| 摘 要： | 目的/意义]学术谱系以知识传承的方式助推科学发展。研究知识传承特征，探索学术谱系传承模式及其学术产出影响效能，为探索人才成长规律及人才政策制定提供参考。方法/过程]基于LDA主题模型，以遗传学领域谈家桢为核心的学术谱系成员发表的期刊文献为研究对象，对该谱系成员的研究主题进行抽取，借鉴生物学"遗传"与"变异"的概念，根据主题相似度将谱系成员划分为"遗传学者""变异学者"和"非遗传非变异学者"，并对三种学者的学术绩效进行分析。结果/结论]分析结果表明，谈家桢学术谱系内"遗传学者"和"变异学者"的学术绩效相对较高；"非遗传非变异学者"的数量占比最多，但学术绩效相对较低；"遗传学者"与"变异学者"在不同主题下的分布具有明显差异。

| Abstract: | Purpose/significance] Academic pedigree promotes science development by the way of knowledge inheritance. It is of great reference value to study the characteristics of knowledge transmission and explore the effect of inheritance model on academic output, and it is of great reference value for the relevant departments to find out the law of talent growth and formulate scientific and technological personnel training policy.Method/process] By the method of LDA topic model, this paper took the journal literature of genetics published in CNKI database as research object, and quoted the concept of "hereditary" and "variation" in biology. Then, according to the topic similarity, we divided pedigree members into "hereditary scholars", "variation scholars" and "non-hereditary non-variation scholars", and analyzed the academic performance of these three kinds of scholars.Result/conclusion] The results show that the academic performance of "hereditary scholars" and "variation scholars" in the academic pedigree of Tan Jiazhen is relatively high; The number of "non-hereditary non-variation scholars" is the largest, but their academic performance is relatively low; For different topics, the distribution of "variation scholars" and "hereditary scholars" is significantly different. |
