The application of bibliometric analyses in the evaluation of social science research. Who benefits from it, and why it is still feasible

Summary The paper discusses an application of bibliometric techniques in the social sciences. While the interest of policy makers is growing, the topic is getting more and more attention from bibliometricians. However, many efforts are put into developing tools to measure scientific output and impact outside the world of the Social Sciences Citation Index, while the use of the SSCI for bibliometric applications is covered with obscurity and myths. This study attempts to clarify some of the topics mentioned against the application of the SSCI for evaluation purposes. The study will cover topics like the existing publication and citation culture within the social sciences, the effect of variable citation windows, and the (geographical) origin of citation flows.     

Systematic analysis of coverage and usage of conference proceedings in web of science

The role of conference proceedings for scientific communication varies among the different research fields. It is thus difficult to determine how to use them in bibliometric studies that cover all or at least a variety of the research fields without favouring or penalizing observation subjects that are specialized in fields that rely heavily on conference proceedings. Also, the coverage of conference proceedings in bibliometric databases is often unclear. Not only have there been reports of misclassification but also of insufficient coverage. In this study, the Web of Science is used to give an overview of coverage of conference proceedings as well as advantages and pitfalls of their usage in bibliometric analyses. In particular, the focus lies on different citation behaviour of and for conference proceedings and the implications for bibliometric indicators. This is complemented by an investigation of the development of coverage and publication behaviour in conference proceedings which is compared to those of journal publications. Finally, the importance but also drawbacks and opportunities of acknowledging conference proceedings publications for bibliometric studies are summarized.     

The publication and citation output of German Faculties of Economics and Social Sciences - a comparison of faculties and disciplines based upon SSCI data

Summary The purpose of this study is to quantify and compare the publication and citation output of the biggest faculties of economics and social sciences in Germany. Various publication and citation measures based upon Social Science Citation Index (SSCI) data are used to explore the comparative strengths and weaknesses of ten academic fields at the named faculties. To reflect the varying size of the fields and faculties, output measures as well as productivity measures are explicitly considered. From a bibliometric perspective empirical results demonstrate that various measures are necessary to adequately identify the comparative strengths and weaknesses of entire faculties and of selected disciplines within faculties.     

An item-by-item subject classification of papers published in journals covered by the SSCI database using reference analysis

A serious shortcoming of bibliometric studies based on theSocial Sciences Citation Index is the lack of a universally applicable subject classification scheme as individual papers are concerned. Moreover, the selective coverage of more than thousand scientific journals per annum proved to be an insuperable obstacle in the delimitation of social science subject areas. Subject classification of papers on the basis of assigning journals to subject categories (like those found in the various supplements of ISI databases) works well in case of fully covered and highly specialised journals in the social sciences, too, but fails for multidisciplinary and selectively covered journals. This study presents the results of an item-by-item subject classification approach, where assignment is based on the analysis of the subject categories of reference literature. This analysis extends the results of an earlier study by the authors on the possibility of delimiting subfields in the hard and life sciences based on reference analysis. The assignment proved also reliable for a considerable share of literature in the social sciences. Due to the peculiarities of the database this share is lower in the SSCI than that in the SCI. Although an iterated application of the procedure is expected to increase the number of classifiable publications, it is suggested that in the sociated sciences the method should be used in combination with other means of subject assignment.     

Korean journals in the Science Citation Index: What do they reveal about the intellectual structure of S&T in Korea?

During the last decade, we have witnessed a sustained growth of South Korea’s research output in terms of the world share of publications in the Science Citation Index database. However, Korea’s citation performance is not yet as competitive as publication performance. In this study, the authors examine the intellectual structure of Korean S&T field based on social network analysis of journal-journal citation data using the ten Korean SCI journals as seed journals. The results reveal that Korean SCI journals function more like publication places, neither research channels nor information sources among national scientists. Thus, these journals may provide Korean scholars with access to international scientific communities by facilitating the respective entry barriers. However, there are no citation relations based on their Korean background. Furthermore, we intend to draw some policy implications which may be helpful to increase Korea’s research potential.     

Difficulties and challenges of Chinese scientific journals: Statistical analysis of Chinese literatures using Chinese Science Bulletin as example

Using statistical method, the author analyzed the citation rate of articles published in Chinese Science Bulletin (CSB) between 1995 and 1999 in Science Citation Index Expanded (SCIE) databases. Results indicated that: 1. Majority of authors who published in CSB were Chinese; 2. The articles were basically cited by the authors themselves in the first year after publication; 3. The peak of total citation rate appeared in the third year after publication and the peak of non-self-citation rate was further delayed. There are relatively high self-citation rates of articles from CSB and most of these citations are from Chinese scientific journals. This indicates that our citation environment is limited to a closed circle. The author, therefore, proposed a strategy for changing the current conditions of Chinese scientific journals to raise their influence.

