国内船舶碰撞事故科研产出及主题趋势挖掘

为了全面认识国内船舶碰撞研究的整体现状及趋势，基于中国知网的2000—2016年506篇船舶碰撞学位论文和1957—2016年1 620篇期刊论文，使用科学计量和知识图谱的方法进行了可视化分析。结果表明:学位论文和期刊论文的产出主要集中以大连海事大学、上海海事大学、上海交通大学以及武汉理工大学为核心形成不同的研究团队。关于船舶碰撞的学位论文主要集中在AI、船舶避碰、数值仿真等方面，期刊论文的热点主要分布在船舶避碰、碰撞事故、碰撞危险等方面。整体来看，2000年以后学位和期刊论文在研究上的趋势是相近的，都在关注AI、数值模拟方法和碰撞责任主体等方面的避碰主题，近期新兴的研究更加关注在一些船舶碰撞微观的层面。

Scientific research output and topics trends mining of ship collision accidents in China

In order to know the overall current status and trends of research on ship collision in China, the visualized analysis was carried out by using the methods of scientometrics and knowledge map based on 506 theses from 2000 to 2016 and 1620 journals papers from 1957 to 2016 about the ship collision from the CNKI database. The results showed that the output of the theses and journals papers concentrated on different research groups formed by Dalian Maritime University, Shanghai Maritime University, Shanghai Jiao Tong University and Wuhan University of Technology as the core. The theses about the ship collision mainly focused on the AI, ship collision avoidance, numerical simulation, etc., and the hot topics of the journals papers mainly distributed on the ship collision avoidance, collision accident, collision risk, etc. On the whole, the research trends of the theses and journal papers after 2000 were similar, focusing on the topic of collision avoidance in the aspects of AI, numerical simulation method, responsibility subject of collision, and so on. The emerging research in the recent years more concerned about some micro level of ship collision.
