    Notes: Abstract This paper reports on a quantitative analytical methodology which deals with perceptions of scientific experts regarding the intellectual shape and contents (‘cognitive structure’) of their scientific domain. This study examines the method's utility for studying expert views in general, and, more specifically, its strengths and weaknesses as a tool for improving validation studies of bibliometric maps involving subject experts. The main premise is that expert views are based on their internal knowledge structures (‘mental schemes’) of which relevant features can be captured in quantitative data. This approach allows a rigorous and systematic way of studying mental schemes across subject experts. Spatial representations of their data (‘mental maps’) provide insight in properties underlying those knowledge structures. Data from different experts are reconciled to construct a ‘common’ mental map which displays a group view. This study includes a test to establish the validity of individual mental maps and common mental maps. The methodology is applied to the views of 14 researchers in the field of neural network research and related areas. Key-findings are: (i) mental maps can provide valid representations of expert mental schemes, (ii) experts sharing the same subject field are more likely to share views, (iii) expert judgements of bibliometric maps are affected by the structure of their own mental schemes, as well as (iv) by their views regarding the utility of those maps, and (v) common mental maps and a bibliometric co-word map based on the same set of items differ significantly, showing a resemblance on main features only.

    Notes: Abstract The science and engineering base is a key source of knowledge for the development and use of Information and Communication Technologies (ICTs). In order to be able to effectively describe and monitor world-wide scientific activity related to ICTs, it is important to be able to provide reliable macro-level statistics of this knowledge base. International bibliographic databases and related bibliometric indicators together provide an analytical framework and appropriate measures to cover both the ‘supply side’—research capabilities and outputs—and ‘demand side’—collaboration, diffusion and citation impact—related to the ICT research. This paper presents results of such a bibliometric study describing macro-level features of this ICT knowledge base. The data were retrieved from a specially developedCWTS ICT Database which provides a broad-scope world-wide coverage of ICT-relevant research papers published in high-quality international scientific and technical journals. The cross-country comparison focuses on the level of scientific output and co-operation patterns of the most actively publishing nations with a focus on the three Triad zones—the European Union, the USA and Japan.

    Notes: Abstract A growing science policy interest in international scientific collaboration has brought about a multitude of studies which attempt to measure the extent of international scientific collaboration between countries and to explore intercountry collaborative networks. This paper attempts to clarify the methodology that is being used or can be used for this purpose and discusses the adequacy of the methods. The paper concludes that, in an analysis of collaborative links, it is essential to use both absolute and relative measures. The latter normalize differences in country size. Each yields a different type of information. Absolute measures yield an answer to questions such as which countries are central in the international network of science, whether collaborative links reveal a centre — periphery relationship, and which countries are the most important collaborative partners of another country. Relative measures provide answers to questions of the intensity of collaborative links.

    Notes: Abstract The research output of the Danish Technical University (DTUa) has been studied as an aspect of the organization's research policy and visibility in its international context. Papers published in the three-year period (1992–94) were grouped according to 20 clusters of research areas. Using citation analysis techniques, the dynamics of citation frequencies, and a number of other features of the research system, like self-citation, research collaborations, relative impact on the international literature, etc., could be studied. The methods can be used to analyze institutional and national research efforts and to monitor effects of changing policies.

    Notes: Abstract This article presents results of a study on the applicability of journal mapping of knowledge domains beyond the databases produced by the Institute for Scientific Information (ISI). The utility and validity of this generalisation is discussed with an emphasis on its added value in comparison to ‘traditional’ ISI-based journal maps, i.e. those restricted to (predominantly English-language) ISI-covered journals, and journal-to-journal citation data retrieved from ISI'sJournal Citation Reports. The mapping methodology was applied to Manufacturing technology and management — a multidisciplinary domain situated on the interface of science and technology. TheInternational Journal of Production Economics was singled out as a special case for the validation study of the maps. Results of this study, involving several subject experts, indicate that a journal content-based map was not only far superior to the journal citation map, but also outperformed the map derived from the combination of both types of data. The selection of periodicals from other databases such as COMPENDEX produced a substantial number of additional titles of which only half were also covered by ISI.

    Notes: Abstract This paper presents a selection of results of a comprehensive quantitative, research literature-based study of Dutch energy research. The primary goal of this paper is to provide an overview of what bibliometric data from ISI and non-ISI databases may offer to describe the state of affairs in a scientific field. It illustrates the added value of combining bibliometric indicators of publication output, international visibility, international co-operation, and interdisciplinarity in a study of nuclear energy research in the 1980's when its budget decreased dramatically.

    Notes: Abstract In this paper we discuss the limits and potentials of bibliometric mapping based on a specific co-word analysis. The subject area is neural network research. Our approach is a ‘simulation’ of expert assessment by offering the reader a narrative of the field which can be used as background information when ‘reading’ the bibliometric maps. The central issue in the applicability of bibliometric maps is whether these maps may supply ‘additional intelligence’ to users. In other words, whether such a bibliometric tool has an epistemological value, in the sense that it ecriches existing knowledge by supplying ‘unexpected’ relations between specific ‘pieces’ of knowledge (‘synthetic value’) or by supplying ‘unexpected’ problems (‘creative value’). We argue that sophisticated bibliometric mapping techniques are indeed valuable for open new avenues to study science as a self-organizing system in the form of a ‘neural network like’ structure of which the bibliometric map is a first-order aproximation. In that sense, this paper deals with the ‘neural net of neural network research’ as our bibliometric techniques in fact mimic a connectionistic approach.

    Notes: Abstract The LEXIMAPPE method and Multidimensional Scaling (MDS) are discussed as methods to visualize (‘map’) characteristics of structures of word-occurrence (‘co-word’) relations. Utilization of MDS is proposed as an alternative mapping method able to circumvent problematic features of LEXIMAPPE maps of the total co-word structure. A comparison of both methods on the same ‘real-life’ co-word matrix demonstrates topological advantages of an extended MDS-mapping.

    Notes: Abstract International scientific co-operation (ISC) and awareness are topics of increasing interest for both scientists and science policy makers. In this paper, we adopt primarily the science policy point of view. After a concise overview of the literature we summarize the main results of the research we conducted. The main outcome with respect to ISC is that it increases. However, large differences exist between countries and between scientific disciplines. ISC and awareness constitute a complex phenomenon, affected by several factors, science-internal, as well as external. In the paper several techniques are described, amongst which those that can visualize ISC relations through analytical maps. An important aspect of our research methodology is the combination of various quantitative, bibliometric analyses and qualitative research on the structure of science and the relations between science and society. Finally, we sketch perspectives for future research.
