Citation analyses were performed for Australian social science journals to determine the differences between data drawn from
Web of Science and Scopus. These data were compared with the tier rankings assigned by disciplinary groups to the journals
for the purposes of a new research assessment model, Excellence in Research for Australia (ERA), due to be implemented in
2010. In addition, citation-based indicators including an extended journal impact factor, the h-index, and a modified journal diffusion factor, were calculated to assess whether subsequent analyses influence the ranking
of journals. The findings suggest that the Scopus database provides higher number of citations for more of the journals. However,
there appears to be very little association between the assigned tier ranking of journals and their rank derived from citations
data. The implications for Australian social science researchers are discussed in relation to the use of citation analysis
in the ERA.
