Longitudinal studies of web change are needed to assess the stability of webometric statistics and this paper forms part of an on-going longitudinal study of three national academic web spaces. It examines the relationship between university inlinks and research productivity over time and identifies reasons for individual universities experiencing significant increases and decreases in inlinks ...

webometrics, the quantitative study of Web-based phenomena (defined more precisely later) was born in 1997 (Almind and Ingwersen 1997) and was driven rapidly forward by a number of pioneering researchers and investigations (Aguillo 1998; Bar-Ilan 1999; Ingwersen 1998; Rodríguez and Gairín 1997; Rousseau 1997; Smith 1999) to establish itself as apparently the largest coherent field within librar...

There has been much recent interest in extracting information from collections of web links. One tool that has been used is Ingwersen’s Web Impact Factor. It has been demonstrated that several versions of this metric can produce results that correlate with research ratings of British universities showing that, despite being a measure of a purely Internet phenomenon, the results are susceptible ...

There are a variety of ranking systems for universities throughout the different continents of the world. The majority of the world ranking systems have paid special attention toward evaluation of universities and higher education institutions at the national and international level. This paper tries to study the similarities and status of top Asian universities in the list of top 200 universit...

Mike Thelwall, Statistical Cybermetrics Research Group, University of Wolverhampton, UK. Many different citation-based indicators are used by researchers and research evaluators to help evaluate the impact of scholarly outputs. Although the appropriateness of individual citation indicators depends in part on the statistical properties of citation counts, there is no universally agreed best-fitt...
