A comparative study on world university rankings: a bibliometric survey

Recently there are many organizations conducting projects on ranking world universities from different perspectives. These ranking activities have made impacts and caused controversy. This study does not favor using bibliometric indicators to evaluate universities?? performances, but not against the idea either. We regard these ranking activities as important phenomena and aim to investigate correlation of different ranking systems taking bibliometric approach. Four research questions are discussed: (1) the inter-correlation among different ranking systems; (2) the intra-correlation within ranking systems; (3) the correlation of indicators across ranking systems; and (4) the impact of different citation indexes on rankings. The preliminary results show that 55?% of top 200 universities are covered in all ranking systems. The rankings of ARWU and PRSPWU show stronger correlation. With inclusion of another ranking, WRWU (2009?C2010), these rankings tend to converge. In addition, intra-correlation is significant and this means that it is possible to find out some ranking indicators with high degree of discriminativeness or representativeness. Finally, it is found that there is no significant impact of using different citation indexes on the ranking results for top 200 universities.

A bibliometric tale of two cities: Hong Kong and Singapore

A research evaluation of the leading research universities globally using the curated bibliometric data from Shanghai Rankings Global Ranking of Academic Subjects 2018 shows Hong Kong at the top position. A X/GDP productivity criteria is used where each country’s scientific wealth is represented by X, a second-order bibliometric indicator, and its nominal Gross Domestic Product (GDP) is taken as a measure of its economic wealth. Singapore appears at the fifth position. This brief communication looks at the anatomy of this exceptional performance of the two city states, which are similar in many ways and yet dissimilar in many other ways. Hong Kong has the slight edge over Singapore in translating economic wealth to scientific wealth.

     

A bibliometric analysis of world volatile organic compounds research trends

This study explores a bibliometric approach to quantitatively assessing current research trends on volatile organic compounds, by using the related literature in the Science Citation Index (SCI) database from 1992 to 2007. The articles acquired from such literature were concentrated on the general analysis by scientific output, the research performances by countries, institutes, and collaborations, and the research trends by the frequency of author keywords, words in title, words in abstract, and keywords plus. Over the past years, there had been a notable growth trend in publication outputs, along with more participation and collaboration of countries and institutes. Research collaborative papers had shifted from the national inter-institutional to the international collaboration. Benzene, toluene, and formaldehyde were the three kinds of VOCs concerned mostly. Detection and removing, especially by adsorption and oxidation, of VOCs were to be the orientation of all VOCs research in the next few years.     

Applying bibliometric mapping in a high level science policy context

Bibliometric maps have the potential to become useful tools for science policy issues. The complexity of the structures, however, makes it often very difficult to interpret the results. In this study, we present a case study in which we use the bibliometric mapping results to address a high level science policy issue of research efficiency. By revealing the results in an alternative way, we increased the utility of bibliometric mapping within the science policy context. Moreover, by including additional information to the entities in the landscape, we provide useful input for the research potential.     

A bibliometric profile of top-scientists a case study in chemical engineering

We carefully selected a group of chemical engineering scientists internationally recognized as top-scientists in their field. A method has been developed to systematically compare bibliometric characteristics of these top-scientists with an average scientist in chemical engineering. This method also includes citation-analysis of books and proceedings. The results show a very clear bibliometric profile. First, top-scientists references are more numerous and, fourth, they concern more recent literature. Our fifth findings is that the journals used by top-scientists for their publications are representative for the field of chemical engineering as a whole. But they differ in specific aspects significantly from the average journal structure in chemical engineering: the published work of top-scientists is both general as well as more specialistic than the average work in chemical engineering.     

Citation patterns in little science and big science

The classification of citations by their context, previously formulated and used for other studies, is employed here to see if the citation patterns of big and little science are different or not. Theoretical physics articles in 1935 and 1955 are thus compared. No significant differences were found except in the number of references per article which increased significantly from 1935 to 1955, and again to 1968. It is found, however, that the German journal Zeitschrift für Physik has considerably higher percentages of conceptual, organic, and evolutionary citations, both in 1935 and in 1955, than The Physical Review. The interpretation of this difference remains unclear.

Meta-analysis in psychology: a bibliometric study

Meta-analysis refers to the statistical methods used in research synthesis for combining and integrating results from individual studies. The present study draws on the strengths of bibliometric methods in order to offer an overview of meta-analytic research activity in psychology, as well as to characterize its most important aspects and their evolution over time. A total of 2,874 articles published in scientific journals were identified and standard bibliometric indicators (e.g., number of articles, productivity by country, and national and international collaborations) and laws (e.g., Price’s and Lotka’s law) were applied to these data. The results suggest a clear upward trend not only in the number of articles published since the 1970s (with a peak of productivity in 2010), but also in both the number of authors by article ( $ \bar{x} = 2. 7 5 $ , SD = 1.53) and internationalization, especially since the 1990s. The interest in meta-analysis extends to many authors (n = 5,445), countries (n = 44) and scientific journals (n = 394), as well as to several areas of psychology that mostly fit a growing exponential model. In future studies it would be interesting to explore the citing behaviour and patterns in the meta-analysis literature.

