Using the recent \u201cG20 Summit\u201d as a case study, this study employs a mixed-methods approach that incorporates both deductive and inductive reasoning. Social network analysis (SNA) and graph theory are used to evaluate specific social relationships in the context of the G20 summit, while a combination of structured and content (semantic) analysis is performed. The findings indicate that individual power is becoming increasingly important in the age of online news media. Individuals contribute significantly to the diffusion of information and may play a decisive role in the future. The study also finds that the frequency of retweets increases as the reciprocity ratio increases, and mentions may be the most effective method for delivering political news on online news media platforms. Practical implications suggest strategies for managing information diffusion effectively. Additionally, this study provides insights into effective information diffusion on online news media platforms that can be utilized in health communication management during the COVID-19 era. This study expands theoretical understanding by investigating the role of individual power in the age of online news media and enriching the literature on online news media through the use of structured and content analysis based on social network analysis.<\/jats:p>","DOI":"10.3390\/systems11060290","type":"journal-article","created":{"date-parts":[[2023,6,6]],"date-time":"2023-06-06T01:38:26Z","timestamp":1686015506000},"page":"290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Online News Media Analysis on Information Management of \u201cG20 Summit\u201d Based on Social Network Analysis"],"prefix":"10.3390","volume":"11","author":[{"given":"Xiaohong","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Economics and Management, Beijing Institute of Petrochemical Technology, Beijing 102617, China"},{"name":"Enterprise Development and Management Innovation Research Center, Development Research Centre of Beijing New Modern Industrial Area, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuting","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Economics and Management, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanbo","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Media and Communication, City University of Hong Kong, Hong Kong SAR 999077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2484-6751","authenticated-orcid":false,"given":"Cheng","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Strategic Management and Organisations International Business School Suzhou Xi\u2019an Jiaotong, Xi\u2019an Jiaotong-Liverpool University, Suzhou 215123, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanqi","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Economics and Management, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,5]]},"reference":[{"key":"ref_1","first-page":"36","article-title":"The machinery of hope","volume":"1048","author":"Dickinson","year":"2008","journal-title":"Roll.
