A unified approach to mapping and clustering of bibliometric networks
JOURNAL OF INFORMETRICS; 2010: 629 - 635
In the analysis of bibliometric networks, researchers often use mapping and clustering techniques in a combined fashion. Typically, however, mapping and clustering techniques that are used together rely on very different ideas and assumptions. We propose a unified approach to mapping and clustering ...
Advanced mapping of science and technology
Scientometrics; 1998: 61 - 67
In the paper we will present the adjustments we implemented on the mapping procedure. We consider them as important improvements to make the maps more user-friendly. The improvements concern the implementation of graphical user interfaces, and the addition of 'map-external' information. This ...
Applying bibliometric mapping in a high level science policy context
SCIENTOMETRICS; 2009: 261 - 275
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 ...
Assessment of Flemish R&D in the field of information technology - A bibliometric evaluation based on publication and patent data, combined with OECD research input statistics
RESEARCH POLICY; 1998: 285 - 300
This paper outlines a method to evaluate a geographic region's performance in a research field. Using bibliometric indicators, an overview is given of Flemish R&D potential in information technology (IT). Flemish IT activity is presented within the context of recent international developments in ...
ASSESSMENT OF THE INTERNATIONAL STANDING OF UNIVERSITY DEPARTMENTS RESEARCH - A COMPARISON OF BIBLIOMETRIC METHODS
SCIENTOMETRICS; 1992: 393 - 404
Automatic term identification for bibliometric mapping
SCIENTOMETRICS; 2010: 581 - 596
A term map is a map that visualizes the structure of a scientific field by showing the relations between important terms in the field. The terms shown in a term map are usually selected manually with the help of domain experts. Manual term selection has the disadvantages of being subjective and ...
Bibliometric assessment of research performance in Flanders: policy background and implications
R & D MANAGEMENT; 1999: 133 - 141
We illustrate the use of bibliometric tools in the evaluation of scientific research conducted at Flemish universities and publicly funded research organisations, and in the assessment of scientific-technological performance in Flanders in the field of information technology. We sketch the policy ...
Bibliometric cartography of scientific and technological developments of an research-and-development field - the case of optomechatronics
Scientometrics; 1994: 157 - 173
This paper presents the results of an exploration of bibliometric mapping as an analytic tool to study the important aspects of the relation between science and technology, in particular the 'science base' of technology. We discuss a bibliometric (in particular a publication- and patent-based) ...
Bibliometric mapping of science in a science policy context
SCIENTOMETRICS; 2001: 83 - 98
Despite the promising introduction of bibliometric maps of science in a science policy context in the nineteen seventies, they have not been very successful yet. It seems, however, that only now they are becoming acknowledged as a useful tool. This is mainly due to the developments and integration ...
Combining concept maps and bibliometric maps: First explorations
SCIENTOMETRICS; 2006: 377 - 387
Bibliometric maps of science are a well-established research subject. But their adoption as a science policy support tool is lacking. We think this is because the user does not immediately comprehend a map and (as a result) is not enticed into using it. To help this comprehension, we propose the ...
