Az eponímák, a személyekről elnevezett tudományos fogalmak, nagy hagyományokkal rendelkeznek az orvostudományban is. Létrejöttük, használatuk a tudománymetria számára is érdekes tanulságokkal szolgál. Egy orvostudományi mintán a szerző megmutatja, hogy bár az eponímák alapjául szolgáló publikációkra való hivatkozások idővel kikopnak a szakirodalomból, e cikkek idézettsége még mindig sokszorosa a velük egyidős más publikációk idézettségének.

Summary
In order to easily see the citation patterns of a journal or subject area it is very useful to use a graphical diagram to visualize all the connections between journals. Using data derived from the Journal Citation Reports, this study investigates the visualization of citation patterns for three Canadian journals in three different subject areas: library and information science, psychology and mathematics.
Abstract
The database host STN International allows for extensive citation analysis in the SCISEARCH database (Science Citation Index Expanded) and in the CAplus database (Chemical Abstracts). Along with its powerful browsing, searching and analyzing facilities, STN International also features scripts. In this paper we examine the usefulness of the script language in the automation of citation analysis in SCISEARCH and CAplus.
Abstract
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.
Abstract
The important role of the Institute for Scientific Information'sScience Citation Index (SCI) as an international retrieval and evaluation tool is briefly discussed. The role ofChinese Science Citation Database (CSCD), the counterpart of SCI in China, in improving the application of citation retrieval method in China, is summarized. The construction process and status quo of CSCD are explained.
The discussion about how to treat author self-citations driven by policy application and quality measurement intensified in the last years. The definition introduced by Snyder and Bonzi has - in lack of any reasonable alternative - been used in bibliometric practice for science policy purposes. This method, however, does not take into account the weight of self-citing authors among co-authors of both the cited and citing papers. The objective of the present paper is to quantify the weight of self-citations with respect to co-authorship. The analysis is conducted at two levels: at the macro level, namely, for fifteen subject fields and the most active forty countries, and at the meso level, for a set of selected research institutions.
Abstract
The objective of this research is to develop a new patent bibliometric performance measure by using modified citation rate analyses with dynamic backward citation windows. Cited half-life employed in bibliometrics was adopted in order to establish a model of annual patent backward citation windows. Based on the dynamic behavior of backward citation windows, the annual backward patent citation rates for each technology domain can be calculated to measure its bibliometric performance. It was found that the dynamic backward citation window represents more accurately the citation cycle time which is a key factor on technology assessment. Because different technology domain may have disparate attributes, a normalized backward citation rate was developed to measure the corresponding rank for each domain respect to the entire industry. Three technology domains were then chosen for demonstrative case studies which represent semiconductor, LCD, and drug industries.
Abstract
This project compares various bibliometric measures and scientists' own judgments. Publication and cittion data are compiled for two cohorts of chemists awarded Sloan Fellowships. Citation patterns differ substantially between most cited papers and those these authors identify as their best. Theoretical, empirical, and methodological papers are contrasted as well. In addition, temporal citation patterns show that recognition spreads beyond the research area of a particular paper to yield cross-disciplinary citation surprisingly rapidly. Results suggest the utility of studying citation patterns among the Institute for Scientific Information Subject Categories, but also caution against equating publication and citation counts with scientific progress.
Abstract
In recent papers, the authors have studied basic regularities of author self-citations. The regularities are related to the ageing, to the relation between self-citations and foreign citations and to the interdependence of self-citations with other bibliometric indicators. The effect of multi-authorship on citation impact has been shown in other bibliometric studies, for instance, by Persson et al. (2004). The question arises whether those regularities imply any relation between number of co-authors and the extent of author self-citations. The results of the present paper confirm the common notion of such effects only in part. The authors show that at the macro level multi-authorship does not result in any exaggerate extent of self-citations.
