摘要
在产品设计过程中缺少设计规范技术文档的知识化表征和可视化手段,导致设计师对设计规范技术文档的知识提取效率受限。针对工程领域产品设计这一复杂的知识密集型过程应遵循的规则规范,提出一种面向工程领域中文技术规范文本的知识提取与知识图谱构建方法。本方法根据设计规范文本的特点,对文本进行分类实体提取及实体关系提取,设计中文设计规范技术文档知识提取算法,能够准确提取列举说明、条件规则、比较关系、解释说明4类知识。设计面向Neo4j的知识图谱构建算法,以实现设计规范知识的可视化表达。同时,在知识提取的基础上,可以通过对中文技术文档的处理进一步扩充对应知识库。使得在产品设计过程中更易满足设计师的特定需求,为产品设计工作提供便利。
The lack of knowledge-based representation and visualization methods for design specification technical documents in the product design process limits the efficiency of designers in extracting knowledge from design specification technical documents.A knowledge extraction and knowledge graph construction method for Chinese technical specification texts in the engineering field is proposed to address the rules and specifications that should be followed in the complex knowledge intensive process of product design.This method classifies entities and extracts entity relationships based on the characteristics of design specification texts.It designs a knowledge extraction algorithm for Chinese design specification technical documents,which can accurately extract four types of knowledge:enumeration,conditional rules,comparative relationships,and explanatory explanations.A knowledge graph construction algorithm is designed for Neo4j to achieve visual representation of design specification knowledge.Meanwhile,on the basis of knowledge extraction,the corresponding knowledge base can be further expanded by processing Chinese technical documents.The proposed method makes it easier to meet the specific needs of designers in the product design process,providing convenience for product design work.
