Despite recent evidence that Microsoft Academic is an extensive source of citation counts for journal articles, it is not known if the same is true for academic books. This paper fills this gap by comparing citations to 16,463 books from 2013 to 2016 in the Book Citation Index (BKCI) against automatically extracted citations from Microsoft Academic and Google Books in 17 fields. About 60% of the BKCI books had records in Microsoft Academic, varying by year and field. Citation counts from Microsoft Academic were 1.5 to 3.6 times higher than from BKCI in nine subject areas across all years for books indexed by both. Microsoft Academic found more citations than BKCI because it indexes more scholarly publications and combines citations to different editions and chapters. In contrast, BKCI only found more citations than Microsoft Academic for books in three fields from 2013-2014. Microsoft Academic also found more citations than Google Books in six fields for all years. Thus, Microsoft Academic may be a useful source for the impact assessment of books when comprehensive coverage is not essential. 相似文献

学术图书是学者研究成果的集中体现。作者在写作过程中,参考、引证了大量文献,将这些被引文献析出即形成索引。因此,将精选学术图书作为来源文献,创建图书引文数据库是现实可行的。基于这一设想,并付之于实践,即形成了《中文图书引文索引》(CBkCI)。该数据库以精选学术图书作为来源文献(统计源),统计、分析图书作者引用图书、期刊论文、报告等所有文献资料的情况。CBkCI示范数据库的研制成功,不仅填补了国内在图书引文领域的空白,促进学术图书出版质量的提升,而且有助于图书馆进行图书采访,精选馆藏,并为学术评价提供坚实的基础。 相似文献

The aim of this study is to explore the phenomenon of research software citation and, in particular, to draw attention to the increasing importance of this form of citation in scholarly communication. This research sheds light on the current status of formal software citation that is captured by citation databases. Data for the study were gathered from more than 67,000 research software records available in public repositories indexed by Clarivate Analytics’ Data Citation Index (DCI). The metadata characteristics of the indexed records and citation data were then analyzed. Research software was rarely cited in the DCI, suggesting that the documented reuse of research software rarely occurs or is not well documented. Institutional repositories attracted few citations and had low rate of citation. It proved impossible, however, using the available data to isolate specific identifiers that can promote formal software citation. The findings presented here offer insights into research software citation that will be of interest to funding agencies, publishers, researchers, and research organizations. 相似文献

This paper examines the characteristics of 462 open access (OA) journals being published in India under the green, gold and hybrid models. The sample of journals was selected from DOAJ, IndianJournal.com and Open J‐Gate. Journal characteristics were measured in terms of growth, subjects, publishers, and citations under each model. While characteristics such as growth, subject, and publisher have been identified by exploring the journal's website only, the citation count of these journals has been calculated by using Google Scholar and the Indian Citation Index. The gold road is now the most popular form of OA publishing in the subcontinent. There is a great variation in the size of OA journals and in their publishers. One publisher has more than 77 journals, but 264 publishers publish a single journal only. Overall, the OA journal landscape is greatly influenced by a few key publishers and journals. While 43% of journals charge publication fees and the fees vary from as low as US$10 to as high as US$400, the highest impact factor of the gold OA journals has been noted as 0.58. The data presented here suggest that publication fees are not a major barrier to authorship within the fields of computer science, pharmacy, and medicine. 相似文献

Publishing articles in a prestigious journal is a golden rule for university professors and researchers nowadays. Impact factor, journal rank, and citation count, included in Science Citation Index managed by Thomson Reuters Web of Science, are the most important indicators for evaluating the quality of academic journals. By listing the journals encompassed in the “Integrative and Complementary Medicine” category of Science Citation Index from 2003 to 2013, this paper examines the publication trends of journals in the category. The examination includes number, country of origin, ranking, and languages of journals. Moreover, newly listed or removed journals in the category, journal publishers, and open access strategies are examined. It is concluded that the role of journal publisher should not be undermined in the “Integrative and Complementary Medicine” category. 相似文献

Multidisciplinary cooperation is now common in research since social issues inevitably involve multiple disciplines. In research articles, reference information, especially citation content, is an important representation of communication among different disciplines. Analyzing the distribution characteristics of references from different disciplines in research articles is basic to detecting the sources of referred information and identifying contributions of different disciplines. This work takes articles in PLoS as the data and characterizes the references from different disciplines based on Citation Content Analysis (CCA). First, we download 210,334 full-text articles from PLoS and collect the information of the in-text citations. Then, we identify the discipline of each reference in these academic articles. To characterize the distribution of these references, we analyze three characteristics, namely, the number of citations, the average cited intensity and the average citation length. Finally, we conclude that the distributions of references from different disciplines are significantly different. Although most references come from Natural Science, Humanities and Social Sciences play important roles in the Introduction and Background sections of the articles. Basic disciplines, such as Mathematics, mainly provide research methods in the articles in PLoS. Citations mentioned in the Results and Discussion sections of articles are mainly in-discipline citations, such as citations from Nursing and Medicine in PLoS. 相似文献

