This extension facilitates the computation of BIP! Scholar research-level impact indicators.

Example usage

This example demonstrates how to use the ScholarIndicators class to compute various researcher-level scholarly indicators based on sample data. It implements the following indicators:

• Work Types Count: Counts the number of works (papers, datasets, software, etc.).
• Total Citations: Sums up the total citation count across all works.
• h-Index & i10-Index: Computes the h-index and i10-index based on citation counts.
• Popularity, Influence, and Impulse Scores: Sums the popularity, influence, and impulse scores for all works.
• Popular & Influential Works Count: Counts popular and infuential works (i.e., those that have impact class other than the lowest one).
• Open Access Papers Percentage: Calculates the percentage of open access papers.
• Academic Age: Computes the academic age based on the earliest paper.
• Responsible Academic Age: Considers periods of inactivity to adjust academic age.
