This article presents the results of a comparative study of Web of Science (WoS), Scopus, and Google Scholar (GS) for a set of 15 business and economics journals. Citations from the three sources were analyzed to determine whether one source is better than another, or whether a new database such as Scopus, or a free database such as GS could replace WoS. The authors concluded that scholars might want to use alternative tools collectively to get a more complete picture of the scholarly impact of an article.  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

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage.  相似文献

This paper examined the citation impact of Chinese- and English-language articles in Chinese-English bilingual journals indexed by Scopus and Web of Science (WoS). Two findings were obtained from comparative analysis: (1) Chinese-language articles were not biased in citations compared with English-language articles, since they received a large number of citations from Chinese scientists; (2) a Chinese-language community was found in Scopus, in which Chinese-language articles mainly received citations from Chinese-language articles, but it was not found in WoS whose coverage of Chinese-language articles is only one-tenth of Scopus. The findings suggest some implications for academic evaluation of journals including Chinese-language articles in Scopus and WoS.  相似文献

A researcher's Q denotes their ability in scientific research as a real number. Due to their short presence in the academic environment, junior researchers have unstable Q values. This article aims to present a model that uses data from junior researchers’ first years of publication to predict their stable Q values. We tested the deep model and the linear regression model and compared their accuracies. We have obtained reliable results showing that the predicted values estimated with both models are better than the estimated Q values computed with the Q model itself when using only data from the first five years of publication. Lastly, we note that both approaches are robust approaches to deal with the inflation of citation bias.  相似文献

A method was developed to rank journals in a specific subject area, molecular and cellular biology (MCB), in order to create a core list of journals for the MCB faculty of the Pennsylvania State University. The core list of journals was needed as the first step in a larger serials evaluation process. The method did not require use data, but incorporated various quality measures, including publication in journals by Penn State faculty, citings of journals by Penn State faculty, and Journal Citation Report data from ISI. This study produced a core list of 50 MCB journals, as well as other benefits. Although the list of core MCB journals derived from this study is specific to the needs of Penn State faculty, the method could be adapted to other situations.  相似文献

从1918年中国大陆学者开始在SCI/SSCI来源期刊发表法学论文算起,中国大陆学者参与国际法学研究历程已近百年,产生了大量的研究成果.以Web of Science平台中收录的中国大陆学者参与的法学文献为来源,从文献增长规律、核心作者群体、核心期刊分布及及关键词分布四个维度进行文献计量分析.结果表明:中国大陆学者参与发表的国际法学文献主要集中在经济贸易、互联网、环境保护及知识产权方面,而对农村、医疗、青少年等法律问题关注较少,该领域的研究并未形成核心作者群体和核心期刊群体.  相似文献

The study investigated how three agencies in Sweden were pursuing the implementation of an electronic archive (e-archive). The e-archive was seen by the Swedish National archives as a pre-requisite to the effective management of government information and would help the agencies to comply with the Swedish Public Sector Information (PSI) law which requires them to publish open data. It was also seen as an important component of an efficient e-government. The study further had two objectives: to establish whether the common specifications were being used and how the implementation of the PSI-law was being pursued. Interviews and a literature review were used as data gathering techniques. The Records Continuum Model (RCM) was applied to enhance an understanding of how the agencies were dealing with the publication of open data. Two of the agencies had implemented an e-archive but the third agency lacked one. All the three were publishing open data. The agency that did not have an e-archive was publishing open data that suited its existing information management infrastructure. This has implications since the PSI-law requires full publication of all PSI which has no restrictions. The common specifications were not being used by the agencies.  相似文献

The paper considers how attributes and skills fundamental to the information profession may be applied to the development and management of Web-based services and resources. It also looks at the need for the acquisition of new skills as part of a continuing professional development programme. The report considers the changing role of the Webmaster and the implications this might have in terms of the role of information professionals. To offer a practical example, from within the healthcare sector, the article goes on to describe the development of BMA Library Online. This is the BMA Library's own suite of Web-based information services and resources for personal members, institutional members and staff. The library's own Web team has been responsible for the development and maintenance of BMA Library Online. To conclude, the paper looks forward to future possibilities for information professionals as Web developers and at how this might be influenced by changes in the Webmaster role. It is crucial that skills and expertise are shared as the roles that go to make up a Webmaster or Webmaster team continue to merge and evolve, and with the possible wider distribution of provision of Web content within organizations.  相似文献
