运用灰色预测理论，通过对有限时间范围内的文献引用频次的线性微分拟合，给出了文献老化的历时研究半衰期的测定公式。以《中国药理学报》、《药学学报》、《中国药学杂志》、《中草药》、《中国中药杂志》的引文为样本数据源，跟踪了1981年发表的文献的引用频次，并测定出药学期刊文献老化的历时半衰期大约为6．4年。 相似文献

通过对参考文献数量与质量的现状分析可知:近年来,参考文献著录数量有明显增加的趋势,但与国际刊物相比,我国刊物的引文数量仍然偏低;质量上则存在引用文献类型不当、引用文献陈旧、引用文献单调、引用文献内容不准确等问题。因此,必须合理增加参考文献数量,增强文献质量意识,从而提高学术论文的质量。 相似文献

[目的/意义]针对被引频次指标在学术论文评价中的局限性,提出基于多维度引用特征的学术论文评价方法,提高引文指标在单篇论文评价中的可靠性。[方法/过程]通过被引频次标准化消除学科、时间等因素的影响,作为频次指标;通过引用主体的重要性、引用时间跨度、引用强度、引用位置、引用情感、主题相似度6个维度的引用特征,区分不同引用中被引文献对施引文献的作用,作为特征权重;将频次指标和特征权重相结合,对学术论文进行定量评价。[结果/结论]改进基于引用的学术论文评价方法,有效解决被引频次指标对所有引用同等对待的问题。该方法的评价结果比被引频次指标更加合理,还能更细致地剖析论文的被引特征。 相似文献

科技期刊文献引用分布规律的探讨 总被引：2，自引：1，他引：1
董建军 《中国科技期刊研究》2013,24(4):688-693
通过随机选取学科、学科子类以及期刊来研究科技期刊文献引用分布规律,按照被引频次由高到低的顺序统计不同被引频次的文献量.研究发现无论是从学科层次来分析还是期刊层次来分析论文的引用在发表后的2～6年间均呈现偏态分布,随着被引频次的增高被引文献量逐渐降低,占期刊已被引文献数30％的论文提供50％以上的引用,随着论文发表时间的延长这种引用的集中趋势有所增强,但是变化幅度不大. 相似文献

In earlier papers the authors focused on differences in the ageing of journal literature in science and the social sciences. It was shown that for several fields and topics bibliometric standard indicators based on journal articles need to be modified in order to provide valid results. In fields where monographs, books or reports are important means of scientific information, standard models of scientific communication are not reflected by journal literature alone. To identify fields where the role of non-serial literature is considerable or critical in terms of bibliometric standard methods, the totality of the bibliographic citations indexed in the 1993 annual cumulation of the SCI and SSCI databases, have been processed. The analysis is based on three indicators, the percentage of references to serials, the mean references age, and the mean reference rate. Applications of these measures at different levels of aggregation (i.e., to journals in selected science and social science fields) lead to the following conclusions. 1. The percentage of references to serials proved to be a sensitive measure to characterise typical differences in the communication behaviour between the sciences and the social sciences. 2. However, there is an overlap zone which includes fields like mathematics, technology oriented science, and some social science areas. 3. In certain social sciences part of the information seems even to be originated in non-scientific sources: references to non-serials do not always represent monographs, pre-prints or reports. Consequently, the model of information transfer from scientific literature to scientific (journal) literature assumed by standard bibliometrics requires substantial revision before valid results can be expected through its application to social science areas. 相似文献

A co-citation cluster analysis of a three year (1975–1977) cumulation of the Social Sciences Citation Index is described, and clusters of information science documents contained in this data-base are identified using a journal subset concentration measure. The internal structure of the information science clusters is analyzed in terms of co-citations among clusters, and external linkages to fields outside information science are explored. It is shown that clusters identified by the journal concentration method also cohere in a natural way through cluster co-citation. Conclusions are drawn regarding the relationship of information science to the social sciences, and suggestions are made on how these data might be used in planning an agenda for research in the field. 相似文献

The greatest number of open access journals (OAJs) is found in the sciences and their influence is growing. However, there are only a few studies on the acceptance and thereby integration of these OAJs in the scholarly communication system. Even fewer studies provide insight into the differences across disciplines. This study is an analysis of the citing behaviour in journals within three science fields: biology, mathematics, and pharmacy and pharmacology. It is a statistical analysis of OAJs as well as non-OAJs including both the citing and cited side of the journal to journal citations. The multivariate linear regression reveals many similarities in citing behaviour across fields and media. But it also points to great differences in the integration of OAJs. The integration of OAJs in the scholarly communication system varies considerably across fields. The implications for bibliometric research are discussed. 相似文献

Systematic evaluations of publicly funded research sometimes use bibliometrics alone or bibliometric-informed peer review, but it is not known whether bibliometrics introduce biases when supporting or replacing peer review. This article assesses this by comparing three alternative mechanisms for scoring 73,612 UK Research Excellence Framework (REF) journal articles from all 34 field-based Units of Assessment (UoAs) 2014–17: REF peer review scores, field normalised citations, and journal average field normalised citation impact. The results suggest that in almost all academic fields, bibliometric scoring can disadvantage departments publishing high quality research, as judged by peer review, with the main exception of article citation rates in chemistry. Thus, introducing journal or article level citation information into peer review exercises may have a regression to the mean effect. Bibliometric scoring slightly advantaged women compared to men, but this varied between UoAs and was most evident in the physical sciences, engineering, and social sciences. In contrast, interdisciplinary research gained from bibliometric scoring in about half of the UoAs, but relatively substantially in two. In conclusion, out of the three potential sources of bibliometric bias examined, the most serious seems to be the tendency for bibliometric scores to work against high quality departments, assuming that the peer review scores are correct. This is almost a paradox: although high quality departments tend to get the highest bibliometric scores, bibliometrics conceal the full extent of departmental quality advantages, as judged by peer review. This should be considered when using bibliometrics or bibliometric informed peer review. 相似文献
