为了提升参考文献的自动化加工水平和准确率,通过编写VBA(Visual Basic for Applications)程序,利用HTTPS协议自动获取参考文献的DOI信息,进一步利用获取的DOI信息从CrossRef、PubMed和ADS数据库挖掘出文献的元数据信息,并按照期刊的具体格式规范文后参考文献的加工和XML信息标引.经测试,运行VBA程序后,每50条参考文献只需5 min即可完成解析和文献加工,大大提升了编辑效率和准确率.认为对参考文献的体例和各数据库的API接口熟练掌握和使用是程序运行成功的关键. 相似文献

This study replicates and extends Yates and Chapman's [(2007), Behavioral & Social Sciences Librarian, 26(1), 39–51] study of references from Communication Monographs, Communication Research, and Journal of Communication for the years 2010 and 2015 to draw further conclusions on the use of monographs in journal literature in the field of communication. Results show that the use of monographs in these journals has been outpaced by references to journal articles by a ratio of 5 to 1. The references were further analyzed by date and publisher. The authors then selected a random sample of the monographs cited in the journals to explore the availability of these monographs in electronic format and found that many are available as ebooks, particularly the more recent titles. The authors also examined the references from a collection of scholarly books in communication from 2005, 2010, and 2015 and found that the use of monographs may be declining slightly. The most notable trend in these references was the increase in the number of references to items in other formats such as film, television, comic books, and websites. The authors conclude that the monographs crisis is indeed affecting citation patterns in the field of communication. 相似文献

Bus-based systems are very attractive because they are simple and easy to use. Most of the models available in the literature for bus-based systems are for circuit-switched systems. The throughput of a packet-switched system is higher than that of the circuit-switched system due to the fact that in a packet-switched system all the resources can be used at their own speed. Some models of packet-switched multiple bus systems are available in literature [2], where read and write references are treated equally. This means that a processor is blocked after it submits a memory reference, and it is kept in the blocked state until it receives the operand (for a read reference) or an acknowledge signal (for a write reference) from the memory. Some extra throughput can be obtained if the processors are allowed to go back to computation immediately after they submit write references. Stanford's DASH multiprocessor system [20] uses such a technique.This paper shows analytical models to determine the performance of packet-switched multiple and partial multiple bus systems, where the processors are blocked after read references but not after write references. The analytical models have been verified by the simulation models. The results show that when 20% of the memory references are for write operations, 12% more throughput can be achieved if the processors are not blocked after write references. 相似文献

量化测度研究成果的学科交叉性是交叉科学研究中的重要问题,对于理解学科交叉现象与学科发展规律具有重要意义。基于引文关系的学科多样性测度是学科交叉测度的主流方法,现有的研究大多将论文的参考文献作为一个整体来探究论文的学科交叉程度,忽略了不同章节参考文献的分布、不同参考文献的重要程度以及相同参考文献的多次引用等情况。本文尝试基于论文中不同章节的引文标注位置来探究不同章节的学科交叉程度,进而根据不同章节参考文献的重要程度来计算论文的加权学科交叉度。以2007-2016年发表在PLoS ONE期刊上的研究论文为例,研究结果表明:(1)引言(Introduction)、讨论(Discussion)、方法(Method)和结果(Results)四个章节的学科交叉程度依次降低;(2)与基于整体参考文献的学科交叉测度相比,基于引文标注位置的加权学科交叉度数值相对较低且分布更为集中。基于引文标注位置的学科交叉测度方法可以从内容的微观层面更加细致地测度论文的学科交叉水平,为交叉科学研究成果的测度和高交叉研究成果的识别提供了新的视角与思路。 相似文献

The purpose of this research is to illustrate the use of the gamma distribution to model the ages of references in published research, and to demonstrate that the two gamma distribution parameters characterise a field of research in a manner that is complementary to and more nuanced than the Price Index or mean age of references.Minimum Distance Estimation is shown to produce robust estimates of the gamma distribution parameters because of the insensitivity of the Kolmogorov–Smirnov test in the tails of the distribution.Using a sample of 816 articles from 26 different journals across six subject areas, it is shown that the gamma distribution is at least as good as a lognormal distribution to model the ages of references in research articles.The two gamma distribution parameters indicate the rate of publication of new knowledge within the respective discipline and the citing behaviour in terms of the recency of references. Interpretation of these gamma distribution parameters enables a more nuanced and granular interpretation of the distinctiveness of disciplines, sub-disciplines, formats of publication and the distribution of references within articles than possible using the Price Index, half-life or mean age of references. 相似文献

Cited references and suggested readings from undergraduate textbooks can help collection development librarians define parameters of newly emerging fields of study. This study examined the citations from four heavily used textbooks in police administration in order to gain an overview of the resources experts use to introduce their subject to undergraduates. Books were cited more than journals. Government publications, court cases, and association publications contributed substantially to the field. Monographic and serial resources in business, management, public affairs, labor relations, sociology, and law were cited frequently, reflecting the interdisciplinary nature of the field. Materials from the 70s and 80s were cited more often than current resources. Using the compiled data as a base, the author suggests implications for building collections geared toward students in the field. 相似文献

[目的/意义] 针对60年间作者引用行为演变的分析,了解引文评价的局限性,促进学术论文评价方法的发展和完善。[方法/过程] 通过对1957-2017年物理学和哲学代表性期刊的280篇论文的3 314条参考文献和5 222次引文进行识别,判断和统计其在不同年代的引用特征,并讨论引用行为的演变趋势对引文评价的可能影响。[结果/结论] 通过调查发现如下结论：一是期刊论文在参考文献载体类型和年代分布上没有明显变化,但在篇均参考文献量、参考文献文内平均被引用次数、论文的引用认同和引用深度等方面存在明显变化趋势;二是引用行为的变化,使得引文分析作为学术论文评价的依据受到质疑。论文篇均参考文献量的增长以及深度引用与负面引用比重的下降,使得引文评价的参考性减弱。 相似文献

The development of services provided by the National Library of Medicine (NLM), which dates back to 1836, is described. MEDLINE, a database of 10-plus million references and abstracts to the world's biomedical literature, was put on the World Wide Web for free searching in 1997 as a system called PubMed, whose use has grown to over 250 million searches per year. PubMed features a variety of links between MEDLINE references and related information – full-text journal articles, DNA sequence data, medical knowledge bases, etc. – at websites within and outside NLM. PubMed is a major component of a larger NLM system, Entrez, which integrates access to a number of genome-related databases with linking features similar to those of PubMed. The newest linked service, which became a reality in February 2000, is PubMed Central, the National Institutes of Health's free repository for primary research reports in all the life sciences. 相似文献
