New types of calculation methodologies, called altmetrics, which is short for alternative metrics, are increasingly being used to measure and analyze the scholarly communication networks of researchers, librarians, publishers, and funding organizations. By applying altmetrics to emergent online forums like Twitter, Academia.edu, Mendeley, and ResearchGate, studies have shown that early measures of social attention to a work or body of work can be correlated with later usage and citation statistics to predict the diffusion and impact of research output. However, standards for altmetrics are needed to build confidence and trust among the information community.  相似文献

Information about faculty and their publications can be found in library databases such as the Library of Congress Name Authority File, VIAF, WorldCat, and institutional repositories; in identifier registries such as ORCID and ISNI; and on academic social networking sites such as Academia, Google Scholar, and ResearchGate, but the way search engines use such identifiers and profiles is unclear. Therefore, researchers at a large comprehensive university conducted several rounds of web searching before and after the creation and modification of faculty authority records. The sample consisted of 24 faculty and the 35 publications associated with their authorities. The researchers searched for the faculty and their publications on the social networking and identity websites directly, and then used Google, Bing, and Google Scholar to record which of the faculty members’ profiles and publications were found within the top 50 results. Faculty with more profiles were more visible in search engine results, and faculty with authority records ranked more highly in Google. Results related to publication discovery and ranking were more inconclusive, but revealed clear differences between search tools. The implications of this exploratory research can support educational efforts about academic identities and scholarly profiles, begin a research agenda, and inform methodological development surrounding the influence of identity records and academic social networking profiles on web visibility.  相似文献

This article presents findings from the first year of the Harbingers research project started in 2015. The project is a 3‐year longitudinal study of early career researchers (ECRs) to ascertain their current and changing habits with regard to information searching, use, sharing, and publication. The study recruited 116 researchers from seven countries (UK, USA, China, France, Malaysia, Poland, and Spain) and performed in‐depth interviews by telephone, Skype, or face‐to‐face to discover behaviours and opinions. This paper reports on findings regarding discovery and access to scholarly information. Findings confirm the universal popularity of Google/Google Scholar. Library platforms and web‐scale discovery services are largely unmentioned and unnoticed by this user community, although many ECRs pass through them unknowingly on the way to authenticated use of their other preferred sources, such as Web of Science. ECRs are conscious of the benefits of open access in delivering free access to papers. Social media are widely used as a source of discovering scholarly information. ResearchGate is popular and on the rise in all countries surveyed. Smartphones have become a regularly used platform on which to perform quick and occasional searches for scholarly information but are only rarely used for reading full text.  相似文献

Today, it is not clear how the impact of research on other areas of society than science should be measured. While peer review and bibliometrics have become standard methods for measuring the impact of research in science, there is not yet an accepted framework within which to measure societal impact. Alternative metrics (called altmetrics to distinguish them from bibliometrics) are considered an interesting option for assessing the societal impact of research, as they offer new ways to measure (public) engagement with research output. Altmetrics is a term to describe web-based metrics for the impact of publications and other scholarly material by using data from social media platforms (e.g. Twitter or Mendeley). This overview of studies explores the potential of altmetrics for measuring societal impact. It deals with the definition and classification of altmetrics. Furthermore, their benefits and disadvantages for measuring impact are discussed.  相似文献

The article reports on a systematic method of undertaking a literature search on the educational impact of being a young carer (16–24 years old). The search methodology applied and described in detail will be of value to academic librarians and to other education researchers who undertake systematic literature searches. Seven bibliographic databases and Google Scholar were searched between November 2015 and January 2016. Two and three concept search structures were compared, involving 28 search terms plus truncation variants. One hundred and eighty-one relevant articles were retrieved. Sensitivity, precision, and “unique articles retrieved” were used as metrics. Social Care Online and Google Scholar had the greatest sensitivity. As well as meticulous use of AND, OR, and bracket operators, the use of NEAR and NOT operators to increase precision were tested and are recommended as useful tools for conducting systematic searches.  相似文献

This research study evaluates the quality of articles published by Saudi and expatriate authors in foreign Library and Information Science (LIS) journals using three popular metrics for ranking journals—Journal Impact Factor (JIF), SCImago Journal Rank (SJR), and Google Scholar Metrics (GSM). The reason for using multiple metrics is to see how closely or differently journals are ranked by the three different methods of citation analysis. However, the 2012 JIF list of journals is too small, almost half the size of the SJR and GSM lists, which inhibited one-to-one comparison among the impact factors of the thirty-six journals selected by Saudi authors for publishing articles. Only seventeen journals were found common to all the three lists, limiting the usefulness of the data. A basic problem is that Saudi LIS authors generally lack the level of competency in the English language required to achieve publication in the most prominent LIS journals. The study will have implications for authors, directors, and deans of all types of academic libraries; chairmen and deans of library schools; and the Saudi Library Association. Hopefully these entities will take necessary steps to prepare and motivate both academics and practicing librarians to improve the quality of their research and publications and thus get published in higher ranked journals.  相似文献

