[目的/意义]21世纪以来，在新一轮科技革命的影响下，知识组织研究主题、方法和应用呈现出新的特征， 通过总结凝练国外相关研究主题与特征，能为我国该领域全方位探索提供参考。[方法/过程]首先全面收集2000- 2022年国外知识组织相关文献，采用内容分析法对其逐一编码，以获取研究主题及研究内容的特征。[结果/结论] 研究发现国外知识组织研究主题多元，研究重心从数字化向数据化、语义化转变；重视知识组织系统的质量评估； 知识组织方式呈现技术、众包和专家并存趋势；领域应用注重面向特定情景的研究。未来我国的研究应该：（1）关 注中文数据基础设施建设，推动语义化、关联化进程；（2）建立合理的评估体系，引领知识组织创新；（3）“众包+技 术+专家”三轮驱动，加快智慧数据的组织；（4）拓展特定领域的应用实践，提升知识组织服务水平。

[Purpose/significance] Since the 21st century, the themes, methods and applications of Knowledge Organi⁃ zation (KO) research have presented new features under the influence of the new generation of scientific and technologi⁃ cal revolution. By summarizing and refining relevant research topics and features abroad, this paper can provide refer⁃ ence for Chinese scholars in this field. [Method/process] This study first comprehensively collected the relevant litera⁃ ture of foreign KO from 2000 to 2022, and then used content analysis to code them one by one to obtain the characteris⁃ tics of research topics and research contents of KO. [Result/conclusion] Important findings of this study include: the KO research topics tend to be diversified, and the focus has shifted from digitization to dataization and semantics; the quality assessment of knowledge organization systems is emphasized; the organization method presents a coexistence trend of technology, crowdsourcing and experts; application areas has centered on scenario-oriented research. It is sug⁃ gested that Chinese KO research should: (1)focus on the construction of Chinese data infrastructure and promote the process of knowledge integration and association;(2)establish a reasonable evaluation system to improve KO quality; (3) accelerate the organization of intelligent data by "crowdsourcing + technology + experts"; (4)expand the application in specific fields to improve the service level.
