Calculating composite indicators¶
The following examples showcase how different individual indicators can be combined to obtain further insight into the Dimensions data.
Note
These examples reflect the data at specific time point. Therefore we would expect the calculated values from the following queries to change over time, as the coverage of Dimensions data increases.
Calculating percentage of open access papers for a specific funder¶
In this example we first search for all publications funded by the National Cancer Institute (NCI) and filter for a specific type of open access. In this case we are selecting documents that have a version of the record that is free under an open licence from a full OA, also known as Gold Open Access.
search publications
where open_access_categories.name= "Pure Gold" and funders.name="National Cancer Institute"
return publications
From looking at the stats component of the returned data, we can see that there are 35858 documents that match this query. After that we need to determine what is the total publication output for the funder.
search publications
where funders.name="National Cancer Institute"
return publications
From the query above we get that there are 531281 publications associated with funding from the NCI. Finally by simply calculating the ratio between open access publications and all publications, we can conclude that 6.75% of the publications funded by the NCI are Gold Open Access.
Calculating publications per active grant for specific fields of research¶
The ratio of publications to active grants can provide insights across different disciplines and shed light on aspects obscured by funding amounts. To calculate this, it is necessary to perform a couple of queries and then manually calculate the ratio.
For the sake of simplicity, let us look into a 3 year funding period (2015-2017) for Monash University in Australia (grid.1002.3). Taking advantage of the fields of research categorisation system (FOR) we can line up specific fields of study across both publications and grants.
First, we search for all Monash University publications aggregated by field of research and published after the first active year of grant funding:
search publications
where research_orgs.id = "grid.1002.3" and year>=2015
return FOR
Next, we can select a couple of categories and store their publication output. After that we perform a similar search on those categories, but this time across grant content.
search grants
where research_orgs.id = "grid.1002.3"
and active_year in [2015:2017]
and FOR.name="1701 Psychology"
return active_year
As you can see from the query, we are looking at grants that were active between 2015 and 2017 for the same university in the field of psychology. The same can be done for another research area like pharmacology.
search grants
where research_orgs.id = "grid.1002.3"
and active_year in [2015:2017]
and FOR.name="1115 Pharmacology and Pharmaceutical Sciences"
return active_year
Based on these three queries we find that the number of grants for psychology and pharmacology are 193 and 148 respectively. However there is a significant difference in the number of publications, as we get 1896 for psychology and only 277 for pharmacology. Finally by calculating the ratio between grants and publication we can see in this case, that research in psychology produces approximately 5 times as many publications as its pharmacological counterpart.
