Country over-citation ratios

There is a clear tendency for authors of scientific papers to over-cite the papers by their fellow countrymen (and countrywomen) relative to the percentage presence of their papers in world output in the same field. We investigated the Over-Citation Ratio (OCR) as a function of this percentage, and the effects of different scientific fields and publication years. For cancer...

Lung cancer researchers, 2008–2013: their sex and ethnicity

This paper describes the process by which almost all authors of papers in the Web of Science (WoS) can be characterised by their sex and ethnicity or national background, based on their names. These are compared with two large databases of surnames and given names to determine to which of some 160 different ethnic groups they are most likely to belong. Since 2008 the authors of...

Mapping research activity on mental health disorders in Europe: study protocol for the Mapping_NCD project

Background Mental health disorders (MHDs) constitute a large and growing disease burden in Europe, although they typically receive less attention and research funding than other non-communicable diseases (NCDs). This study protocol describes a methodology for the mapping of MHD research in Europe as part of Mapping_NCD, a 2-year project funded by the European Commission which...

European Non-Communicable Respiratory Disease Research, 2002-13: Bibliometric Study of Outputs and Funding

This study was conducted in order to map European research in chronic respiratory diseases (CRDs). It was intended to assist the European Commission and other research funders to identify gaps and overlaps in their portfolios, and to suggest ways in which they could improve the effectiveness of their support and increase the impact of the research on patient care and on the...

Definition of Cancer Research: Journals, Titles, Abstracts or Keywords?

Three versions of a ‘filter’ used to identify papers on cancer research, as defined by Cancer Research, UK, and interpreted by four experts, have been compared. The first filter was based only on specialist journals and had unacceptably low recall. The second filter was based both on journals and on title words, and had both precision and recall above 0.9. The third filter was...

Global Cardiovascular Research Output, Citations, and Collaborations: A Time-Trend, Bibliometric Analysis (1999–2008)

Introduction Health research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide. Materials and Methods We...
