从学位论文化的引文分析看硕士研究生的文献需求   总被引:3,自引:0,他引:3  
何怡  徐芮 《津图学刊》2002,(3):40-44
通过对天津医科大学2001年86篇硕士研究生学位论文所引文献的数量、语种、文献类型,年代及出版物等的统计调查,并与国内同学科硕士学位论文的引文分析情况进行比较,发现硕士生在参考文献时首选英文文献,期刊类文献为主要文献源,外文期刊引用明显高于中文期刊,中文多选自发表后第3年的文献,外文则多选自发表后第4至6年期间的文献。本文归纳出我校研究生常用的72种中文、87种外文期刊,对图书馆适当调整期刊的订购,进一步提高馆藏期刊收藏的质量等方面,提供了一定的参考依据。  相似文献

王春霞 《晋图学刊》2004,(3):4-6,75
本文以计算机技术学科类具有代表性的10种期刊2001年发表的全部论文为统计对象,收集其引用文献进行该学科的文献老化研究。对该学科引文的时序分布、当年指标、最大引文年限、引文半衰期、普赖斯指数等文献老化量度指标进行统计分析。结果表明:该学科的中、外文文献最大引文年限分别为第3和第4年,引文半衰期为5.5年,普赖斯指数为45.8%,并提出分别以该学科中、外文文献发表后的11年和16年作为文献保存年限参考值,建议把该学科近5年内发表和出版的文献作为文献订购的时限。  相似文献

中西部科技文献信息资源保障体系建设的思考   总被引:8,自引:0,他引:8  
目前,中西部地区科技文献信息资源保障体系普遍存在着“三多三少”:一是老化的多,新颖的少,科技文献资源大多是20世纪80年代以前出版的,失去创新价值;二是残缺的多,完整的少,如某省20世纪80年代年收藏外文期刊3000多种,近年收藏外文期刊仅300多种〔1〕;三是中文文献较多,外文文献奇缺。据2002年我国主要高校图书馆进口报刊预订数统计,中西部地区订购原版外文期刊4666种,仅占全国高校外文期刊订购数(27774种)的16.80%〔2〕。又据全国文献资源调查结果显示,西北地区中文文献的满足率比华北、华东地区低6~7个百分点;西南地区外文文献满足率比…  相似文献

对上海师范大学数学系教师发表的论文以及引文数据进行整理分析,表明数学教师越来越重视外文期刊,对中文期刊质量不认同,他们对专著仍保持着较高的关注度。同时对图书馆就引文文献保障情况进行分析,得出数学学科文献保障主要依赖于订购的电子期刊,这些电子期刊分散于多个数据库中,纸质期刊的辅助作用微乎其微,专著保障率较低等结论,以期对数学学科文献资源建设起到借鉴作用。  相似文献

利用文献计量与内容分析方法,分析二十年(2001—2020年)来中外主要期刊中发表的关于档案利用研究的论文,说明中外档案利用研究热点的共性和差异。通过研究发现,中文期刊文献的关键词专指度更高、专业性更强,外文期刊文献的关键词范围更广泛,并不仅限于档案利用的研究领域,文献的内容更综合。因而,中外学者的有关研究,有基本共性,但差异性似乎更大。  相似文献

外文期刊的编译服务,主要是将外文期刊中的论文编译(翻译、节译)成中文,也可以在阅读的基础上,用中文编写论文综述和介绍,以此提高外文期刊利用率。一、外文期刊的编译服务消除了读者利用外刊的语言障碍众所周知,在知识与情报交流过程中出现的人类的自然语言不通的问题,已成为知识与情报交流的重大障碍。据联合国教科文组织的资料表明。目前世界上的科学文献有2/3是用英文出版的,而全世界有2/3专业人员不能阅读英语文献,不少掌握英语的专业人员又不能阅读其他语言的文献。尽管我馆对外文期刊进行了大量二次文献整理加工开发,如每年及时编制《预订外文及港台报刊目录》(中外文对照),专门编制外文会计论文篇名索引卡、世界银  相似文献