Assessing multidisciplinary areas of science and technology: A synthetic bibliometric study of Dutch nuclear energy research

This paper presents a selection of results of a comprehensive quantitative, research literature-based study of Dutch energy research. The primary goal of this paper is to provide an overview of what bibliometric data from ISI and non-ISI databases may offer to describe the state of affairs in a scientific field. It illustrates the added value of combining bibliometric indicators of publication output, international visibility, international co-operation, and interdisciplinarity in a study of nuclear energy research in the 1980's when its budget decreased dramatically.     

A bibliometric study of differential item functioning

Summary This study presents a bibliometric analysis of scientific output in the area of Differential Item Functioning (DIF), the aim being to offer an overview of research activity in this field and characterise its most important aspects and their evolution over the last quarter of the 20th century, thus providing data regarding the basis on which this activity is being developed at the beginning of the 21st century. The analysis makes use of the Web of Science database, the search being restricted to articles published between 1975 and 2000 and which contain the terms differential item functioning, DIF or item bias. The various analyses focus on the presentation of publication frequencies and percentages, as well as on the application of Bradfords law of scattering and Lotkas law.     

Scientometrics of big science: a case study of research in the Sloan Digital Sky Survey

Large-scale scientific projects have become a major impetus of scientific advances. But few studies have specifically analyzed how those projects bolster scientific research. We address this question from a scientometrics perspective. By analyzing the bibliographic records of papers relevant to the Sloan Digital Sky Survey (SDSS), we found that the SDSS helped scientists from many countries further develop their own research; investigators initially formed large research groups to tackle key problems, while later papers involved fewer authors; and the number of research topics increased but the diversity of topics remains stable. Furthermore, the entropy analysis method has proven valuable in terms of analyzing patterns of research topics at a macroscopic level.     

A bibliometric study of bioinformatics research in South Africa

This paper reports on the practises of bioinformatics research in South Africa using bibliometric techniques. The search strategy was designed to cover the common concepts in biological data organisation, retrieval and analysis; the development and application of tools and methodologies in biological computation; and related subjects in genomics and structural bioinformatics. The South African literature in bioinformatics has grown by 66.5% between 2001 and 2006. However, its share of world production is not on par with comparator countries, Brazil, India and Australia.     

Improving the functionality of interactive bibliometric science maps

The use of a map as a metaphor of a scientific field is an established idea and using it as aninterface to bibliometric data seems to have great potential. Nevertheless, our own implementationof such an interface came up with some limits inhibiting the user to comprehend as to what hewas looking at. As a result, the map was not used to its fullest potential. The implementationdescribed in this paper as a high-level (conceptual) design, addresses the problems noted by users.It combines both top-down and bottom-up access to the bibliometric data, something we see asvital to mapping internal knowledge onto the external depiction and vice versa. And as such, itbecomes a more complete tool to explore the mapped scientific field and to find and retrieverelevant information.     

The decline of Swedish neuroscience: Decomposing a bibliometric national science indicator

Recent studies have reported on a steady decline of Sweden's relative citation impact in almost all science fields, above all in the life sciences. The authors attempt to shed light on the observed decline in Swedish neuroscience through a detailed citation analysis at different level of aggregations. Thus national citation data are decomposed to the institutional, departmental and individual level. Both, the decomposition of national science indicators and changing collaboration patterns in Swedish neuroscience reveal interesting details on the 'anatomy' of a decline. This revised version was published online in August 2006 with corrections to the Cover Date.     

International contribution to library and information science in Poland: A bibliometric analysis

This article reports findings from the study of the international contribution to the system of library and information science communication in Poland in the years 2003–2005. The sample consists of articles published both in selected journals and collective works. Two important dimensions determining the internationalization of local scholarly communication are considered: direct contribution (foreign authors’ articles and papers and their translations published in Poland) and indirect contribution (citedness of foreign authors’ documents in articles and papers published in Poland). Bibliographic data about the geographical distribution and affiliation of foreign authors are gathered and analyzed. Furthermore, the findings of citation analysis are presented to determine the percentage share of citations received by foreign documents as well as to find out what is the structure of such citations regarding the language and form, which thematic areas are most replete with such citations and which foreign journals are most cited in Poland.
