Graduate students at the University of Manitoba were surveyed to find out if they used reference management software (RMS), features used, challenges and barriers to using RMS. Interest in different types of PDF management features and training options were also investigated. Both users and non-users of reference management software were invited to participate. Non-users managed their citations and references with a variety of other tools. The principal reasons for non-use were that students were not aware of options that were available, and the amount of time needed to learn the program. RMS users also mentioned the steep learning curve, problems with extracting metadata from PDFs, technical issues, and problems with inaccurate citation styles. Most of the students saved PDF documents to their computer. Students were most interested in full-text searching of PDFs, automatic renaming of PDFs, and automatically extracting citation metadata from a PDF. PDF annotation and reading tools were also of some interest. Mobile features were of the least interest. There were no statistically significant differences in the interest of PDF management features between the user and non-user groups but there were statistically significant differences in the interest of some of the training options between the groups. 相似文献

This study assesses whether eleven factors associate with higher impact research: individual, institutional and international collaboration; journal and reference impacts; abstract readability; reference and keyword totals; paper, abstract and title lengths. Authors may have some control over these factors and hence this information may help them to conduct and publish higher impact research. These factors have been previously researched but with partially conflicting findings. A simultaneous assessment of these eleven factors for Biology and Biochemistry, Chemistry and Social Sciences used a single negative binomial-logit hurdle model estimating the percentage change in the mean citation counts per unit of increase or decrease in the predictor variables. The journal Impact Factor was found to significantly associate with increased citations in all three areas. The impact and the number of cited references and their average citation impact also significantly associate with higher article citation impact. Individual and international teamwork give a citation advantage in Biology and Biochemistry and Chemistry but inter-institutional teamwork is not important in any of the three subject areas. Abstract readability is also not significant or of no practical significance. Among the article size features, abstract length significantly associates with increased citations but the number of keywords, title length and paper length are insignificant or of no practical significance. In summary, at least some aspects of collaboration, journal and document properties significantly associate with higher citations. The results provide new and particularly strong statistical evidence that the authors should consider publishing in high impact journals, ensure that they do not omit relevant references, engage in the widest possible team working, when appropriate, and write extensive abstracts. A new finding is that whilst is seems to be useful to collaborate and to collaborate internationally, there seems to be no particular need to collaborate with other institutions within the same country. 相似文献

Abstract Two open source extensions to the Firefox browser, LibX and Zotero, can improve the research process for library staff and users. Once configured and installed, LibX provides Firefox users with an additional browser toolbar and right-click functionality that can search a library's catalog, OpenURL resolver or federated search engine, as well as other Web sites. LibX also includes an autolinking feature, which embeds searchable links within other Web sites such as Google, Amazon, or Yahoo. Zotero merges the best features of other citation management programs with those of popular Web 2.0 services. Zotero users can store full citation information and sort, tag, annotate, and search these citations from within the Firefox browser. Zotero can also “scrape” citations from certain Web sites, allowing users to selectively save citations into their research collection. Zotero can generate complete bibliographies in MLA, APA, and Chicago styles. The abilities to remotely store, synchronize, and share Zotero collections are under development with a planned release date in fall 2007. 相似文献

ABSTRACT This study used citation analysis in conjunction with a subjective rubric with five validated criteria to assess the quality of a purposive sample of 452 education dissertation reference lists produced at a nontraditional institution from six doctoral programs. These programs used a variety of distance education models. The citations were then compared with the 100 reference lists selected from doctoral education programs at 10 traditional institutions. Criteria included the breadth of resources, depth of the literature review as shown through the citing of critical historical and theoretical works, depth as demonstrated through the scholarliness of citations chosen, currency, and relevancy. The study discusses how the expanded sample of traditional reference lists continued to demonstrate consistent patterns. In contrast, although the sample of reference lists from distance education programs was much expanded, the patterns of the subsets of reference lists at the nontraditional institution were significantly diverse. The patterns of 35 doctoral reference lists from another for-profit, nontraditional institution known for providing distance education were also examined to compare the results of the two nontraditional programs. Possible reasons for differences in citation patterns by traditional and nontraditional programs are discussed, and the possible role of distance education and program criteria are examined for insights they offer into the use of citation analysis as an assessment tool of the library research skills of doctoral students. 相似文献

With the growing population of undergraduate students on our campus and an increased focus on their success, librarians at a large midwestern university were interested in the citation management styles of this university cohort. Our university library spends considerable resources each year to maintain and promote access to the robust bibliographic management tool RefWorks. A team of librarians wondered whether RefWorks might be used by undergraduate students with the same perceived enthusiasm that we have sensed in graduate students and faculty. More generally, we explored how undergraduate students were managing their citations, if and what kinds of tools they were using to ease the process of creating bibliographies, and their general workflow in incorporating citations into their academic work. 相似文献

