SciRah Score
A transparent score for researchers
The SciRah Score (0–100) summarises a researcher’s body of work from public data. Unlike scores that reward clicks or site activity, it only counts research outcomes — and the whole formula is published here.
The formula
Each part is turned into 0–100 points with the same curve, points = 100 × (1 − e^(−value ÷ k)), so early progress counts most and nobody can exceed 100. The parts are then combined with fixed weights:
| Part | Weight | Value | k |
|---|---|---|---|
| Citation impactHighly cited papers count much more, but no single paper can dominate. | 40% | Σ over papers of ln(1 + citations) × (0.5 + field percentile) | 400 |
| h-indexh papers with at least h citations each. | 20% | h-index | 25 |
| PublicationsSteady output counts, with diminishing returns. | 15% | total number of works | 150 |
| Research fundingFrom the funding acknowledgements recorded by OpenAlex. | 10% | distinct grants acknowledged in the papers | 10 |
| PatentsSelf-reported by the researcher on a verified profile. | 10% | patents granted | 5 |
| Graduated studentsSelf-reported on a verified profile; lower weight. | 5% | MPhil / PhD students supervised to graduation | 10 |
Why citations use a logarithm
A paper with 10,000 citations should never weigh the same as one with 10 — but it also shouldn’t be worth a thousand of them. With ln(1 + citations) a paper with 10 citations counts about 2.4 and one with 10,000 about 9.2.
Why fields are compared fairly
Medicine papers collect citations far faster than mathematics papers. Each paper is therefore weighted by its field percentile — how its citations compare with papers from the same field and year (from OpenAlex) — between ×0.5 and ×1.5.
What never counts
Likes, follows, profile views, comments or any other activity on SciRah. Those are easy to game and say nothing about research quality.
Claiming your profile
Researchers can verify their profile by signing in with ORCID (the ORCID iD must match the one linked to the profile). They can then add their patents and graduated students, which are shown as self-reported.
Like any single number, the score is a rough guide, not a judgement of a person’s research. Read their papers. Find a researcher.
