Construction and application of knowledge graph of digital measuring tools
The comprehensive and accurate description of the types of digital measuring tools and their associa-tions are helpful for people to deeply understand and select them correctly.For this reason,we explore the con-struction and application of the knowledge graph of digital measuring tools.First,the semi-automatic construc-tion principle of digital gauge ontology is studied,and concepts are extracted by the comprehensive algorithm AR of domain concept extraction,combined with lexical templates,multiple clustering of Jaccard coefficients,SAO structural PPMI,Dice measurement intensity and other algorithms extract conceptual relationships.And then the Protégé tools are used to complete ontology construction.Secondly,a PRGC entity-relation joint extrac-tion model that integrates entity-relationship categories is proposed to extract corpus overlapping triple informa-tion.Finally,on this basis,a prototype system is designed to automatically extract knowledge related to the structure and function of digital gauges from web pages,and construct its knowledge graph semi-supervised;and further provide the visualization and knowledge retrieval functions of the knowledge graph of digital gauges.In this way,the intelligent level of knowledge management of digital display measuring tools is improved.
