In this paper we explore the possibility of using bibliographic databases for tracking the geographic origin of surnames. Surnames are used as a proxy to determine the ethnic, genetic or geographic origin of individuals in many fields such as Genetics or Demography; however they could also be used for bibliometric purposes such as the analysis of s...

The study of science at the individual scholar level requires the disambiguation of author names. The creation of author's publication oeuvres involves matching the list of unique author names to names used in publication databases. Despite recent progress in the development of unique author identifiers, e.g., ORCID, VIVO, or DAI, author disambig-u...

The European Commission has requested a consortium consisting of TNO (NL), CWTS (NL) Technopolis (NL) and VDI (DE) to develop a methodology that enables assessing the scientific impact of the FET Research Initiatives. It also requested to trial the methodology on two FET-clusters: Bio-inspired ICT and Quantum Information Processing and Communicatio...

We define converging research as the emergence of an interdisciplinary research area from fields that did not show interdisciplinary connections before. This paper presents a process to search for converging research using journal subject categories as a proxy for fields and citations to measure interdisciplinary connections, as well as an applicat...

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 of bibliometric networks. We show that the VOS map...

Converging research is the emergence of new interdisciplinary research from fields which showed limited mutual interdisciplinary connections before. We describe three search strategies to identify converging research using data extracted from the WoS, including the social sciences and humanities. The field-to-field references (FFR) strategy uses ci...

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 labor-intensive. To overcome these disadvantages, we p...

This paper explores a methodology for delimitating scientific subfields by combining the use of (specialist) journal categories from Thomson Scientific’s Web of Science (WoS) and reference analysis. In a first step it selects all articles in journals included in a particular WoS journal category covering a subfield. These journals are labelled as a...

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 science policy issue of research efficiency. By reve...

The European Union, as well as national, regional, and even local government organizations across Europe, is promoting research and development collaborations as efficient and effective vehicles to turn ideas into new products, services, and solutions in order to improve competitiveness. One of the largest programs is the European Community Sixth F...

Field delineation is important in bibliometrics. Particularly when measuring scientific performance, the demarcation of the area, to which a science actor belongs, is of the greatest importance. This paper present a method based on searches on Boolean combinations of medical subject headings (MeSH-terms) in a combined Web of Science (WoS) - Medline...

The general aim of this paper is to show the results of a study in which we combined bibliometric mapping and citation network analysis to investigate the process of creation and transfer of knowledge through scientific publications. The novelty of this approach is the combination of both methods. In this case we analyzed the citations to a very in...

Summary We present a new bibliometric approach to identify research groups in a particular research field. With a combination of bibliometric mapping techniques and network analysis we identify and classify clusters of authors to represent research groups. In this paper we illustrate the application and potential of this approach and present two ty...

Summary 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 use of “qualitative maps”: an umbrella term f...

The evaluation of scientific endeavour is ultimately a learning process. Objective data containing bibliographic information can be visualized as bibliometric graphs. However, understanding the contents of this representation requires tools that support an intersubjective interpretation process. This paper presents an additional tool for bibliometr...

Maps of science provide visualizations of scientific knowledge domains by quantitatively grouping elements from scientific papers. In evaluative bibliometric studies these quantitative maps have proven a useful tool Representation schemes such as mental maps or cognitive maps provide a tool to structure qualitative reasoning about, for instance, st...

If we consider scientific output as measured by publication activity as a valid and useful representation of scientific knowledge, studies based on publications should be able to provide useful insights into the nature and distribution of public knowledge.

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 background of a number of studies conducted during t...

Bibliometric maps are scaled representations of clusters of papers and provide an overview of a scientific field as provided by those papers and the references between them. We have enhanced our interactive bibliometric explorer (iBEX) to visualise the distribution of phrases over such bibliometric maps. Assuming that generic (non-content-bearing)...

Bibliometric mapping of science within a science policy context required a different approach to visualization than for IR purposes. The identification of sub-domains within a field and their unchanged definition over time is crucial. A combination of this structure with actor characteristics provides possible answers to policy related questions. A...

We discuss the creation of ‘maps of science’ with help of advanced bibliometric methods. This ‘bibliometric cartography’ can be seen as a specific type of data mining, applied to large amounts of scientific publications. As an example we describe the mapping of the field mathematics & computer science.

The paper investigates the advantages of graphical mapping of national research publication and citation profiles from scientific fields in order to provide additional information with respect to research performance. By means of multi-dimensional scaling techniques national social science profiles from seventeen OECD countries and two periods, 198...

The use of a map as a metaphor of a scientific field is an established idea and using it as aninterface to bibliometric data seems to have great potential. Nevertheless, our own implementationof such an interface came up with some limits inhibiting the user to comprehend as to what hewas looking at. As a result, the map was not used to its fullest...

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 of hypertext and graphical interfaces. Because of t...

In this paper we present the explorations of combining the two main pillars of evaluative bibliometrics. These two pillars, performance analysis and science mapping, both have their strengths and imperfections. In this study we show how these imperfections are dealt with by an integrated analysis.

The general aim of the article is to demonstrate how the results both of a structural analysis, and of a research performance assessment of a research field, can be enriched by combining elements of both into one inte- grated analysis. In addition, a procedure is discussed to select and analyse candidate benchmark institutes to assess the position...

With the help of bibliometric mapping techniques, we have developed a methodology of “self-organized” structuring of scientific fields. This methodology is applied to the field of neural network research. We propose a field-definition based on the present situation. This is done by letting the data themselves generate a structure, and, with that, d...

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 interface enables the users of the maps to focus onto the...

In this paper the results of a bibliometric study of neural network research are presented. This evaluative study includes bibliometric mapping and actor analysis of main players in the field on a macro level (countries, in particular Germany), and, on a lower level, of the main players in Germany. We found that Germany is among the leading countri...

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) approach to develop a cartography of science and technolo...

The aim of this study is to investigate a specific aspect of the science and technology interface: inventor-author relations. The subject area is application of lasers in medicine. The empirical material consists of a set of 30 patents, representing the ‘technology side’ and 1057 publications authored by the inventors, representing the ‘science sid...

Several bibliometric methods of assessing the research performance of departments are examined: intranational comparison of departments, comparison with foreign departments of good standing, and comparison with a bibliometric world average. In the study, two Dutch experimental psychology departments were compared with one good US and one outstandin...

Methods are developed to compare the research performance of departments in two humanities disciplines, general linguistics and general literature. Departments from an Anglo-Saxon country were compared with several departments from European, non-Anglo-Saxon countries. A method was developed to reconstruct publication lists of departments, based on...

This paper addresses a bibliometric methodology to discover the structure of the scientific 'landscape' in or-der to gain detailed insight into the development of R&D fields, their interaction, and the transfer of knowl-edge between them. This methodology is appropriate to visualize the position of R&D activities in relation to interdisciplinary R&...

Monitoring and evaluation of research (R&D) activities, particularly in relation to socio-economic needs is high on the agenda of European policy-makers. At the same time, assessment of what is called ‘European Added Value’ is demanded. In fact, all these desiderata focus to a few crucial questions: How are specific R&D activities ‘embedded’ in the...
