Simultaneous mapping of interactions between S&T knowledge bases: The case of space communications
This paper examines the knowledge structure of the field of space communications using bibliometric mapping techniques based on textual analysis. A new approach with the aiming of visualizing simultaneously the configuration of its scientific and technological knowledge bases is presented. The bibliometric map revealed weak cognitive interactions between science and technology at the worldwide level although it brings out the systemic nature of the process of knowledge production at either side. We extended the mapping approach to the research activities of the Triad countries in order to characterize their specialization profiles and cognitive links on both sides in comparison with the structure of the field at the worldwide level. Results showed different patterns in the way the Triad countries organized their scientific and technological research activities within the field."bibliometric mapping" "S&T interactions" "space communications" "knowledge bases" "knowledge flows"
Bibliometric mapping as a science policy and research management tool
Bibliometric maps of science are landscapes of scientific research fields created by
quantitative analysis of bibliographic data. In such maps the 'cities' are, for instance,
research topics. Topics with a strong cognitive relation are in each other's vicinity and
topics with a weak relation are distant from each other. These maps have several
domains of application. As a policy supportive tool they can be applied to overview
the structure of a research field and to monitor its evolution. This book contributes to
the development of this application of bibliometric maps.CWTSFSW - CWTS - Ou
Bibliometric cartography of information retrieval research by using co-word analysis
The aim of this study is to map the intellectual structure of the field of Information Retrieval (IR) during the period of 1987-1997. Co-word analysis was employed to reveal patterns and trends in the IR field by measuring the association strengths of terms representative of relevant publications or other texts produced in IR field. Data were collected from Science Citation Index (SCI) and Social Science Citation Index (SSCI) for the period of 1987-1997. In addition to the keywords added by the SCI and SSCI databases, other important keywords were extracted from titles and abstracts manually. These keywords were further standardized using vocabulary control tools. In order to trace the dynamic changes of the IR field, the whole 11-year period was further separated into two consecutive periods: 1987-1991 and 1992-1997. The results show that the IR field has some established research themes and it also changes rapidly to embrace new themes
Improved lexical similarities for hybrid clustering through the use of noun phrases extraction
Clustering of hybrid document networks combining citation based links with lexical similarities suffered for a long time from the different properties of these underlying networks. In this paper we evaluate different processing options of noun phrases extracted from abstracts using natural language processing to improve the measurement of the lexical component. Term shingles of different length are created from each of the extracted noun phrases. We discuss twenty different extraction-shingling scenarios and compare their results. Some scenarios show no improvement compared with the previously used single term lexical approach used so far. But when all single term shingles are removed from the dataset the lexical network has properties which are comparable with those from a bibliographic coupling based network. Next, hybrid networks are built based on weighted combination of the two types of similarities with seven different weights. We demonstrate that removing all single term shingles provides the best results at the level of computational feasibility, comparability with bibliographic coupling and also in a community detection application
Electronic Commerce Research Profiles: Comparing E-Commerce and Information Systems Journals
The rapid diffusion of information and mobile technologies has revolutionized the way we do business and how we conduct our daily lives. Electronic commerce (e-commerce or EC) has had an enormous impact on business practices and has become a new area of study for researchers in related fields. Thousands of papers on this subject have been published in the past two decades, most of which have been published in e-commerce (EC) journals. However, many such papers have been published in information systems (IS) journals. Information systems have become the core discipline that drives e-commerce research. The purpose of this research is to report on the profiles of e-commerce papers published in major EC and IS journals, and to determine whether papers that have appeared in EC journals differ from those published in IS journals. We surveyed EC papers published in ten major journals and conducted a bibliometric analysis. Our findings indicate that (1) more EC papers are published in EC journals, but papers published in IS journals are cited more often; (2) collectively, authors in the U.S. are the most prolific, followed by those in China and Taiwan; (3) more theories were used in recent papers than in earlier ones, and the TAM has been the most popular model; (4) B2C and consumer behavior have been the most popular subject areas for EC research; and (5) the core knowledge measured by the co-citation network was provided by the same group of authors in EC and IS journal publications.

