- We investigate the distribution of domain names and the distribution of links between web sites. It is shown that the Lotka function provides an adequate description. The percentage of self-sitations is also determined.Published in 1997.
- Social network analysis (SNA) is not a formal theory in sociology but rather a strategy for investigating social structures. As it is an idea that can be applied in many fields, we study, in particular, its influence in the information sciences. Information scientists study publication, citation and co-citation networks, collaboration structures and other forms of social interaction networks. Moreover, ...
- Published in 1986.
- Summary The h-index (or Hirsch-index) was defined by Hirsch in 2005 as the number h such that, for a general group of papers, h papers received at least h citations while the other papers received no more than h citations. This definition is extended here to the general framework of Information Production Processes (IPPs), using a source-item terminology. ...
- Journal: Journal of The American Society for Information Science and Technology - JASIS , vol. 51, no. 2, pp. 145-157, 2000
- THISESSAY PROVIDES AN OVERVIEW ofjournal evaluation indicators. It highlights the strengths and weaknesses of different indicators, together with their range of applicability. The definition of a "quality journal," dif- ferent notions of impact factors, the meaning of ranking journals, and possible biases in citation databases are also discussed. Attention is given to using the journal impact in evaluation studies. The ...
- An h-type index is proposed which depends on the obtained citations of articles belonging to the h-core. This weighted h-index, denoted as hw, is presented in a continuous setting and in a discrete one. It is shown that in a continuous setting the new index enjoys many good properties. In the discrete setting some small deviations from ...
- We show that usually the influence on the Hirsch index of missing highly cited articles is much smaller than the number of missing articles. This statement is shown by a combinatorial argument. We further show, by using a continuous power law model, that the influence of missing articles is largest when the total number of publications is small, and non-...
- It is shown that Data Envelopment Analysis (DEA) ca be used to construct relative scientific and technological indicators. The method is explained and illustrated using countries as objects of study; GDP, active population and R&D expenditure as inputs, and publications and patents as outputs. Using these parameters the efficiency of countries is assessed.
- The influence of publication delays on the observed aging distribution of scientific literature(Citations: 28)
Journal: Journal of The American Society for Information Science and Technology - JASIS , vol. 51, no. 2, pp. 158-165, 2000 - We give an overview of the main data of a publication-citation matrix. We show how impact factors are defined, and, in particular, point out the difference between the synchronous and the diachronous impact factor. The advantages and disadvantages of using both as tools in research evaluation are discussed.
- Journal: Journal of The American Society for Information Science and Technology - JASIS , vol. 56, no. 1, pp. 58-62, 2005
- Summary In a recent article Sombatsompop et al. (2004) proposed a new way of calculating a synchronous journal impact factor. Their proposal seems quite interesting and will be discussed in this note. Their index will be referred as the Median Impact Factor (MIF). I explain every step in detail so that readers with little mathematical background can understand and apply ...
- Published in 1990.
- In this note we clarify some notions concerning citations, publications, and their quotients: impact and indifference (a measure of invisibility, introduced in this article). In particular, we show that the slope of the regression line of the impact as a function of the number of publications is positive if and only if the global impact, i.e. the impact of ...

- Alternative area-perimeter ratios for measurement of 2D shape compactness of habitats(Citations: 24)Area-perimeter ratios are often used to quantify 2D shape compactness. Shape compactness is of main importance to evaluate the effect of external disturbance on natural habitats. Reference values (Amin(p), Amax(p), Pmin(a), Pmax(a)) for area (A) and perimeter (P) are defined and proven. The calculation of these reference values is based on the characteristics of the ...

- In this article we study directed, acyclic graphs. We introduce the head and tail order relations and study some of their properties. Recalling the notions of generalized bibliographic coupling and generalized co-citation, and introducing a new property, called the l - property, we come to a characterization of lattices. As document citation networks are concrete realizations of directed acyclic graphs ...
- In this study we continue the application of Data Envelopment Analysis (DEA) to assess the efficiency and effectiveness of the R&D effort of European countries. We use GDP, active population and R&D expenditure as inputs, and publications and patents as outputs. Being effective means that, in order to obtain a maximum efficiency score countries are forced ...
- The purpose of this article is to find a model for the first-citation or response distribution. Starting from plausible assumptions, we derive differential equations, whose solutions yield the requested functions. In fact, we propose two different double exponential distributions as candidates to describe the first-citation process. We found that some real data are best fitted by the first ...
- Summary A chronically weak area in research papers, reports, and reviews is the complete identification of background documents that formed the building blocks for these papers. A method for systematically determining these seminal references is presented. Citation-Assisted Background (CAB) is based on the assumption that seminal documents tend to be highly cited. CAB is being applied presently to three ...
- Temporal differences in self-citing and self-cited rates of journals are studied. It is concluded that the citation curve of a journal is composed of two curves with different characteristics: a self-citation (or self-cited) curve and a curve representing external citations.
- Journal: Journal of The American Society for Information Science and Technology - JASIS , vol. 52, no. 8, pp. 610-614, 2001
- The definitions of the rational and real-valued variants of the h-index and g-index are reviewed. It is shown how they can be obtained both graphically and by calculation. Formulae are derived expressing the exact relations between the h-variants and between the g-variants. Subsequently these relations are examined. In a citation context the real h-index ...
- Problems with the notion of evenness, such as ambiguity, proliferation of indices, choice of indices, etc. can be overcome by a more fundamental, mathematical approach. We show that the Lorenz curve is an adequate representation of evenness. The corresponding Lorenz order induces a partial order in the set of equivalent abundance vectors. Also diversity can adequately be studied through a ...Journal: Environmental and Ecological Statistics - ENVIRON ECOL STAT , vol. 6, no. 2, pp. 211-223, 1999
- A review is given of recent developments related to the h-index and h-type indices. Advantages and disadvantages of the h-index are listed. Properties of generalizations of the h-index are shown. Woeginger's axiomatic approach to the study of impact indicators is highlighted as the most exciting development in recent months.
- The relation between the Hirsch index and Egghe's g-index is determined for some simple models such as the uniform model, the point model, the linear model and Zipf's model.
