邱均平  张心源  董克 《图书情报工作》2015,59(2):100-105

[目的/意义]鉴于目前机构知识库的相关研究主要集中在理论、技术支持和平台建设等方面,欠缺对机构知识库质量控制与内容评价的有效方式的研究,利用Altmetrics可以弥补传统计量学方法评价和机构知识库质量控制方面的不足。[方法/过程]根据机构知识库的特点,从机构知识库整体、特定资源和发布者角度提出可用于机构知识库评价的Altmetrics指标;依据不同的机构知识库开发平台系统,归纳总结其所具有的Altmetrics功能,并进一步结合实例进行分析。[结果/结论]总结国内机构知识库建设发展的情况及其现有的评价指标,发现传统评价指标可以与Altermetrics指标互相补充,认为Altermetrics在机构知识库的应用具有良好的发展前景。  相似文献

An approach for the capture of context-dependent document relationships extracted from Bayesian analysis of users' interactions with information     

D. R. Campbell  S. J. Culley  C. A. McMahon  F. Sellini 《Information Retrieval》2007,10(2):115-141

A number of technologies exist which enable the unobtrusive capture of computer interface interactions in the background of a user's working environment. The resulting data can be used in a variety of ways to model aspects of search activity and the general use of electronic documents in normal working routines. In this paper we present an approach for using captured data to identify relationships between documents used by an individual or group, representing their value in a given context—that may relate to specific information need or activity. The approach employs the use of a naïve Bayesian classifier to evaluate possible relationships that are derived implicitly from the data. It is intended that the relationships established be stored within an information retrieval (IR) system to aid in the retrieval of related documents where future users arrive at a similar context. In the evaluation of the approach over 70 hours of data from computer users in industrial and academic settings are collected to assess its overall feasibility. The results indicate that the approach provides a useful method for the establishment of identifiable relationships between documents based on the context of their usage, rather than their content.  相似文献

Performance Funding Programs: Assessing Their Stability     

Burke  Joseph C.  Modarresi  Shahpar 《Research in higher education》2001,42(1):51-70

State programs of performance funding for public colleges and universities are both popular and volatile. A previous article identified some characteristics of stable programs by comparing the survey responses of state and campus leaders from Tennessee and Missouri about their mature programs with those from four states that later dropped performance funding. This article uses those characteristics to assess the stability of the continuing programs in Florida, Ohio, and South Carolina. This article compares the survey responses of state and campus leaders from each of these three states about their programs with those from Missouri and Tennessee. The findings suggest trouble for these three programs, for they share few of the characteristics common to the stable programs in Missouri and Tennessee.  相似文献   

Critical rationalism and the search for standard (field-normalized) indicators in bibliometrics     

Lutz Bornmann  Werner Marx 《Journal of Informetrics》2018,12(3):598-604

Bibliometrics plays an increasingly important role in research evaluation. However, no gold standard exists for a set of reliable and valid (field-normalized) impact indicators in research evaluation. This opinion paper recommends that bibliometricians develop and analyze these impact indicators against the backdrop of Popper’s critical rationalism. The studies critically investigating the indicators should publish the results in such a way that they can be included in meta-analyses. The results of meta-analyses give guidance on which indicators can then be part of a set of indicators used as standard in bibliometrics. The generation and continuous revision of the standard set could be handled by the International Society for Informetrics and Scientometrics (ISSI).  相似文献   

PlumX评价指标对促进中国科技期刊国际传播的启示     

丁佐奇 《编辑学报》2018,30(6):610-612

利用各种社交网络平台,进行科学论文的获取、分享与传播已成为当前学术交流的重要形式,为此研究社交网络对科技期刊国际传播的影响。利用Elsevier数据库整合的替代计量学指标PlumX,分析PlumX与论文被引频次的关系及其学术特征。基于《中国天然药物》单刊及药理学/毒理学学科分析,均发现高被引论文的PlumX评分显著高于低被引论文,且学科高被引论文的被引频次和PlumX评分呈正相关,此外,高质量的综述和国际论文更易获得社交网络关注。研究结果发现PlumX指标能够对单篇论文的学术影响力进行快速评价,非国际权威期刊中的热点论文也可能获得较高关注,指出英文科技期刊应重视约组社交网络平台发达和应用广泛的相关主流国家优秀稿件,合理利用社交网络平台有助于获得较高的PlumX评分,进而提升发展中国家科学家的话语权。  相似文献

Identification of innovating firms through technological innovation indicators: an application to the Spanish ceramic tile industry   总被引：1，自引：0，他引：1  

M.L Flor 《Research Policy》2004,33(2):323-336

The identification of technologically innovating firms is related to the development of indicators of their innovation activity. In this study, we carry out a review of indicators of firms’ technological innovation activity and then classify them according to whether they are based on inputs or outputs of the innovation process, and to the sources of the information they consider, whether primary or secondary. Their applicability as indicators of firm innovation is analyzed in the Spanish ceramic tile industry for the period from 1994 to 1996. From the results obtained we are able to conclude that the method based on direct information—self-assessment by managers—is more effective in identifying both product and process innovators. Within the set of methods based on secondary information, the literature-based innovation output (LBIO) method is the one which provides the best results when identifying product innovators alone.  相似文献
