AI总结:

该研究将专利中的工程设计知识构建为知识图谱,通过分析其语言学与结构特征,提炼出通用句法与子图模式,为设计知识构建及大语言模型的设计知识表达提供指导。

摘要:

自然语言人工制品描述是工程设计知识的主要载体,其检索、表示与重用是支撑设计过程中知识密集型任务的基础。本文将专利人工制品描述中的设计知识阐释为知识图谱,并对其进行研究以理解语言学与结构基础。本研究的目的是推进设计知识的传统视角与本体论视角,并指导大语言模型(Large-Language Models, LLMs)如何生成能反映设计环境中有价值知识的自然语言响应。我们从按技术类别分层抽样的专利样本中构建了33881个知识图谱。在语言学基础方面,我们对唯一实体和关系的频率进行了Zipf分布分析,分别识别出64种和37种可推广的语言句法。这些关系主要代表属性('of')、结构('in'、'with')、目的('to'、'for')、层级('include')、例证('such as')和行为('to'、'from')。在结构基础方面,我们从生物/生态网络的各类研究中汲取灵感,从专利知识图谱中发现了模体。我们识别出4种三节点和4种四节点子图模式,这些模式可收敛并简化为序列[->...->]、聚合[->...<-]和层级[<-...->]。基于这些结果,我们提出了实体与关系的具体化策略以及层级结构的阐释策略,这可能有助于设计知识的构建与模块化。

英文摘要:

Natural language artefact descriptions are primary carriers of engineering design knowledge, whose retrieval, representation, and reuse are fundamental to supporting knowledge-intensive tasks in the design process. In this paper, we explicate design knowledge from patented artefact descriptions as knowledge graphs and examine these to understand the linguistic and structural basis. The purpose of our work is to advance the traditional and ontological perspectives of design knowledge and to guide Large-Language Models (LLMs) on how to articulate natural language responses that reflect knowledge that is valuable in a design environment. We populate 33,881 knowledge graphs from a sample of patents stratified according to technology classes. For linguistic basis, we conduct Zipf distribution analyses on the frequencies of unique entities and relationships to identify 64 and 37 generalisable linguistic syntaxes respectively. The relationships largely represent attributes ('of'), structure ('in', 'with'), purpose ('to', 'for'), hierarchy ('include'), exemplification ('such as'), and behaviour ('to', 'from'). For structural basis, we draw inspiration from various studies on biological/ecological networks and discover motifs from patent knowledge graphs. We identify four 3-node and four 4-node subgraph patterns that could be converged and simplified into sequence [->...->], aggregation [->...<-], and hierarchy [<-...->]. Based on these results, we suggest concretisation strategies for entities and relationships and explicating hierarchical structures, potentially aiding the construction and modularisation of design knowledge.
