Research On Construction Of Knowledge Map In Steel Structure

As the knowledge graph has been better applied in many fields,as a new knowledge research point,it has strong practicality in the field of knowledge management and semantics,and has attracted the attention of many scholars.The field of steel structure,as a highly intersecting field,has the characteristics of large amount of knowledge,wide range of knowledge,and complicated knowledge structure.With the rapid development of steel structures in China,in the face of massive knowledge,a scientific and effective management method is urgently needed.Knowledge graph as an auxiliary knowledge base can realize the true value of information in acquiring information and interpreting semantics.In view of the fact that knowledge graphs have been well developed in other fields,this article will refer to the existing knowledge graph construction methods and use the steel structure field as a research background to construct the knowledge graph in the steel structure field.The thesis focuses on the construction of knowledge graph in the field of steel structure.First,through the analysis of the field and knowledge of steel structure,we understand its field and knowledge characteristics.Then,in view of the problems in knowledge management in the field of steel structure,combined with the construction method of mainstream knowledge graph,the knowledge graph construction method in line with the field of steel structure was improved and designed.The construction of knowledge graphs in the specific steel structure field starts with the data layer and the pattern layer.The data layer uses the python crawler to obtain knowledge,and the Bi LSTM-CRF model performs entity extraction and cosine similarity calculation to test the relationship between entity relationships.Fusion effect and quality;the construction of the model layer is based on the ontology theory,and the relationship between entities is obtained by defining concept classes and attributes;finally,Protégé software is used to realize the visualization of the knowledge graph,and the knowledge query function shows the automatic interconnection of knowledge in the field of steel structure And semantic reasoning.The construction of knowledge graph in the field of steel structure makes the expression of knowledge in the field of steel structure simple and clear,enhances the interconnectivity and sharing of knowledge,and knowledge is effectively stored and managed.This article provides a reference for solving the problems of difficult expression,precipitation,sharing,and imperfect knowledge management system in the field of steel structure.It provides value for other scholars to study knowledge management in the steel structure industry in the future,and realizes the steel through the construction of knowledge graph.Visualization and knowledge query of some knowledge in structural industry.
