Abstract

Background/Objective: With more ways and platforms for people's voices, timely guidance and proper handling of public opinion are increasingly important for social development. Methods/Statistical analysis: To investigate the current status of research on public opinion control and emergency response, the article uses the web of science database as the research object and analyzes the collected literature for co-citation network and keyword co-occurrence network with the help of citespace software, and constructs a knowledge graph. Findings: Research on public opinion control and emergency response shows both concentrated and decentralized development in terms of publishing journals and countries/regions, with the United States, the United Kingdom, and China as the main countries. Research hotspots in recent years are mainly in social media, law, and emergencies, which is a research involving multidisciplinary fields. Improvement/Application: Public opinion control and emergency response have more research space in social media, legal protection, and emergency events.
