摘要: 通过科学计量学方法,以Web of Science数据库1985—2015年发表的学术论文为基础,利用知识图谱分析软件VOSviewer和Sci-2工具包对稀土研究领域进行可视化分析。首先通过文献共被引分析稀土研究的知识基础,其次通过关键词共现分析探测稀土研究领域的研究前沿,最后通过突现检测分析稀土研究领域的研究趋势。研究结果表明:中国的发文量在国家/地区中居于首位,中国科学院在相关机构中发文量最多;稀土研究知识基础的重要文献形成3个聚类;稀土研究前沿的主题主要形成稀土发光材料、稀土永磁材料、稀土储氢材料、稀土化合物和化学合成法5个聚类;稀土研究趋势主要的突现关键词包括稀土化合物、荧光粉等。

关键词: 稀土, 知识图谱, 知识基础, 研究前沿, 研究趋势

Abstract: This paper, based on Web of Science Database's 19852012 articles, uses VOS viewer and Sci2 to study by visualizing the REE research domains. REE knowledge basics are studied through references' quoted times, research advances through key words, and research trend through REE testing and assay. Chinese REE articles rank the top with Chinese Academy of Science contributing the most. References regarding REE knowledge basics are divided into three clusters, REE research advances into five clusters, luminescence materials, permanent magnetic materials, hydrogen storing materials, REE compounds and Chemical synthesis. REE research trend are marked by key words REE compounds and phosphors.

Key words: REE, knowledge atlas, knowledge basics, research advances, research trend
