基于知识图谱的精密传动部件工艺路线推荐模型
A knowledge graph-based model for process routes recommending of precision transmission components
摘要
Abstract
To address the inefficiencies in process route design and the difficulty in reusing knowledge in the machining of preci-sion transmission components,a knowledge graph-based process route recommendation model was proposed for precision transmis-sion components.Firstly,an ontology-based method was used to construct the process knowledge schema layer for precision trans-mission components.Secondly,entity recognition and relation extraction were achieved using the Electra+BiLSTM+CRF model and the BiLSTM+Self-Attention model,respectively,and Damerau-Levenshtein distance was used for knowledge fusion,completing the data layer construction.Then,based on the constructed process knowledge graph,process route recommendations were achieved by combining the similarity of component process units and process route structures.Finally,a process route recommendation system was developed and demonstrated with an example of a specific type of ball screw.Experimental results show that the recommenda-tion accuracy reaches 89.5％,proving the feasibility of the model,which can enhance knowledge reuse and improve process route design efficiency,providing a more scientific and reasonable reference for decision-making.关键词
