高被引文献是同学科领域中被高度认可的文献,也在一定程度上体现了论文的质量。而对高被引文献施引规律的探究可以在一定程度上探析高质量论文的理论基础和知识构成。以中文社会科学引文索引( CSSCI)中的图书情报学来源期刊作为检索对象,在CSSCI数据库中遴选出图书情报学的高被引论文,获取这些论文的参考文献信息。然后,用文献计量学的相关方法研究高被引论文的参考文献的被引特征,得出了高被引论文倾向于引用高被引文献的结论。结论一定程度支持了牛顿假说,即“我看得之所以比别人远是因为我站在巨人的肩膀上”,亦即“学术精英”(高被引论文)在学术科研领域起到了中流砥柱的作用。 相似文献

Although the citation relationships among papers can help in tracking and understanding the development of knowledge, few studies have noted that the content and sentiments of citations of a paper differ. Here, we use sentiment-labeled citation data to construct a directed signed citation network, in which an author may agree with or criticize the cited paper and these represent different ways of inheriting knowledge. The dataset we use consists of 9,038 papers in the field of Computational Linguistics, including 25,275 citations, with 20.8% positive citations, 8.6% negative citations and 70.6% neutral citations. We systematically quantify the structural patterns of negative citations, impact assortativity of involved papers, occurrence time distribution and consequences of receiving negative attention. Remarkably, we find that papers with different impacts have a similar probability of receiving negative citations, and highly cited papers tend to give negative citations to low-impact papers around but avoid giving negative citations to high-impact papers. Our research also reveals the random occurrence rules and colocation patterns of negative citation distribution. In addition, we show that, in the short term, around 60% of multiple negative citations is positively related to the impact of the cited paper while more than 80% are negatively related to the impact in the long run. Our findings explain the pattern by which negative citations occur and deepen the understanding of negative citations. 相似文献

This paper looks at how citations are perceived among scientists. Based on a questionnaire survey it traces the repertoire of views and experiences about citations that could be found among Norwegian scientists that had published highly cited papers. Their views circle around three issues: the relation between the quality (or importance or significance) of a paper and its citation history; the importance of visibility and how different sorts of factors play a role in determining citation in general and high citation in particular; and the fairness (or lack of fairness) of the system. Taken together, the respondents’ answers and comments offer an informal (and fragmented) sociology of citations and their role in the world of science. In the final section we discuss the relevance of our findings in respect to the increasing use of citation indicators in science policy and research evaluations. 相似文献

真实性、准确性、直接性与完整性是引用参考文献的首要准则,然而种种研究表明,当前的研究论著中引而不注、过度引用、模糊标注甚至虚假引用等不当引用行为日渐增多,这极大地影响了科学研究领域的学术风气,给读者阅读、期刊审稿及成果评定等工作带来了许多不便。本文利用文本相似度算法建立期刊引文有效性识别方法,试图从海量期刊引文数据中识别出期刊引文的真实有效性。实验表明,本文的期刊引文有效性识别方法在引文有效性方面实现了较好的识别效果,可为虚假引文的识别工作提供可靠的依据,从而为编辑人员发现、修正虚假引用问题提供帮助,彰显科学研究的严谨务实精神。 相似文献

Although citations are widely used to measure the influence of scientific works, research shows that many citations serve rhetorical functions and reflect little-to-no influence on the citing authors. If highly cited papers disproportionately attract rhetorical citations then their citation counts may reflect rhetorical usefulness more than influence. Alternatively, researchers may perceive highly cited papers to be of higher quality and invest more effort into reading them, leading to disproportionately substantive citations. We test these arguments using data on 17,154 randomly sampled citations collected via surveys from 9,380 corresponding authors in 15 fields. We find that most citations (54%) had little-to-no influence on the citing authors. However, citations to the most highly cited papers were 2–3 times more likely to denote substantial influence. Experimental and correlational data show a key mechanism: displaying low citation counts lowers perceptions of a paper's quality, and papers with poor perceived quality are read more superficially. The results suggest that higher citation counts lead to more meaningful engagement from readers and, consequently, the most highly cited papers influence the research frontier much more than their raw citation counts imply. 相似文献

The rate of citation duplication was examined in three databases: MEDLINE, BIOSIS, and LIFE SCIENCES COLLECTION. Duplicate citations were found to be more pertinent than unique citations. The duplicate citations came from a highly compact literature, while those from a single database were very widely scattered. The pertinent duplicated citations were more likely to be retrieved in searches that had more terms overall, had a higher percentage of thesaurus terms, and had terms which appeared in both title and abstract. These results suggest that the rate of duplication of citations in multidatabase searches may be used to rank output according to probable pertinence. 相似文献

Science’s main norms prescribe scientists to use citations as acknowledgements of cognitive content irrespective of geographical location. Previous studies, however, suggested that there is a considerable geographical bias in scientific citations. We argue that this geographical bias does not, in itself, falsify the notion that citations reflect acknowledgement of cognitive content, because cognitively related knowledge may be geographically concentrated as well. We analyse the role of organizational, regional and national co-location on citation likelihood for 5.5 million article pairs, and find that the geographical bias in citations is weak once cognitive relatedness is accounted for. Furthermore, we find that the effect of co-location on citation likelihood is strongest at the organizational level, weaker at the regional level, and weakest at the national level. In addition, we show that geographical co-location particularly increases the citation likelihood between two papers when knowledge relatedness between articles is low, suggesting that interdisciplinary research benefits most from co-location. Finally, we find that, when knowledge relatedness is high, the effect of geographical co-location on citation likelihood is non-existent. We discuss the implications regarding policies aimed to discourage strategic citations and to foster interdisciplinary research. 相似文献

[目的/意义]论文发表时间和所属学科的不同会对论文在后续的引文产生稀释效应的影响,发生在不同时间的引文也代表了不同的学术价值。从时序动态的视角设计一种学术影响力的评价指标,消除稀释效应的影响并能够体现不同时期的引文价值。[方法/过程]引入参考文献集合的篇均被引次数作为论文集合的基准值,消除由于发表时间和所属学科不同造成的稀释效应,进而再对不同统计时间点的被引次数赋予不同的权重,用以表征发生在不同时期的引文的不同价值。[结果/结论]以四川大学为例,选取ESI学科和研究人员作为评价对象进行实证研究,结果表明这一指标可以对学术影响力发展趋势不同的研究实体进行有效的区分。 相似文献
