Abstract

Utilizing a visual analysis of the literature on postmortem interval (PMI) estimation indexed by Web of Science (WOS), this study investigates developmental trends and research hot points across each 5-year period from 2006 to 2020. Additionally, collaborative efforts among authors, countries, and institutions were examined. Research hot points, high-frequency keywords, authors, countries and institutions in relevant papers were analyzed using CiteSpace.5.7.R2 information visualization analysis software over the past 15 years. The literature related to PMI estimation has witnessed consistent growth over time. In the keyword co-occurrence network, several impactful terms stand out, including blowfly, mitochondrial DNA, and emerging concepts like virtual autopsy. Technological advancements, such as RNA stability analysis and virtual autopsy tools, have played a pivotal role in shaping the direction of PMI research. Scientific research institutions dominate the high-frequency affiliations within the institutional cooperative network. Additionally, the country cooperative network exhibits a trend of co-occurrence and multi-clustering. As science and technology continue to advance, traditional PMI estimation methods mature while novel interdisciplinary approaches drive innovation. By identifying emerging trends and research hotspots, this study provides a roadmap for future investigations, guiding researchers toward new opportunities in PMI estimation.

死后间隔估计趋势和协作网络的可视化分析:一项为期 15 年的研究(2006-2020 年)。
本研究利用科学网(Web of Science,WOS)索引的死后间隔(PMI)估计文献的可视化分析,调查了从 2006 年到 2020 年每个 5 年期间的发展趋势和研究热点。此外,还考察了作者、国家和机构之间的合作情况。使用CiteSpace.5.7.R2信息可视化分析软件对过去15年相关论文中的研究热点、高频关键词、作者、国家和机构进行了分析。与 PMI 估算相关的文献随着时间的推移持续增长。在关键词共现网络中,几个有影响力的术语脱颖而出,包括蝇类、线粒体DNA以及虚拟尸检等新兴概念。RNA 稳定性分析和虚拟解剖工具等技术进步在塑造 PMI 研究方向方面发挥了关键作用。科研机构在机构合作网络的高频附属关系中占据主导地位。此外,国家合作网络呈现出共同出现和多聚类的趋势。随着科学技术的不断进步,传统的 PMI 估算方法日趋成熟,而新型的跨学科方法则推动了创新。本研究通过识别新兴趋势和研究热点,为未来研究提供了路线图,引导研究人员把握 PMI 估算的新机遇。