Full-text publications in peer-reviewed journals derived from presentations at three ISSI conferences

This study analyses the bibliometric characteristics of the presentations at the 5th, 8th and 10th Conferences of the International Society for Scientometrics and Informetrics, which were subsequently published in peer-reviewed journals covered by the Science Citation Index, Social Science Citation Index and LISA databases. 31.7% of all the papers presented at the three conferences were published. Scientometrics was the journal that published the highest proportions. A low rate of publication deprives researchers of potentially interesting results and points up the role of the ISSI Conference proceedings as a primary source of information.     

Cuban scientific articles in ISI Citation Indexes and CubaCiencias databases (1988-2003)

Summary This comparative study covers the period 1988-2003 of the Institute for Scientific Information Databases (ISI-DBs), CD-ROM edition: Science Citation Index (SCI), Social Sciences Citation Index (SSCI) and Arts & Humanities Citation Index (A&HCI) as international databases and from the CubaCiencias (CubaCiencias) as an internal database. The number of articles published in Cuban journals, ISI-DBs, the author associativeness trend, the most important institutions and other indicators are collected. However, it is observed that CubaCiencias and ISI-DBs are not perfectly suitable for a study of the productivity of Cuban authors. It is necessary to properly standardize the author fields. For bibliometric studies, Cuba needs a database not only for the published papers in Cuban journals, but also for all the papers published by Cuban authors.     

Use of citation per publication as an indicator to evaluate contingent valuation research

This is the first article using bibliometrics to study the field of contingent valuation research. The purpose of this study was to evaluate the contingent valuation research performance based on all the related articles in SCI and SSCI databases from 1991 to 2005. An indicator named citation per publication (CPP) was presented in this study to assess the impact of article output per year, different countries, institutes, and authors from the worldwide. Publication per institute (PPI) in a country was used to be an indicator to compare institute’s research performance by country. Citation analysis was made to select the most frequently cited articles since publication to 2005 of each year. A citation model was applied to describe the relationship between the cumulative number of citations and article life. The results indicate that with the increase article output per year, the CPP decreased slightly since 1997. The USA produced 55% of all pertinent articles. Institutes from the UK had a higher PPI. The most prolific institutes and authors, and the most frequently cited articles per year were all listed. In addition, a citation model was successfully applied to evaluate performance of each year, and the most frequently cited articles of each year were also compared by the model.     

Use of citation per publication as an indicator to evaluate pentachlorophenol research

The objective of the study was to perform a bibliometric analysis of all pentachlorophenolrelated publications in the Science Citation Index (SCI). Analyzed parameters included document type, language of publication, page count, publication output, authorship, keywords plus, publication pattern, citation and country of publication. The US produced 29% of the total single country publications where the seven major industrial countries accounted for the majority of the total production (66%). An indicator citation per publication was successfully applied in this study to evaluate the impact of number of authors, countries, and journals. The mean value of citation per publication of collaborative papers was higher than that of single country publications. In addition analysis of keywords plus in different period was applied to indicate a research trend.     

Bibliometric monitoring of research performance in the Social Sciences and the Humanities: A Review

Summary This paper addresses research performance monitoring of the social sciences and the humanities using citation analysis. Main differences in publication and citation behavior between the (basic) sciences and the social sciences and humanities are outlined. Limitations of the (S)SCI and A&HCI for monitoring research performance are considered. For research performance monitoring in many social sciences and humanities, the methods used in science need to be extended. A broader range of both publications (including non-ISI journals and monographs) and citation indicators (including non-ISI reference citation values) is needed. Three options for bibliometric monitoring are discussed.     

International Co-operation in Science and in Social Sciences as Reflected in Multinational Papers Indexed in SCI and SSCI

The paper presents a comparative analysis of publications, co-authored by Polish and foreign researchers, selected from seven annual files ofScience Citation Index and Social Sciences Citation Index (CD-ROM Editions 1992–1998). Information obtained from SCI and SSCI were elaborated, completed, coded and entered in two “international files” designed for analytical purposes. It was found that the number of internationally co-authored papers was many times higher (18982 records) in science than in social sciences (342 records). The share of these “international papers” in the “Polish files” increased in the time under review, but for those derived from SCI was also higher (39.1 – 46.0%) than in case of SSCI (22.4 – 37.0%). Results of the analysis include countries of foreign partners and affiliation of domestic co-authors, as well as, subject structure of both international files. Observed differences in the scale of international co-operation in science and in social sciences are being the matter under discussion.

Applying research collaboration as a new way of measuring research performance in Korean universities

The purpose of this study is to explore the possibility of applying research collaboration as a new way of measuring research performance in Korean universities. In this study, we examine whether the activeness of research collaboration between university–government–industry can also enact as a way to measure the research performance aside from the typical indicators such as number of published articles or citations resulted from universities. Also this study focuses to analyze whether such performance differs according to universities’ characteristics and disciplines. For the analysis of the study, we gathered publication and citation data (2000–2009) of 46 Korean universities that are actively involved in research and analyzed their science citation index-expanded and the social sciences citation index (SSCI) data. Notable findings include (1) Several low ranked universities have shown rapid improvement with their research performance despite the rigid hierarchical characteristic of Korean higher education system, (2) Although universities in Korea are involved in various kinds of collaboration methods, it was evident that such dynamic is not necessarily reflected in existing hierarchy structure, (3) Academic relations with education oriented universities and research oriented universities have different dynamics and patterns in research collaboration, (4) In terms of the collaborative publication rate, private universities collaborate more actively amongst university sector whereas public universities collaborate more with government and industry. (5) Due to the nature of the social science subject itself, it was found that the research in SSCI is inevitably more based on the researcher’s independence, hence more international collaboration was found amongst researchers in natural science and engineering subjects.     

