Research impact and PBRF

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. 

Metrics in PBRF Evidence Portfolios

When and where could you be using metrics in your Evidence Portfolio? 

  • When describing your own personal impact (Supporting Information)
  • When describing the impact of one of your research outputs (NRO)
  • When describing the impact of a journal you have published in/reviewed for/act as an editor for (NRO/Research Contribution)
  • When describing the impact of past Research Outputs that have accumulated recognition over time (Research Contribution)

How to use metrics

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. 

Metric methodology

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.

  • Web of Science covers a curated database encompassing over 50,000 scholarly books, 12,000 journals and 160,000 conference proceedings. There is a strong representation of traditional science disciplines.
  • Scopus covers over 120,000 books and nearly 22,000 titles from over 5,000 publishers, of which 20,000 are peer-reviewed journals in the scientific, technical, medical, and social sciences (including arts and humanities)
  • Google Scholar does not publish information on the scope of its coverage, but does provide the largest coverage across all disciplines including all sources that it can access, regardless of reputation or quality.
