| 摘 要： | 目的/意义]从主题视角对环境科学领域的零被引论文进行分析,对比零被引论文与高被引论文在文章内容、外在指标方面的不同,揭示零被引论文存在的原因。方法/过程]首先,对来自Web of Science数据库的国内环境科学领域的260篇高被引论文、907篇零被引论文的摘要进行PLDA主题识别,然后通过主题相似度计算发现主题间的关联,以主题热度作为内部指标,发文时间、发文期刊作为外部评价指标,最后,把论文主题内容与外部指标结合进行零被引与高被引论文之间的相同主题、不同主题对比分析。结果/结论]在研究主题相同情况下,期刊的影响因子大小是影响零被引论文的主要因素;在主题不同的情况下,论文研究的主题内容是导致零被引论文的主要原因。

| Abstract: | Purpose/significance] This paper analyzes zero-cited papers in the field of environmental science from the perspective of the subject, to find the differences in the content of articles and external indicators between zero-quoted papers and high-cited papers and reveal the reason for the existence of zero-cited papers.Method/process] Firstly, the PLDA model was used to identify topics that from 260 high-cited papers and 907 zero-cited papers in the domestic environmental sciences database from the Web of Science database. Then the relevance of the topics was found through topic similarity calculation. With the topic popularity used as an internal indicator, the time of publication and the journals used as external evaluation indicators, a comparison analysis of zero-cited papers and high-cited papers was made by combining topical of the papers with external indicators.Result/conclusion] The experimental results show that under the same research topic, the influence of the journal is the main reason that influences the citation of the paper; under different topics, the topic is the main reason leading to zero-cited papers. |