Patent Citation Analysis and Its Value in Research Evaluation: A Review and A New Approach to Map Technology-Relevant Research
Purpose:
First, to
review the state-of-the-art in patent citation analysis, particularly characteristics of patent citations
to scientific literature (scientific non-patent references,SNPRs). Second, to present a novel
mapping approach to identify technology-relevant research based on the papers cited
by and referring to the SNPRs.
Design/methodology/approach:
In the review
part we discuss the context of SNPRs such as the time lags between scientific
achievements and inventions. Also patent-to-patent citation is addressed
particularly because this type of patent citation analysis is a major element
in the assessment of the economic value of patents. We also review the research
on the role of universities and researchers in technological development, with
important issues such as universities as sources of technological knowledge and
inventor-author relations. We conclude the review part of this paper with an
overview of recent research on mapping and network analysis of the science and
technology interface and of technological progress in interaction with science.
In the second part we apply new techniques for the direct visualization of the cited
and citing relations of SNPRs, the mapping of the landscape around SNPRs by bibliographic
coupling and co-citation analysis, and the mapping of the conceptual
environment of SNPRs by keyword co-occurrence analysis.
Findings:
We discuss
several properties of SNPRs. Only a small minority of publications covered by the Web of Science or
Scopus are cited by patents, about 3%–4%. However, for publications based on
university-industry collaboration the number of SNPRs is considerably higher,
around 15%. The proposed mapping methodology based on a “second order SNPR approach”
enables a better assessment of the technological relevance of research.
Research
limitations: The main
limitation is that a more advanced merging of patent and publication data, in
particular unification of author and inventor names, in still a necessity.
Practical
implications: The proposed
mapping methodology enables the creation of a database of technology-relevant
papers (TRPs). In a bibliometric assessment the publications of research
groups, research programs or institutes can be matched with the TRPs and thus
the extent to which the work of groups, programs or institutes are relevant for
technological development can be measured.
Originality/value:
The review part
examines a wide range of findings in the research of patent citation analysis. The
mapping approach to identify a broad range of technology relevant papers is
novel and offers new opportunities in research evaluation practices.

Upowszechnianie wyników badań naukowych w międzynarodowych bazach danych : analiza biometryczna na przykładzie nauk technicznych, ze szczególnym uwzględnieniem elektrotechniki
The issues of bibliometrics, scientometrics, informetrics and webometrics have an important
place among research subject undertaken by Polish and foreign scholars. Initially,
these notions were used only by researchers in the fields of library science, scientometrics
and information science. However, at the turn of the 20th and 21st centuries, quantitative
methods became a fundamental tool for evaluation of, among others, sources of academic
communication, academic research, research and academic centers. One of the elements of
the evaluation is a quantitative analysis of academic publications in databases with international
access. It is of particular importance in the case of technical sciences. This work is
an attempt at a quantitative analysis of publications by Polish authors (affiliated to Polish
technical universities) and Polish journals on electrotechnics in international databases. The
contents are organized into four chapters with an introduction, conclusions, bibliography,
name index and a list of figures and illustrations. Chapters one and two are devoted to
theoretical issues, whereas chapters three and four – to practical issues.
In the first chapter, selected issues concerning quantitative methods were presented,
including an analysis of literature and a discussion over terminology carried out in book
publications and journals. Moreover, selected examples of research conducted with the use
of quantitative methods (including rankings and scientific reports) were discussed in this
chapter). In chapter two, sources of information on academic publications, their origins
and development (from bibliographic bases to citation indexes) were presented. A separate
subchapter was devoted to databases of academic publications created by libraries of technical
universities, and to indicators in the assessment of academic publications.
Chapter three deals with electrotechnics as a field of science. An analysis was conducted
with regard to the place of electrotechnics in science classifications based on selected
examples, and the development of the teaching of electrotechnics at university level was
shown. In this chapter, early and contemporary Polish journals on electrotechnics were
presented, including journals published by technical universities themselves.
Chapter four contains the results of an analysis of international databases (Scopus,
WoS, CC), focusing on the representation of Polish journals, including their citations, and
publications of authors with affiliation to Polish technical universities. Final conclusions of research and analyses have brought an answer to questions raised
with regard to the assessment of representation in international databases of publications
by Polish authors affiliated to Polish technical universities (in its various aspects, e.g.,
a publication type, language of publication, publication dynamics taking into account years
of publications, cooperation with representatives of other European and non-European
countries), and of Polish journals
