The objectives of the study were to demonstrate the suitability of methodology based on a text mining toolset for detecting trends in scientific papers and to find trends that were present in the field of project management during the research time span (2000–2019).,An approach based on text mining tools supported by expert analysis was adopted due to an extensive number of publications in the field of project management. The novelty of the approach lies in the proposed method of trends discovery instead of the commonly used trends predefinition. The use of computer support allowed the full texts of papers, and not only abstracts, to be analysed, which significantly increased the reliability of the achieved results. Overall, 3,544 papers from seven journals were analysed.,As a result, 43 trends were discovered including seven long-lasting, four declining, 17 emerging and 15 ephemeris trends. Trends were analysed in comparison with the results of previous studies and project management frameworks. New trends and potential gaps were discussed.,The results highlight the topics of research that gain popularity among researchers, and which are related to the current problems that arise in project management. Therefore, the results can help focus studies on the most important areas, as well as find new ones which are not so popular yet. The knowledge of current trends is also important for those project managers who seek to improve the efficiency of their work.

二十一世纪项目管理研究的演变

这项研究的目的是证明基于文本挖掘工具集的方法对于检测科学论文趋势的适用性，并发现研究时间跨度（2000-2019年）在项目管理领域中存在的趋势。由于在项目管理领域有大量出版物，因此采用了基于文本挖掘工具并得到专家分析支持的方法。该方法的新颖之处在于所提出的趋势发现方法，而不是常用的趋势预定义。使用计算机支持可以分析论文的全文，而不仅仅是摘要，这大大提高了所获得结果的可靠性。总共分析了来自7种期刊的3,544篇论文。结果，发现了43种趋势，包括7种持久，有4个下降，17个新兴和15个星历趋势。与以前的研究结果和项目管理框架相比较，对趋势进行了分析。讨论了新的趋势和潜在的差距。研究结果突出了研究主题在研究人员中的流行，并与项目管理中当前出现的问题有关。因此，研究结果可以帮助将研究重点放在最重要的领域上，并找到尚未流行的新领域。对于那些寻求提高工作效率的项目经理来说，了解当前趋势也很重要。结果突出了研究主题在研究人员中越来越受欢迎，并且与项目管理中当前出现的问题有关。因此，结果可以帮助将研究重点放在最重要的领域上，并找到尚未流行的新领域。对于那些寻求提高工作效率的项目经理来说，了解当前趋势也很重要。结果突出了研究主题在研究人员中越来越受欢迎，并且与项目管理中当前出现的问题有关。因此，结果可以帮助将研究重点放在最重要的领域上，并找到尚未流行的新领域。对于那些寻求提高工作效率的项目经理来说，了解当前趋势也很重要。
