Author ranking evaluation at scale     

Marcel Dunaiski  Jaco Geldenhuys  Willem Visser 《Journal of Informetrics》2018,12(3):679-702

We evaluate author impact indicators and ranking algorithms on two publication databases using large test data sets of well-established researchers. The test data consists of (1) ACM fellowship and (2) various life-time achievement awards. We also evaluate different approaches of dividing credit of papers among co-authors and analyse the impact of self-citations. Furthermore, we evaluate different graph normalisation approaches for when PageRank is computed on author citation graphs.We find that PageRank outperforms citation counts in identifying well-established researchers. This holds true when PageRank is computed on author citation graphs but also when PageRank is computed on paper graphs and paper scores are divided among co-authors. In general, the best results are obtained when co-authors receive an equal share of a paper's score, independent of which impact indicator is used to compute paper scores. The results also show that removing author self-citations improves the results of most ranking metrics. Lastly, we find that it is more important to personalise the PageRank algorithm appropriately on the paper level than deciding whether to include or exclude self-citations. However, on the author level, we find that author graph normalisation is more important than personalisation.  相似文献   

A quantitative and model-driven approach to assessing higher education in the United States of America     

Zuqing Huang 《Quality in Higher Education》2016,22(1):78-95

University ranking or higher education assessment in general has been attracting more and more public attention over the years. However, the subjectivity-based evaluation index and indicator selections and weights that are widely adopted in most existing ranking systems have been called into question. In other words, the objectivity and impartiality of those rankings has been worrisome. To address these concerns, this paper presents a quantitative and model-driven approach to acquiring the evaluation index and indicator weights in the US News & World Report ranking system. Structural equation modelling will be applied to mine non-subjective weights from collected data. The proposed approach will be validated using two groups of United States universities, National Universities and Liberal Arts Colleges, classified by the US News & World Report. Managerial and administrative implications will also be explored. This study shows a very promising future because it opens a new venue for the scholars and practitioners in the higher education assessment field to develop a real-time, scalable and model-driven higher education ranking system.  相似文献   

我国大学排行研究与实践的进展及评析   总被引：5，自引：0，他引：5  

谢安邦  童康 《高等教育研究》2006,(6)

大学排行在传统上属于社会评估范畴。近年来,由于多主体的参与与高校改革,大学排行的传统概念与实践逐渐发生着变化。大学排行应该围绕“大学发展”的核心指标展开,构建大学发展性排行指标与评估体系。因为只有大学发展了,才能满足多方需求,更好地实现大学排行多种功能。  相似文献

我国大学排名研究综述     

李文兵 《高教发展与评估》2007,23(4):29-36

20世纪90年代以来,我国的大学排名活动开展得有声有色,在国内甚至国际有一定影响的大学排名已经有5家。大学排名活动已经成为我国高校评估领域一支不可忽视的力量。同时,对大学排名的研究工作也一直没有停止过。各种有关大学排名的研究文章也构成了高等教育研究中的一个小热点。对有关文章的各种观点从比较、作用、质疑和建议等四个方面进行理论梳理与归纳总结。  相似文献   

"有没有VP"与"VP没有"的比较研究     

马春华 《洛阳工业高等专科学校学报》2005,15(1):94-96

一种新句式叙述性“有没有VP”的出现,势必对普通话句式的格局产生一定的影响。它与普通话传统用语“VP没有”都是选择问句,表达的基本意义相近,使用时,人们往往把这两种形式看成是完全等同的。本文着眼于这两种句式的“微殊”,试从形成模式、问话期待、语义重心和回答方式、句式特点和变换方式上作一些探讨,以期更好地指导人们的言语实践。  相似文献   

Building parallel corpora by automatic title alignment using length-based and text-based approaches     

Christopher C. Yang  Kar Wing Li 《Information processing & management》2004,40(6):27

Cross-lingual semantic interoperability has drawn significant attention in recent digital library and World Wide Web research as the information in languages other than English has grown exponentially. Cross-lingual information retrieval (CLIR) across different European languages, such as English, Spanish, and French, has been widely explored; however, CLIR across European languages and Oriental languages is still in the initial stage. To cross language boundary, corpus-based approach is promising to overcome the limitation of the knowledge-based and controlled vocabulary approaches but collecting parallel corpora between European language and Oriental language is not an easy task. Length-based and text-based approaches are two major approaches to align parallel documents. In this paper, we investigate several techniques using these approaches and compare their performances in aligning English and Chinese titles of parallel documents available on the Web.  相似文献   

Jointly valuing journal visibility and author citation count: An axiomatic approach     

《Journal of Informetrics》2020,14(1):100988

This paper proposes a simple, flexible, axiom-based mechanism for facilitating the comparison between a scholar's citation count and the visibility of the journals wherein the scholar's articles were published. The goal is to help research review bodies easily grasp the distinction these two forms of scholarly accomplishment and to provide a transparent way to articulate expectations about them to scholars. The approach is demonstrated using a widely applied and cooperative functional form that can reflect, via different parameter values, a wide range of possible beliefs about the relative merits of citation counts and journal visibility.  相似文献   

论高等教育学生资助对象的认定     

贺保月 《南阳师范学院学报》2011,10(4):116-121

高等教育产品属于准公共产品,但各层次、各类别高校、各专业产品公共性是有区别的。个人高等教育选择依据其高等教育的私人产品性质而做出,在现有中国高等教育入学选拔制度下,最能反映高等教育私人产品性质的是各高校及专业选择性指标的高低,这可以从报考志愿拥挤度和录取分数得以反映。高等教育学生资助,首先应依据申请学生所在学校、专业的选择性指标对学生进行分类,实施以政府资助为主或是以市场、学校资助为主。其次应对贫困学生进行分级,学生学习生活每月消费支出（参考最低生活保障标准）、所学专业类型、家庭所在位置（城乡、区域）、学生交纳学费情况、家庭成员职业背景、家庭或成员特殊情况等指标最能反映经济困难程度,应根据这些指标计算出个体的贫困指数,对资助主体实施不同级别的资助。再次应完善学生资助对象认定路径,要加大非诚信者的机会成本、建立资助信息平台、完善市场化资助主体认定资助对象的相关政策、细化资助对象认定的具体措施。  相似文献