Online book reviews reflect readers’ attitudes and opinions and serve as a data source for book impact assessment. Most research has only focused on the number of ratings and reviews to assess the impact of books. However, it is necessary to more thoroughly explore online book reviews, to analyze the viewpoints and sentiments expressed in them and the identity and motivation of the reviewers in order to evaluate the value of different types of book reviews. In this study, we collect Goodreads reviews of books indexed by the Book Citation Index and consider them according to the following three aspects: the popularity of highly cited books in Goodreads, the influence of reviewer roles (of author, librarian, and ordinary user) on book reviews, and the emotions and opinions behind reviewers’ ratings. Results consider the number of books reviewed in different disciplines, the variations in ratings of highly cited and non-highly cited books, differences in book reviews given by the reviewer roles, and the way reviewers express their sentiments about the books. The study concludes that if online reviews are to be used as indicators of book impact assessment, key considerations should include the subject discipline, the reviewer's role, and the sentiment polarity. 相似文献

Dissertations can be the single most important scholarly outputs of junior researchers. Whilst sets of journal articles are often evaluated with the help of citation counts from the Web of Science or Scopus, these do not index dissertations and so their impact is hard to assess. In response, this article introduces a new multistage method to extract Google Scholar citation counts for large collections of dissertations from repositories indexed by Google. The method was used to extract Google Scholar citation counts for 77,884 American doctoral dissertations from 2013 to 2017 via ProQuest, with a precision of over 95%. Some ProQuest dissertations that were dual indexed with other repositories could not be retrieved with ProQuest-specific searches but could be found with Google Scholar searches of the other repositories. The Google Scholar citation counts were then compared with Mendeley reader counts, a known source of scholarly-like impact data. A fifth of the dissertations had at least one citation recorded in Google Scholar and slightly fewer had at least one Mendeley reader. Based on numerical comparisons, the Mendeley reader counts seem to be more useful for impact assessment purposes for dissertations that are less than two years old, whilst Google Scholar citations are more useful for older dissertations, especially in social sciences, arts and humanities. Google Scholar citation counts may reflect a more scholarly type of impact than that of Mendeley reader counts because dissertations attract a substantial minority of their citations from other dissertations. In summary, the new method now makes it possible for research funders, institutions and others to systematically evaluate the impact of dissertations, although additional Google Scholar queries for other online repositories are needed to ensure comprehensive coverage. 相似文献

The purpose of this research is to investigate the current state and trend of government website information cited by social science and humanities (SS&H) journal articles in China. The Chinese Social Science Citation Index (CSSCI) was used as the benchmark and the Social Science Citation Index (SSCI) journals as the reference samples. It analyzed 204,019 web citations (N = 5,063,237) found in 925,506 articles that were published in CSSCI journals during the 1998–2009 period. The findings unveil that web citations accounted for only 4.03% of the total number of citations (N = 5,063,237), and that citations of Chinese government websites constituted 6.6% of the total number of web citations (N = 204,019). The study disclosed detailed information regarding citations derived from ministries and commissions directly under the State Council websites (N = 69), government online media (N = 7), government website citation subjects (N = 21), and various types of government website information (N = 5). Although government website information has limited influence on SS&H, their impact is currently growing rapidly. In comparison with international research community, influence of government web information on Chinese social science is higher, while its influence on humanities is lower. Essentially, Chinese scholars put emphasis on citing information from authoritative central government websites or highly visible state-owned media information as supporting evidences in their articles. In general, the citation of information from Chinese government website tends to hot social issues of society. Finally, it is necessary to promote the visibility of local government websites, to develop policies and guidelines to encourage the disclosure and the diversity of data, so that there will be more citation balances between social and technological topics. 相似文献

The Emerging Sources Citation Index (ESCI) was created recently, in 2015, but few assessments of its journal coverage have been made. The present study tries to fill that gap by comparing its coverage with that of other international abstracting and indexing (A&I) databases. Using this measure, it is feasible to benchmark this index against the other citation indexes for acceptance criteria. We analysed 6,296 ESCI‐indexed journals, 8,889 Science Citation Index Expanded (SCIE), 3,258 Social Science Citation Index (SSCI), 1,784 Arts and Humanities Citation Index (AHCI), and 22,749 Scopus journals as indexed in July 2017 to determine their inclusion in 105 databases. We found that 19.3% of the ESCI journals are not covered by any other A&I databases, a high figure compared with only 0.5% SCIE, 0.3% SSCI, 0.3% AHCI, and 5.5% Scopus journals. This low coverage suggests that the selection criteria for ESCI journals are not consistent with the overall trend in the other classical citation indexes. 相似文献

合理利用SCI对个人做学术评价 总被引：10，自引：0，他引：10
对个人进行学术评价时，《科学引文索引》提供该作者的论文数目，刊登论文的期刊影响因子，以及论文发表后被引次数等各种信息，本文作者认为三者虽说都应考虑，但后二者尤为重要，同时这些统计数字非神圣不可侵犯，因为学科之间千差万别，缺乏互比性，有些成果开创性强，来之不易，但被引次数反而不如沿着前人指引方向获得的后续成果，因此，同行评议还是需要的。 相似文献

The impact of monographs in a vertebrate zoology collection on the scientific literature was assessed using a randomly selected sample (52 monographs), Science Citation Index and a statistical package. Characterstics of the monographs considered were: copyright date, circulation, citation frequency and subdiscipline (ichthyology, herpetology, ornithology, mammalogy). Citing references were dispersed among journals in a wide array of disciplines. A few monographs proved to be very highly cited (one being cited nearly 600 times), and so generated the majority of the database of 2,971 citations. The ichthyology monographs generated the broadest subject dispersion among citing references. The herpetology collection is less active than are the others in terms of circulation and current citation frequency. The sample has been generating an ever increasing share of the citations in the Science Citation Index. A method that applies citation analysis to the evaluation of monograph collections is outlined. 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
