The 2018 PBRF panel guidelines all mention the potential use of metrics or impact in the Evidence Portfolios. You can look at these mentions divided by each panel in the PDF document below. All of these mentions have been pulled directly from the TEC PBRF Panel-Specific Guidelines.
Research impact is not only about the quality of research but also how visible it is. The visibility and discoverability of research outputs are known to be a key factor in the frequency of citations and mentions.
A broad range of author, article, and journal metrics exist, and a number of tools are available providing access to different metrics, including Web of Science, Scopus and Google Scholar.
When and where could you be using metrics in your Evidence Portfolio?
All metrics require context. Every time you include a metric or impact measure in your Evidence Portfolio you need to provide information about which database, tool, or journal website you obtained it from. It could also be important to provide the year or subject category depending on the metric.
Not all metrics are created equal.
It is important to remember that where you obtain your metrics is very important. The citation dataset of these metrics aggregators are varied and sometimes unknown. Being aware of which dataset best represents your research outputs is the key to obtaining the metric which showcases your work in the best light.
