel design solutions. The method uses a repository of existing design solutions where designers can recognize and retrieve analogical inspirations. Yet, exploring for analogical inspiration has been a laborious task for designers. This work presents a computational methodology that is driven by a topic modeling technique called non-negative matrix factorization (NMF). NMF is widely used in the text mining field for its ability to discover topics within documents based on their semantic content. In the proposed methodology, NMF is performed iteratively to build hierarchical repositories of design solutions, with which designers can explore clusters of analogical stimuli. This methodology has been applied to a repository of mechanical design-related patents, processed to contain only component-, behavior-, or material-based content to test if unique and valuable attribute-based analogical inspiration can be discovered from the different representations of patent data. The hierarchical repositories have been visualized, and a case study has been conducted to test the effectiveness of the analogical retrieval process of the proposed methodology. Overall, this paper demonstrates that the exploration-based computational methodology may provide designers an enhanced control over design repositories to retrieve analogical inspiration for DbA practice.
