Altmetrics国内外研究中的问题与挑战 总被引：1，自引：0，他引：1
[目的/意义]试图了解当前Altmetrics研究中的主要问题与亟待应对的挑战。[方法/过程]采用文献回顾的方法,对国内外Altmetrics研究进行系统的梳理和分析。[结果/结论]提出Altmetrics的理论研究需要面对定义模糊、研究方法和对象的独特性不足、理论基础缺乏、行为层面的理解较少等4个方面的问题,而应用研究需要面对指标覆盖率低、有偏、易为操纵和异质等4个方面的问题。作为科学计量学中最热门的新兴研究领域,当前Altmetrics研究中的诸多问题与挑战并不会贬损其价值,而是为我们提供了开展深入研究的空间。 相似文献

[目的/意义]通过分析某个学科领域中Altmetrics指标的特征,为该领域文献影响力评价提供更加科学合理的指标体系。[方法/过程]定位于图书情报领域,选取Scopus、Altmetric.com进行文献被引频次及Altmetrics指标值的采集,对数据进行统计分析、聚类分析和内容分析。[结果/结论]在众多Altmetrics指标中,Mendeley和Twitter更适合于对图书情报领域文献的影响力做出评价;Mendeley和Twitter中文献的使用群体、文献主题、内容和期刊分布都存在明显的差异性;Twitter适合对文献的社会影响力做出判断,Mendeley更适用于文献的学术影响力评价;不同工具的流行程度存在地域差异,利用Altmetrics指标时应考虑该指标对文献影响力的评价是否存在地域缺失。 相似文献

作为衡量新型影响力的计量方法,Altmetrics的出现引起了科技评价领域的广泛讨论。研究影响高Altmetrics指标论文的特征因素及其演变情况,可为合理使用Altmetrics指标提供借鉴,为发展和完善Altmetrics计量方法提供参考。因此,本文选取Altmetric Top 100论文作为研究样本,对比分析2013-2018年6年的高Altmetrics指标论文的时间分布、期刊分布、研究领域分布以及多源指标贡献度的演变情况。研究结果表明,高Altmetrics指标论文的网络关注度大体上逐年上升,并主要发表在Nature、Science、PNAS等10种高影响力期刊上,分布于医学健康科学、生物科学等8个研究领域。在多项Altmetrics指标中,News、Blogs以及Twitter表现出显著优势。 相似文献

[目的/意义]为了探讨在学科论文评价上,Altmetrics指标间的量度结果是否具有一致性,试图通过已有测量数据构建基于Altmetrics的文献综合评价模型,为评价数据的使用和重用创建新的度量标准。[方法/过程]获取PLoS ALMs上土木工程学科2009年至2016年发表的全部文章的Altmetrics指标,采用相关分析、主成分分析方法将15个原始指标划分到4个主成分,得到适用于具体学科的Altmetrics评价指标体系,并对Altmetrics的单一指标与综合评价指标进行相关度分析,采用"公平性测试"方法探索时间对论文评价相关度的差异。[结果/结论]研究发现采用"公平性测试"方法消除时间影响后,引用指标相关性上升,而与社交媒体传播相关的指标有所下降,但Twitter指标不降反增,且始终与F值具有较高的相关性。 相似文献

开放科研环境下，科研成果的产出形式及传播方式都发生了变化，而与之相适应的科研成果评价方式也呈现出多元趋势。Altmetrics基于学术社交网络及开放存取平台提取的社会评价指标，对全面评价科研成果社会影响力提供了重要参考，但由于Altmetrics自身的特点在科研成果评价中需要谨慎的使用。文章在阐述Altmetrics理论背景的基础上，依据Altmetrics指标来源归纳了Altmetrics指标类型，并在分析Altmetrics优劣势的基础上从辩证思维视角对Altmetrics在科研成果评价中的应用提出建议。 相似文献

论推动替代计量学发展的若干基本问题 总被引：6，自引：5，他引：1
替代计量学快速发展,同时也造成了一些困扰,主要表现在替代计量学的研究内涵存在争议,替代计量指标内在价值不够明朗,替代计量指标可信度遭到质疑。本文对近年来替代计量学的研究论著进行追踪和梳理,利用狭义、广义二分法归纳替代计量学的研究内涵,明确提出狭义的替代计量学专门研究相对传统引文指标的在线新型计量指标及其应用,广义的替代计量学研究在线新型科学交流体系和面向学术成果的全面影响力评价指标体系。若根据应用情境对替代计量指标和数据源进行细分,既能反映学术成果的社会影响力,也能反映学术成果的学术影响力。从规避数据操纵、数据严谨性和数据一致性三个方面,论证了替代计量指标具备实用的可信度。替代计量学研究有利于增加发展中国家科学家的话语权,对创新型科学交流机制起到促进作用。对应Altmetrics这个英文术语,"替代计量学"是最合适的中文译名。 相似文献

[目的/意义]提出用“社交媒体计量学”这一术语概括以社交媒体信息为逻辑起点的系列计量研究的构想,并论述在Altmetrics逐渐发展成熟的背景下提出社交媒体计量学的必要性。[方法/过程]梳理社交媒体的定义、特点和类型,介绍Altmetrics诞生前和发展过程中产生的相关术语概念,界定社交媒体计量学的概念与研究内容,同时分析比较社交媒体计量学与Altmetrics之间的相互关系,分别从对Altmetrics和对计量学科整体发展作用的角度论证用“社交媒体计量学”这一术语概括以社交媒体信息为逻辑起点的系列计量研究的科学性、客观性和合理性。[结果/结论 ]社交媒体计量学是在以社交媒体为场景的网络环境下呼之欲出的计量学分支学科,它围绕社交媒体这一新的信息载体,研究社交媒体用户之间及其与科学信息的交互特征与规律,从而提炼社交媒体信息的科学价值。这一术语的提出能够为社交媒体相关计量研究尤其是国内研究开辟新的研究思路,从而促进学科整体发展。 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers. 相似文献

ABSTRACTGerman authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

Most studies of collection development mask inadequate theoretical underpinnings with facile assumptions and dazzling statistical manipulations. This essay, in moving toward a model for collection development within both specific collections and library systems as a whole, seeks to demonstrate the full range and complexity of relevant factors. An enlarged theoretical grasp should help highlight both the possibilities and the challenges of existing approaches. One result could be a shift toward gaming or simulation techniques as more realistic analytical tools. 相似文献

An annotated list is presented describing seventeen periodicals that cover significant aspects of the gay, lesbian, bisexual, and transgender (GLBT) community and their culture in whole or in part, with popular content rather than an academic or research focus. The titles included are a selective and representative sampling. The entry for each periodical includes the following information: periodical title, publisher/editor and address, basic information, publication data, content, Internet information, an abstract/annotation, and evaluative statement 相似文献

SUMMARY The Nevada Constitution provides voters with the ability to propose new statutes, amendments to existing statutes, and amendments to the State constitution through the initiative petition process. Voters can also approve or disapprove of existing statutes through the referendum petition process. Both require the circulation of a petition to collect a minimum number of signatures before the Secretary of State will place the measures on the ballot for the general election. As with other topics of law, Nevada has a profound shortage of research resources on initiatives and referenda, but State law and government Web sites provide enough information to allow for significant research. 相似文献