Most college and university libraries in British Columbia are using either EBSCO or Summon Discovery search services as a “one stop shop” for users to find, save, and cite resources for their projects. The citation generators that both EBSCO and Summon offer simplify the process of inserting citations into essays, however the citations need to be accurate for users to be able to submit citations that are error free. Considering this, this article looks at the accuracy of the citation generators each service offers. A total of twenty resources were picked from student library assignments for print books, eBooks, and articles in APA, Chicago, and MLA styles to determine the number and types of errors that occur for EBSCO and Summon Discovery. The error rate was substantial enough that caution must be used when creating citations using these tools and librarians should advise users that Discovery citation generators cannot be relied upon to provide accurate citations. 相似文献

The history and development of the Science Citation Index (SCI) is an example of the power of users in defining and influencing the development of a new technology. The SCI was developed as a tool for the historian of science for the purpose of tracing the history of ideas, but it was appropriated by users for purposes for which it was unintended – as a tool for evaluating the literature, individuals, institutions, and countries. The development of a citation tool gave rise to a debate over what is actually measured by citations. The citation‐as‐reward camp views citations as indicators of quality and impact, whereas the citation‐as‐persuasion camp views citations as no more than rhetorical devices. While neither view can fully explain how authors use citations, citation‐as‐reward prevails as the dominant interpretation. 相似文献

We address issues concerning what one may learn from how citation instances are distributed in scientific articles. We visualize and analyze patterns of citation distributions in the full text of 350 articles published in the Journal of Informetrics. In particular, we visualize and analyze the distributions of citations in articles that are organized in a commonly seen four-section structure, namely, introduction, method, results, and conclusions (IMRC). We examine the locations of citations to the groundbreaking h-index paper by Hirsch in 2005 and how patterns associated with citation locations evolve over time. The results show that citations are highly concentrated in the first section of an article. The density of citations in the first section is about three times higher than that in subsequent sections. The distributions of citations to highly cited papers are even more uneven. 相似文献

Past studies of citation coverage of Web of Science, Scopus, and Google Scholar do not demonstrate a consistent pattern that can be applied to the interdisciplinary mix of resources used in social work research. To determine the utility of these tools to social work researchers, an analysis of citing references to well-known social work journals was conducted. Web of Science had the fewest citing references and almost no variety in source format. Scopus provided higher citation counts, but the pattern of coverage was similar to Web of Science. Google Scholar provided substantially more citing references, but only a relatively small percentage of them were unique scholarly journal articles.The patterns of database coverage were replicated when the citations were broken out for each journal separately. The results of this analysis demonstrate the need to determine what resources constitute scholarly research and reflect the need for future researchers to consider the merits of each database before undertaking their research. This study will be of interest to scholars in library and information science as well as social work, as it facilitates a greater understanding of the strengths and limitations of each database and brings to light important considerations for conducting future research. 相似文献

The citation counts are increasingly used to assess the impact on the scientific community of publications produced by a researcher, an institution or a country. There are many institutions that use bibliometric indicators to steer research policy and for hiring or promotion decisions. Given the importance that counting citations has today, the aim of the work presented here is to show how citations are distributed within a scientific area and determine the dependence of the citation count on the article features. All articles referenced in the Web of Science in 2004 for Biology & Biochemistry, Chemistry, Mathematics and Physics were considered.We show that the distribution of citations is well represented by a double exponential-Poisson law. There is a dependence of the mean citation rate on the number of co-authors, the number of addresses and the number of references, although this dependence is a little far from the linear behaviour. For the relation between the mean impact and the number of pages the dependence obtained was very low. For Biology & Biochemistry and Chemistry we found a linear behaviour between the mean citation per article and impact factor and for Mathematics and Physics the results obtained are near to the linear behaviour. 相似文献

Many students struggle when citing sources in their research papers and have turned to web-based citation tools in increasing numbers. In order to test the accuracy of the citations generated by these products, a sample of student-selected electronic journal articles was collected and MLA and APA citations for these articles were created using EBSCO Discovery Service's Cite tool, EndNote Basic, RefWorks, and Zotero. Although EndNote Basic, RefWorks and Zotero's APA citation error rates were significantly lower than that of EBSCO Discovery Service, none of the programs was capable of generating an error-free MLA electronic journal citation. 相似文献

ABSTRACT The possibilities of the applications of the structure of bibliographical references in the proceedings of international scientific conferences for the management of information and library service are under discussion. On behalf of such research branches that do not have any specialized periodicals and which researchers are involved in other branches, too, it is demonstrated that the international scientific conference proceedings could be the only reliable source of references that adequately represent such branches and could be used for corresponding bibliometric studies. The results of the studies of disciplinary, chronological and species structures of references cited in the proceedings of the conferences in magnetic fluids and in bone marrow purging and processing are featured and discussed. Some results of detailed citation study of the citedness of particular authors are also presented. It is shown that the practice of taking into account the citation figures referring to only the first co-authors destroys the real picture of impact of individuals (in contrast to what Ferreiro, Ortega & Lara tried to demonstrate in 1977). The basic conclusion: there is a need in the bibliographical index of the proceedings of international scientific conferences of the citation index type. 相似文献

