The development of scientometric indicators and methods for evaluative purposes, requires a multitude of assumptions, conventions, limitations, and caveats. Given this, we cannot permit ambiguities in the key concepts forming the basis of scientometric science itself, or research assessment exercises would rest on quicksand. This conceptual work attempts to spell out some principles leading to a clear definition of “impact” of research, and above all, of the appropriate scientometric indicator to measure it. The aim is to stimulate a discussion aimed at a definitive convergence on the meaning and measurement of a fundamental concept of the scientometric science. 相似文献

In tandem with the rapid globalisation of science, spatial scientometrics has become an important research sub-field in scientometric studies. Recently, numerous spatial scientometric contributions have focused on the examination of cities’ scientific output by using various scientometric indicators. In this paper, I analyse cities’ scientific output worldwide in terms of the number of journal articles indexed by the Scopus database, in the period from 1986 to 2015. Furthermore, I examine which countries are the most important collaborators of cities. Finally, I identify the most productive disciplines in each city. I use GPS Visualizer to illustrate the scientometric data of nearly 2200 cities on maps. Results show that cities with the highest scientific output are mostly located in developed countries and China. Between 1986 and 2015, the greatest number of scientific articles were created in Beijing. The international hegemony of the United States in science has been described by many studies, and is also reinforced by the fact that the United States is the most important collaborator to more than 75% of all cities. Medicine is the most productive discipline in two-thirds of cities. Furthermore, cities having the highest scientific output in specific disciplines show well-defined geographical patterns. 相似文献

Spatial scientometrics: Towards a cumulative research program 总被引：1，自引：0，他引：1
We propose a research program to analyse spatial aspects of the science system. First, we provide a review of scientometric studies that already explicitly take the spatial dimension into account. The review includes studies on (i) the spatial distribution of research and citations, (ii) the existence of spatial biases in collaboration, citations and mobility, and (iii) the citation impact of national versus international collaborations. Then, we address a number of methodological issues in dealing with space in scientometrics. Finally, to integrate spatial and non-spatial approaches, we propose an analytical framework based on the concept of proximity. A proximity approach allows for combining hypotheses from different theoretical perspectives into a single framework. 相似文献

This paper presents a review of publications that explore the role of editorial boards for scholarly journals. Such studies are rather limited as the role of editorial boards of scientific periodicals has not yet been fully gauged by information experts as a subject of scientometric research. However, the study of the publication activities, as well as the geographic, linguistic, and gender distribution of editorial-board members offers a new perspective on several issues of relevance to scientometrics. Such issues include the assessment of research performance at the country, organizational, or research-group level; research and publication ethics; journal quality; and internationalization of a scientific discipline. 相似文献

This article supports the idea of introducing an indicator that would account for articles that containing findings of experimental research in the process of the development of scientometric systems. Articles of this type appear to be the only “imprint” of research, while the rising number of publications falls short of reflecting the actual level of scientific achievements. 相似文献

Proper field delineation plays an important role in scientometric studies, although it is a tough task. Based on an emerging and interdisciplinary field nanoscience and nanotechnology– this paper highlights the problem of field delineation. First we review the related literature. Then, three different approaches to delineate a field of knowledge were applied at three different levels of aggregation: subject category, publication level, and journal level. Expert opinion interviews served to assess the data, and precision and recall of each approach were calculated for comparison. Our findings confirm that field delineation is a complicated issue at both the quantitative and the qualitative level, even when experts validate results. 相似文献

Genre is considered to be an important element in scholarly communication and in the practice of scientific disciplines. However, scientometric studies have typically focused on a single genre, the journal article. The goal of this study is to understand the role that handbooks play in knowledge creation and diffusion and their relationship with the genre of journal articles, particularly in highly interdisciplinary and emergent social science and humanities disciplines. To shed light on these questions we focused on handbooks and journal articles published over the last four decades belonging to the research area of science and technology studies (STS), broadly defined. To get a detailed picture we used the full-text of five handbooks (500,000 words) and a well-defined set of 11,700 STS articles. We confirmed the methodological split of STS into qualitative and quantitative (scientometric) approaches. Even when the two traditions explore similar topics (e.g., science and gender) they approach them from different starting points. The change in cognitive foci in both handbooks and articles partially reflects the changing trends in STS research, often driven by technology. Using text similarity measures we found that, in the case of STS, handbooks play no special role in either focusing the research efforts or marking their decline. In general, they do not represent the summaries of research directions that have emerged since the previous edition of the handbook. 相似文献

Variables subject to an order restriction, for instance Y ≤ X, have a bivariate distribution over a non-rectangular joint domain that entails a non-null and potentially large structural relation even if the variables show no association (in the sense that particular ranges of values of X do not co-occur with particular ranges of values of Y). Order restrictions affect a number of scientometric indices (including the h index and its variants) that are routinely subjected to correlational analyses to assess whether they provide redundant information, but these correlations are contaminated by the structural relation. This paper proposes an alternative definition of association between variables subject to an order restriction that eliminates their structural relation and reverts to the conventional definition when applied to variables that are not subject to order restrictions. This alternative definition is illustrated in a number of theoretical cases and it is also applied to empirical data involving scientometric indices subject to an order restriction. A test statistic is also derived which allows testing for the significance of an association between variables subject to an order restriction. 相似文献

This paper suggests a new scientometric index that estimates knowledge diffusion and has two constituents: the first one is equivalent to a usual citation index, i.e., it describes the visible diffusion of scientific knowledge; the second one reflects the implicit diffusion of scientific knowledge and is expressed through the number of implicit citations. The practical value of the suggested index is that it permits implicit initiators of the scientific mainstream to be easily identified. The distinctive feature of such scientists is the large value of the suggested citation index and the low value of the usual citation index. 相似文献

We present a novel algorithm to rank smaller academic entities such as university departments or research groups within a research discipline. The Weighted Top Candidate (WTC) algorithm is a generalisation of an expert identification method. The axiomatic characterisation of WTC shows why it is especially suitable for scientometric purposes. The key axiom is stability – the selected institutions support each other's membership. The WTC algorithm, upon receiving an institution citation matrix, produces a list of institutions that can be deemed experts of the field. With a parameter we can adjust how exclusive our list should be. By completely relaxing the parameter, we obtain the largest stable set – academic entities that can qualify as experts under the mildest conditions. With a strict setup, we obtain a short list of the absolute elite. We demonstrate the algorithm on a citation database compiled from game theoretic literature published between 2008–2017. By plotting the size of the stable sets with respect to exclusiveness, we can obtain an overview of the competitiveness of the field. The diagram hints at how difficult it is for an institution to improve its position. 相似文献
