SciVal Metric: Outputs in Top Views Percentiles

Back to all metricsOutputs in Top Views Percentiles in SciVal indicates the extent to which an entity’s publications are present in the most-viewed percentiles of a data universe: how many publications are in the top 1%, 5%, 10% or 25% of the most-viewed publications?
The entire Scopus database, or “World”, is the default data universe used to generate this metric:
- The view counts that represent the thresholds of the 1%, 5%, 10% and 25% most-viewed papers in Scopus per Publication Year are calculated. Sometimes the same number of views received by the publication at, say, the 10% boundary has been received by more than 10% of publications; in this case, all of the publications that have received this number of views are counted within the top 10% of the Scopus data universe, even though that represents more than 10% by volume.
- SciVal uses these view thresholds to calculate the number of an entity’s publications that fall within each percentile range.
Use of the Publication Type filter affects the publications in the data universe that are used to generate the view thresholds, as well as the publications of the entity upon which the calculation is performed.
When field-weighting Outputs in Top Views Percentiles, the document views ratio is used instead of views to compute values for each percentile. The rest of the calculation remains the same as the calculation for the Field-Weighted Citation Impact. The value displayed in the chart or table view is the number of outputs that meet the benchmark, so contrary to the Field-Weighted Citation Impact, the field-weighted value for Outputs in Top Views Percentiles will not be near 1.00.
- Benchmark the contributions towards the most influential, highly viewed publications in the world of entities of different sizes, but in similar disciplines
- It is advised to select the 'Percentage' option when comparing entities of different sizes, to normalize for this variable
- Distinguish between entities whose performance seems similar when viewed by other metrics, such as Scholarly Output, Views per Publication, or Collaboration
- Showcase the performance of a prestigious entity whose publications are amongst the most viewed and highly visible publications of the scholarly world
- Comparing entities in different disciplines:
- It is not advisable to use this metric to compare entities in distinct disciplines without accounting for these differences.
- When comparing entities made up of a mixture of disciplines, such as an Institution or Country, it is advised to apply the Research Area filter to focus on one field that is common between all the entities.
- Trust needs to be built in the metrics in SciVal. The views thresholds may depend on the entire Scopus database, and it will be difficult for a user to validate these boundaries. Users are advised to select simpler metrics, such as Views per Publication, if trust in the accuracy of the SciVal calculations needs to be built.
- Views per Publicationopens in new tab/window, which indicates the average usage impact of an entity’s publications
- The set of all other “Power Metrics” whose value tends to increase as the entity becomes bigger: Scholarly Output, Subject Area Count, Scopus Source Title Count, Citation Count, Cited Publications (“Total value”), Number of Citing Countries, Collaboration (“Total value”), Academic-Corporate Collaboration (“Total value”), Publications in Top Journal Percentiles (“Total value”), and h-indices
- The set of “time-independent metrics”, which provide useful, reliable information immediately upon publication and do not rely on the passing of time for useful data to accumulate: Scholarly Output, Subject Area Count, Scopus Source Title Count, Collaboration, Academic-Corporate Collaboration, and Publications in Top Journal Percentiles
