    Assessing the web connectivity of research groups on an international scale
    (Emerald, 2008) Thelwall, Mike; Li, Xuemei; Barjak, Franz; Robinson, Simon [in: ASLIB Proceedings]
    The purpose of this paper is to claim that it is useful to assess the web connectivity of research groups, describe hyperlink‐based techniques to achieve this and present brief details of European life sciences research groups as a case study. Design/methodology/approach A commercial search engine was harnessed to deliver hyperlink data via its automatic query submission interface. A special purpose link analysis tool, LexiURL, then summarised and graphed the link data in appropriate ways. Findings Webometrics can provide a wide range of descriptive information about the international connectivity of research groups. Research limitations/implications Only one field was analysed, data was taken from only one search engine, and the results were not validated. Practical implications Web connectivity seems to be particularly important for attracting overseas job applicants and to promote research achievements and capabilities, and hence we contend that it can be useful for national and international governments to use webometrics to ensure that the web is being used effectively by research groups. Originality/value This is the first paper to make a case for the value of using a range of webometric techniques to evaluate the web presences of research groups within a field, and possibly the first “applied” webometrics study produced for an external contract.

    Which factors explain the web impact of scientists personal homepages?
    (2007) Barjak, Franz; Li, Xuemei; Thelwall, Mike [in: Journal of the American Society for Information Science and Technology]
    In recent years, a considerable body of Webometric research has used hyperlinks to generate indicators for the impact of Web documents and the organizations that created them. The relationship between this Web impact and other, offline impact indicators has been explored for entire universities, departments, countries, and scientific journals, but not yet for individual scientists—an important omission. The present research closes this gap by investigating factors that may influence the Web impact (i.e., inlink counts) of scientists' personal homepages. Data concerning 456 scientists from five scientific disciplines in six European countries were analyzed, showing that both homepage content and personal and institutional characteristics of the homepage owners had significant relationships with inlink counts. A multivariate statistical analysis confirmed that full-text articles are the most linked-to content in homepages. At the individual homepage level, hyperlinks are related to several offline characteristics. Notable differences regarding total inlinks to scientists' homepages exist between the scientific disciplines and the countries in the sample. There also are both gender and age effects: fewer external inlinks (i.e., links from other Web domains) to the homepages of female and of older scientists. There is only a weak relationship between a scientist's recognition and homepage inlinks and, surprisingly, no relationship between research productivity and inlink counts. Contrary to expectations, the size of collaboration networks is negatively related to hyperlink counts. Some of the relationships between hyperlinks to homepages and the properties of their owners can be explained by the content that the homepage owners put on their homepage and their level of Internet use; however, the findings about productivity and collaborations do not seem to have a simple, intuitive explanation. Overall, the results emphasize the complexity of the phenomenon of Web linking, when analyzed at the level of individual pages.

    From the analogue divide to the hybrid divide: the internet does not ensure equality of access to information in science
    (Idea Group, 2006) Barjak, Franz; Hine, Christine [in: New Infrastructures for Knowledge Production: understanding e-science]
    New Infrastructures for Knowledge Production: Understanding E-Science offers a distinctive understanding of new infrastructures for knowledge production based in science and technology studies. This field offers a unique potential to assess systematically the prospects for new modes of science enabled by information and communication technologies. The authors use varied methodological approaches, reviewing the origins of initiatives to develop e-science infrastructures, exploring the diversity of the various solutions and the scientific cultures which use them, and assessing the prospects for wholesale change in scientific structures and practices. New Infrastructures for Knowledge Production: Understanding E-Science contains practical advice for the design of appropriate technological solutions, and long range assessments of the prospects for change useful both to policy makers and those implementing institutional infrastructures. Readers interested in understanding contemporary science will gain a rich picture of the practices and the technologies that are shaping the knowledge production of the future.
