Correlation of Impact Measures of Institutional Repositories and PBRF Ranking
This study examines the correlation of website impact factor of institutional repositories (IR) of all eight universities in New Zealand and the Performance Based Research Fund (PBRF) quality score. The purpose of the research is to find out whether there is correlation between these two figures. The research problems are: the correlation between the IR homepage ranking and the PBRF quality score, the correlation between the IR website inlinks and the PBRF quality score, and the correlation between the IR website impact factor and the PBRF quality score. The research also studied the different web ranking tools and tried to find out whether these tools can be used to measure the quality of IR documents. The research used Yahoo Site Explorer to collect information of inlinks and also use other tools to collect the webpage ranking. The finding of this research are that there is small correlation between the IR website impact factor and PBRF quality score, and the page ranking is not a good tool to exam the quality of IR document as a whole.