Aim:The purpose of this study is to identify and describe the citing behavior of geomatics postgraduate students at the Wuhan University in China. These students constitute one of the main user groups of Wuhan University Library and the analysis of their use of literature (through the means of citation analysis) can yield valuable insights against which to benchmark and inform collection development policy and other services at the Information Technology Library (ITL) at Wuhan University.Design/methodology/approach:In this project, 9317 citations in 21 PhD and 180 MSc theses submitted at the Wuhan University in the years of 1988, 1996, and 2004 were analyzed. All cited materials were divided by output format (monographs, proceedings, journal articles) and the more in-depth analysis was conducted for all cited journals. The following characteristics of the cited journal literature were analyzed: subject, age, language, and dispersion of journal titles.Findings:An increased use of journal literature in bibliographies of geomatics theses was observed over time. A trend to increase citations to international conference proceedings was also noted as well as a trend to cite more journals in disciplines other than surveying and mapping. It was also noted that, over time, citations to documents in languages other than Chinese and English have significantly decreased (in some cases, disappeared). Large dispersion among the most frequently cited journals in different time periods (only 25% of titles were repeated in 1988, 1996, and 2004 top ranking journal lists) was also noted. It was also noted that the core of geomatics literature is expanding (it now takes 42% of journal titles to cover 80% of all citations).Practical implications:By analyzing citation patterns of the graduate students of geomatics in China, we can track the developments and changes within that discipline in China and can compare these trends internationally (e.g. increased role of a journal, the importance of conference proceedings, domination of the English-language sources, dispersion of journal literature, and increasing multidisciplinarity of the discipline). The techniques and methods used in this study can be replicated to study other disciplines. Also, it is hoped that the findings of this research will inform collection development planning, development of reference services, and information literacy training.  相似文献

Journal weighted impact factor: A proposal   总被引:3,自引:0,他引:3  
The impact factor of a journal reflects the frequency with which the journal's articles are cited. It is the best available measure of journal quality. For calculation of impact factor, we just count the number of citations, no matter how prestigious the citing journal is. We think that impact factor as a measure of journal quality, may be improved if in its calculation, we not only take into account the number of citations, but also incorporate a factor reflecting the prestige of the citing journals relative to the cited journal. In calculation of this proposed “weighted impact factor,” each citation has a coefficient (weight) the value of which is 1 if the citing journal is as prestigious as the cited journal; is >1 if the citing journal is more prestigious than the cited journal; and is <1 if the citing journal has a lower standing than the cited journal. In this way, journals receiving many citations from prestigious journals are considered prestigious themselves and those cited by low-status journals seek little credit. By considering both the number of citations and the prestige of the citing journals, we expect the weighted impact factor be a better scientometrics measure of journal quality.  相似文献

Using 17 open-access journals published without interruption between 2000 and 2004 in the field of library and information science, this study compares the pattern of cited/citing hyperlinked references of Web-based scholarly electronic articles under various citation ranges in terms of language, file format, source and top-level domain. While the patterns of cited references were manually examined by counting the live hyperlinked-cited references, the patterns of citing references were examined by using the cited by tag in Google Scholar. The analysis indicates that although language, top-level domain, and file format of citations did not differ significantly for articles under different citation ranges, sources of citation differed significantly for articles in different citation ranges. Articles with fewer citations mostly cite less-scholarly sources such as Web pages, whereas articles with a higher number of citations mostly cite scholarly sources such as journal articles, etc. The findings suggest that 8 out of 17 OA journals in LIS have significant research impact in the scholarly communication process.  相似文献

[目的/意义]在学术交流日趋国际化的背景下,本文拟探索引文国际化与被引量之间的关系,力图回答良好的国际视野是否有助于提升论文的学术影响力这一学界普遍关注的问题。[研究设计/方法]以社会科学为研究对象,选取管理学、图书情报学和新闻传播学的181,406篇CSSCI论文为研究样本,采用相关分析、非参数检验与回归分析的方法研究引用外文期刊论文的数量、学术质量、学科领域、时效性对论文被引量的影响。[结论/发现]在控制了文献类型、期刊声誉等若干可能影响论文被引量的因素后,发现样本论文的引文国际化水平对其被引量具有显著的正向影响。具体而言,引用外文期刊论文的数量越多、平均学术质量越高、学科专属度越高、平均时效性越强的论文具有更高的被引量。[创新/价值]证实了国际视野有助于提升中文社科论文的学术影响力,并提出了有针对性的建议。  相似文献

This study, conducted at the Indiana University School of Dentistry Library using citation analysis, examined graduate dental student theses citations to determine the nature of materials cited, journal ownership, journal citation frequency, and citation age distribution. The results were compared to other scientific discipline citation analyses. Study results indicated that for the period studied, masters dental students, like medical and science students, cited recently published scholarly dental journal literature. The majority of the journals cited were owned by Indiana University system libraries. Areas for further research include faculty resource usage, e-journal impact, and interdisciplinary resource use.  相似文献

林业类科技核心期刊文献引用研究   总被引:1,自引:0,他引:1  
为全面、深入分析文献引用对林业类科技核心期刊质量的影响,通过资料分析,采用数理统计方法,选择同一层次的5家林业类科技核心期刊,对其2014年全年的参考文献的引用情况(篇均引文量、引文类型、引文语种、引文的时效性、期刊自引率)进行统计和分析.结果表明:5家期刊参考文献的引用情况不尽相同,篇均引文量需要提高;参考文献来源类型主要是期刊;语种以中文为主,其次是英文,其他语种引用比较少;参考文献时效性和期刊自引率控制较为合理,但有提升空间.通过统计数据分析,希望期刊编辑重视刊发文章引文的各项指标,从而提高刊发文章质量.  相似文献