Prior research has suggested that providing free and discounted access to the scientific literature to researchers in low‐income countries increases article production and citation. Using traditional bibliometric indicators for institutions in sub‐Saharan Africa, we analyze whether institutional access to TEEAL (a digital collection of journal articles in agriculture and allied subjects) increases: (i) article production; (ii) reference length; and (iii) number of citations to journals included in the TEEAL collection. Our analysis is based on nearly 20,000 articles – containing half a million references – published between 1988 and 2009 at 70 institutions in 11 African countries. We report that access to TEEAL does not appear to result in higher article production, although it does lead to longer reference lists (an additional 2.6 references per paper) and a greater frequency of citations to TEEAL journals (an additional 0.4 references per paper), compared to non‐subscribing institutions. We discuss how traditional bibliometric indicators may not provide a full picture of the effectiveness of free and discounted literature programs. 相似文献

In citation network analysis, complex behavior is reduced to a simple edge, namely, node A cites node B. The implicit assumption is that A is giving credit to, or acknowledging, B. It is also the case that the contributions of all citations are treated equally, even though some citations appear multiply in a text and others appear only once. In this study, we apply text-mining algorithms to a relatively large dataset (866 information science articles containing 32,496 bibliographic references) to demonstrate the differential contributions made by references. We (1) look at the placement of citations across the different sections of a journal article, and (2) identify highly cited works using two different counting methods (CountOne and CountX). We find that (1) the most highly cited works appear in the Introduction and Literature Review sections of citing papers, and (2) the citation rankings produced by CountOne and CountX differ. That is to say, counting the number of times a bibliographic reference is cited in a paper rather than treating all references the same no matter how many times they are invoked in the citing article reveals the differential contributions made by the cited works to the citing paper. 相似文献

Traditionally, citation count has served as the main evaluation measure for a paper's importance and influence. In turn, many evaluations of authors, institutions and journals are based on aggregations upon papers (e.g. h-index). In this work, we explore measures defined on the citation graph that offer a more intuitive insight into the impact of a paper than the superficial count of citations. Our main argument is focused on the identification of influence as an expression of the citation density in the subgraph of citations built for each paper. We propose two measures that capitalize on the notion of density providing researchers alternative evaluations of their work. While the general idea of impact for a paper can be viewed as how many researchers have shown interest to a piece of work, the proposed measures are based on the hypothesis that a piece of work may have influenced some papers even if they do not contain references to that piece of work. The proposed measures are also extended to researchers and journals. 相似文献

In this paper we present a first large-scale analysis of the relationship between Mendeley readership and citation counts with particular documents’ bibliographic characteristics. A data set of 1.3 million publications from different fields published in journals covered by the Web of Science (WoS) has been analyzed. This work reveals that document types that are often excluded from citation analysis due to their lower citation values, like editorial materials, letters, news items, or meeting abstracts, are strongly covered and saved in Mendeley, suggesting that Mendeley readership can reliably inform the analysis of these document types. Findings show that collaborative papers are frequently saved in Mendeley, which is similar to what is observed for citations. The relationship between readership and the length of titles and number of pages, however, is weaker than for the same relationship observed for citations. The analysis of different disciplines also points to different patterns in the relationship between several document characteristics, readership, and citation counts. Overall, results highlight that although disciplinary differences exist, readership counts are related to similar bibliographic characteristics as those related to citation counts, reinforcing the idea that Mendeley readership and citations capture a similar concept of impact, although they cannot be considered as equivalent indicators. 相似文献

哪些因素会影响学术论文的被引次数是文献计量学领域的一个经典研究议题。目前的研究主要关注论文的内容特征和形式特征与被引次数之间的关系,鲜有研究从文本可读性视角切入这一议题。文本可读性影响读者对文本内容的理解和知识吸收,是一个关乎知识传播效率和研究成果认可度的重要因素。本研究在控制论文知识品质和权威性的基础上,使用文本可读性R值等五个变量研究论文的文本可读性对被引次数的影响。以中文图书情报学知名期刊发表于2016—2020年的论文为研究样本,研究发现论文的文本可读性R值、是否采用复合式标题、是否使用公式和表格对被引次数有显著影响,而是否使用图对被引次数没有显著影响。研究验证了中文情境下文本可读性对论文影响力的实质性作用,研究结果对科研人员改善自身的中文学术写作以及提高研究成果影响力具有重要参考价值。 相似文献
