| With the development and popularization of the Internet,network data is produced at an explosive growth rate.Large scale,loose structure,and diverse and heterogeneous content are the characteristics of network content,which presents a challenging topic—how to effectively acquire information and knowledge.Knowledge graph is designed to describe the relationship between entities and entities in the objective world.It is a knowledge base that stores knowledge in the form of graphs.With its powerful semantic processing capabilities and open organization capabilities,it provides help for structured storage of knowledge and a large amount of intelligence apps in the Internet.Therefore,this paper combines the knowledge graph with 5G applications,and uses the knowledge graph to build a knowledge network of related articles in the 5G application field to realize the extraction,management,storage and visualization of knowledge,and combines the search function of the graph database to explore the knowledge graph in practice.applications in.This paper systematically sorts out the development process,construction process,methods and technologies of knowledge graph construction,and then defines the nodes and relationships of the information knowledge graph in the 5 G application field according to the characteristics of the articles in the 5G application field and the needs of personnel in related fields.This paper uses the natural language processing technology based on Word2 Vec to train the word vector model on the article data dataset.Combined with the analysis of actual conditions and existing research,the article is classified and extracted by the combination of TF-IDF and DT-CS.Abstract generation.Then use Neo4j to store and visualize the knowledge graph.This paper verifies the feasibility of building an information knowledge graph in the 5G application field through practical operations.Based on the constructed knowledge graph,this paper explores the application of information knowledge graph in research work in the 5G application field from two aspects:information retrieval and information recommendation.This paper constructs a knowledge map of 5G application field information,which provides a reference for the feasibility of knowledge map application in this field.At the same time,the results of this paper provide a reference for relevant researchers,government and relevant regulatory departments,and relevant enterprises,and have certain theoretical and practical significance. |
