A bibliometric analysis of research trends for missing persons globally and in East Asia from 2000 to 2021.

A bibliometric analysis was performed to explore the current research status and development trends for missing persons globally and in East Asia and to identify research hotspots and frontiers relating to this topic. A search was conducted to identify relevant literature on missing persons using the Web of Science Core Collection database for the period 2000–2021. Subsequently, a knowledge map was constructed using CiteSpace software to perform a visual analysis of the distribution of authors and institutions, journals, and national/regional distribution; citation frequency; high-frequency keywords; and emerging research hotspots. The results showed firstly that discussions on missing persons and related topics in East Asia are held at the regional scale. There is a paucity of research on this topic, which has been conducted on a limited scale, lacks depth and possibly innovation, and entails limited discussion in this region. Secondly, there is a lack of social science research on missing persons and related topics worldwide. Thirdly, relevant research in East Asia should continue to preserve its own characteristics, effectively addressing current issues and enabling more people to participate in social science-oriented discussions focusing on the topic of missing persons. This approach provides a promising direction for pursuing the sustainable development of the topic of missing persons. Key points The strengths and weaknesses of current research on missing persons in East Asia were identified by comparing the respective literatures on missing persons and related topics in East Asia and worldwide during the period 2000–2021. Bibliometric analysis was performed using CiteSpace visual charts to explore keywords, authorship and co-authorship, intercountry collaboration, and other relevant co-citationities. Insights were obtained on current research breakthroughs relating to the topic of missing persons, and cutting-edge social science research on this topic was identified. [ABSTRACT FROM AUTHOR]
