论文部分内容阅读
采用CNKI的学术不端文献检测(AMLC)系统,对《中山大学学报(医学科学版)》230篇来稿进行了重复文字比例的检测,发现约有50%的文章存在不同程度的重复文字现象,不同重复比例的文章数呈偏态分布,罕见重复文字比极高的文章。对其中重复比例较高的64篇文章进行了其各部分重复文字标记数的比较,发现医学论文中方法、结果和讨论部分重复文字标记数较多,而摘要、引言和材料等部分较少。对其中的临床研究和基础研究文章进行了比较,发现基础研究论文在引言、方法和结果部分重复文字的标记数高于临床研究论文,但总复制比却没有发现有统计学意义的差别。认为反对和抵制学术不端行为,是多个系统和部门共同协作的系统工程,期刊编辑也应尽其学术把关的职责。
Using CNKI’s AMLC system, we detected the repetitive text ratio of 230 articles published in “Journal of Sun Yat-sen University (Medical Science Edition)” and found that about 50% of the articles had different degrees of repetitive writing, The number of articles with different repetition ratio was skewed distribution, rare repetitive text than the very high article. Sixty-four articles with higher repetition ratio were compared in terms of repetitive number of words in each part. It was found that there were many repetitive words in the method, the result and the discussion in the medical essay, while the summary, the introduction and the material were few. The clinical research and basic research articles were compared and found that the basic research papers in the introduction, methods and results of part of the repetitive text labeling number is higher than the clinical research papers, but the total copy ratio did not find significant differences. To think that opposing and boycotting academic misconduct is a systematic project in which many systems and departments cooperate with each other, and periodical editors should also exercise their academic duties.
