The article substantiates the timeliness of discussing this issue and describes the classes of problems that can be solved using hierarchical graph models. It discusses the structure of particular hierarchical graph models, their layers, and how it is possible to connect these models layer by layer and create a single hierarchical graph model. It also discusses data formats and approaches to adding dynamic data that are applicable to the resulting hierarchical knowledge graph. It studies the advantages of the hierarchical knowledge graph over one-level analogs. To explain the advantages of using a hierarchical knowledge graph, an example of modeling such a knowledge graph for a cable TV operator’s network is given and compared with a one-level knowledge graph using a specific problem encountered by the operator. It is shown that it is much less difficult to execute queries of the same kind using a hierarchical graph. At the end of the article, conclusions are made and directions for future research are discussed.","PeriodicalId":177075,"journal":{"name":"PROBLEMS OF ENGINEERING CYBERNETICS AND ROBOTICS","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130258594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presented review deals with current research situation, makes analysis and classification of publications on the topic with regards to scientific, temporal, geographic, etc. aspects in order to determine promising development trends. Publication base Scopus serves as a source for sampling. Analysis and sampling was implemented both in the manual mode and by means of special software for automated search by keywords. Sample could be considered as a representative one: about 2000 publications from more than 1000 sources. Network security research statistical characteristic obtained as a result of analysis were visualized in a graphic form by diagrams of different types. Statistics were represented according to different criteria: problem statement, application domain, publication activity in different continents, countries, attribution to authors, research and industrial organizations, publisher houses, citation index, temporal research activities distribution in the period of 2015-2020 years, etc. Analysis resulted in formation of most relevant set of works, on the basis of which classifications of promising research directions and network security assurance methods were developed.","PeriodicalId":177075,"journal":{"name":"PROBLEMS OF ENGINEERING CYBERNETICS AND ROBOTICS","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125661544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