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

A qualitative study of the impact of electronic journals on the information behavior of academic researchers at Catalan universities shows that academic researchers now read more, and more widely. However, their reading is becoming more superficial; they are compelled to improve their discrimination skills in order to decide what to read in more depth. The electronic accessibility of journals means that researchers now make fewer library visits. Web browsing and table of contents (TOC) e-mail alerts are replacing physical browsing, and searching is a very popular option for keeping up to date with developments. Internet search engines, especially Google and Google Scholar, are becoming important sources of information for researchers. However, they face problems in managing their personal scientific information.  相似文献

The article reports on a study of the views and actions of nearly a hundred scholars – mostly academic researchers from four European countries and four disciplines – in regard to scholarly reputation in the Science 2.0 age. It specifically looks at the role that 'emerging reputational mechanisms and platforms are playing in building, maintaining, and showcasing scholarly reputation in the digital age. Popular examples of such platforms are ResearchGate and Academia.edu . Data were obtained through one‐to‐one interviews and focus groups, supported by desk research. The main findings were: (a) it is early days and uptake is light and patchy with platforms largely used for non‐reputational purposes, such as sharing documents; (b) most users were passive and did not fully engage with the social aspects of the platforms; (c) the reputational focus was very much on just one scholarly activity (research), on just two outputs of that activity (publications and conferences) and one measurement of that activity (citations), but there are the stirrings of change; (d) young researchers are set to profit most from the emerging platforms.  相似文献

ABSTRACT

Almost three years after Google Scholar's inception, only a third of Ohio Library and Information Network (OhioLINK) member libraries link to it from their Web sites. This article reports the results of a July 2007 survey of OhioLINK academic librarians, conducted to find out about their attitudes and current practices regarding promotion of Google Scholar. It compares the findings about placement of Google Scholar on Web sites and inclusion in library instruction with previous research, and includes recommendations for libraries about Google Scholar.  相似文献

While ResearchGate has become the most popular academic social networking site in terms of regular users, not all institutions have joined and the scores it assigns to academics and institutions are controversial. This paper assesses the presence in ResearchGate of higher education institutions in Europe and the US in 2017, and the extent to which institutional ResearchGate Scores reflect institutional academic impact. Most of the 2258 European and 4355 US higher educational institutions included in the sample had an institutional ResearchGate profile, with near universal coverage for PhD-awarding institutions found in the Web of Science (WoS). For non-PhD awarding institutions that did not publish, size (number of staff members) was most associated with presence in ResearchGate. For PhD-awarding institutions in WoS, presence in RG was strongly related to the number of WoS publications. In conclusion, a) institutional RG scores reflect research volume more than visibility and b) this indicator is highly correlated to the number of WoS publications. Hence, the value of RG Scores for institutional comparisons is limited.  相似文献

Academic genealogy aims to structure and analyze the mentoring relationships between advisor and advisee. The representation of this structure results in academic genealogy graphs. For the analysis and characterization of these graphs, we present a set of metrics and their corresponding mirror metrics that capture the characteristics of its topological structure and represent them as quantitative attributes. The metrics of fecundity, fertility, descendants, cousins, generations, and relationships consider the descendants of the academics represented in the graph. The mirror metric of these topological metrics considers the ascendancy of academics. Individually, the metrics have strong semantic intuition and define characteristics regarding the performance in the mentoring of an academic. Together, the metrics are useful for the identification, characterization, and classification of communities and their members. The genealogical data available through the platforms of the Mathematics Genealogy Project and the Academic Family Tree were used as case studies. Two hundred thirteen thousand and 675,000 academic records were obtained for each project. We analyze the capacity of characterization of the metrics using the structuring of a similarity graph and through the distribution of the nodes in principal components. We observed that the set of metrics is capable of capturing the configuration pattern existing in genealogy graphs independently of its scale.  相似文献

ABSTRACT

A primary impact metric for institutional repositories (IR) is the number of file downloads, which are commonly measured through third-party Web analytics software. Google Analytics, a free service used by most academic libraries, relies on HTML page tagging to log visitor activity on Google's servers. However, Web aggregators such as Google Scholar link directly to high value content (usually PDF files), bypassing the HTML page and failing to register these direct access events. This article presents evidence of a study of four institutions demonstrating that the majority of IR activity is not counted by page tagging Web analytics software, and proposes a practical solution for significantly improving the reporting relevancy and accuracy of IR performance metrics using Google Analytics.  相似文献

The literature shows that students are more likely to begin their search via Google, as it is perceived to be easier and more accessible than other databases or publisher platforms. The invisible web, specifically publisher platforms, is sometimes too difficult for students to access; there are also suggestions that Google Scholar in particular may outperform other paid-for databases. The ease of access and the somewhat misguided notion that Google Scholar has more reliable information than that provided by libraries makes search engines all the more attractive. This culture of searching using a single search box is reflected in the increase in the number of libraries opting for single resource discovery systems such as Summon or Primo, which use a single search covering all the library holdings. The findings suggest that whilst Google Scholar can perform well in some circumstances, it performed only moderately well when compared with LISTA and Summon – the single resource discovery system tested. It was the least successful resource in terms of precision when compared with LISTA, Summon, Emerald and Sage. However, the simplicity of search engines begs the question: will databases and publisher platforms become obsolete? The study concludes that subject specific databases are more effective than search engines, but the complexity of accessing the invisible web is hindering their popularity.  相似文献