Patents cited in the scientific literature: An exploratory study of 'reverse' citation relations

This paper reports on a new approach to study the linkage between science and technology. Unlike most contributions to this area we do not trace citations of scientific literature in patents but explore citations of patents in scientific literature. Our analysis is based on papers recorded in the 1996-2000 annual volumes of the CD-Edition of Science Citation Index (SCI) of the Institute for Scientific Information (ISI) and patent data provided by the US Patent and Trademark Office. Almost 30,000 US patents were cited by scientific research papers. We analysed the citation links by scientific fields and technological sectors. Chemistry-related subfields tended to cite patents more than other scientific area. Among technological sectors, chemical clearly dominates followed by drugs and medical patents as the most frequently cited categories. Further analyses included a country-ranking based on inventor-addresses of the cited patents, a more detailed inspection of the ten most cited patents, and an analysis of class-field transfers. The paper concludes with the suggestions for future research. One of them is to compare our 'reverse' citation data with 'regular' patent citation data within the same classification system to see whether citations occur, irrespectively of their directionality, in the same fields of science and technology. Another question is as to how one should interpret reverse citation linkages.     

Citation regression analysis of computer science publications in different ranking categories and subfields

A number of bibliometric studies point out that the role of conference publications in computer science differs from that in other traditional fields. Thus, it is interesting to identify the relative status of journal and conference publications in different subfields of computer science based on the citation rates categorised by the China Computer Federation (CCF) classifications and venue types. In this research, we construct a dataset containing over 100,000 papers recommended by the CCF catalogue and their citation information. We also investigate some other factors that often influence a paper’s citation rate. An experimental study shows that the relative status of journals and conferences varies greatly in different subfields of computer science, and the impact of different publication levels varies according to the citation rate. We also verify that the classification of a publication, number of authors, maximum h-index of all authors of a paper, and average number of papers published by a publication have different effects on the citation rate, although the citation rate may have a different degree of correlation with these factors.     

South African research in selected scientific areas: Status 1981–2000

The paper is a bibliometric study of the publication and citation patterns and impact of South African research 1981–2000 in five selected research fields: Animal & Plant sciences; Chemistry; Biochemistry; Microbiology & molecular biology, including genetics; and Physics, excluding Space science. Data are collected from Science Citation Index via the ISI product National Science Indicators. With the exception of Microbiology & molecular biology and Physics the results demonstrate a decrease of SA publications from 1986–1990. The SA world share declines for all five fields. First from the period 1994–1998 the Animal & plant sciences and Microbiology & molecular biology turn the decline into an increase. Absolute citation impact is increasing for all the fields from 1989–1993, except for Chemistry. One reason for the decline is a lower publication output. General & internal medicine, as an supplementary volume-heavy field observed, declines in citations until that same period from which it becomes stable, also in impact, but with a marked decrease in cited paper proportion. In citation world shares the five fields combined show positive signs also since 1989–1993, after which period the international eco-political embargo of SA was lifted. However, Biochemistry and Chemistry continue to decline during the 1990s. Citation impact relative to the world shows a similar pattern, but stagnation appears towards the end of the 1990s in all the observed fields combined. The trends are quite similar to those of Mexico and New Zealand. It is thus highly uncertain if a general citation embargo of SA occurred; yet, in some fields like the Animal & plant sciences, Veterinary science, Chemistry, and General & internal medicine there are signs that a mild citation embargo might have occurred. However, the economic embargo, combined with a significant brain drain, may have had an effect on the publication productivity, after it was lifted. For all indicators Chemistry is undergoing a marked decline during the last decade. This is in line with the negative trends for General & internal medicine, whereas some other medical specialities, biology, economics and other social sciences, the engineering fields and materials sciences keep stable or increase their production. SA is in line with the Mexican development but below that of New Zealand, seemingly losing ground to the developed countries.

Research output in pheromone biology: a case study of India

Analyses the growth and development of pheromone biology research productivity in India in terms of publication output as reflected in Science Citation Index (SCI) for the period 1978–2008. It includes 330 publications from India, including 285 articles, 22 notes, 18 reviews, 4 letters and 1 conference paper, from 200 institutions. About 9.4 % of publications is contributed by Indian Institute of Technology, Kanpur followed by Bhabha Atomic Research Centre, Bombay (7.27 %). All the papers published by Indian researchers have appeared in journals with impact factors between 0.20 and 4.14. About 24.24 % of authors contributed single articles. The growth rate of publications varied from 0.30 to 9.09 % per year. The annual growth rate was highest in the year 2006 at 9.09 %. The study reveals that the output of pheromone biology research in India has gradually increased over the years.
