Journal Impact Factors (JIFs) are widely used and promoted but have important limitations. In particular, JIFs can be unduly influenced by individual highly cited articles and hence are inherently unstable. A logical way to reduce the impact of individual high citation counts is to use the geometric mean rather than the standard mean in JIF calculations.(More)
Although various citation-based indicators are commonly used to help research evaluations, there are ongoing controversies about their value. In response, they are often correlated with quality ratings or with other quantitative indicators in order to partly assess their validity. When correlations are calculated for sets of publications from multiple(More)
Governments sometimes need to analyse sets of research papers within a field in order to monitor progress, assess the effect of recent policy changes, or identify areas of excellence. They may compare the average citation impacts of the papers by dividing them by the world average for the field and year. Since citation data is highly skewed, however, simple(More)
In this paper web issue analysis is introduced as a new technique to investigate an issue as reflected on the web. The issue chosen, Integrated Water Resource Management (IWRM), is a United Nations-initiated paradigm for managing water resources in an international context, particularly in developing nations. In common with many international governmental(More)
Hyperlinks between academic web sites, like citations, can potentially be used to map disciplinary structures and identify evidence of connections between disciplines. In this paper we classified a sample of links originating in three different disciplines: maths, physics and sociology. Links within a discipline were found to be different in character to(More)
National research impact indicators derived from citation counts are used by governments to help assess their national research performance and to identify the effect of funding or policy changes. Citation counts lag research by several years, however, and so their information is somewhat out of date. Some of this lag can be avoided by using readership(More)
When comparing the average citation impact of research groups, universities and countries, field normalisation reduces the influence of discipline and time. Confidence intervals for these indicators can help with attempts to infer whether differences between sets of publications are due to chance factors. Although both bootstrapping and formulae have been(More)
