Kelleni Index
(ARI²)

Author Research Integrity Risk Index

A free bibliometric screening tool for editors, publishers, and researchers. Enter an author's OpenAlex ID and the index calculates automatically from public data. Developed by Dr. Mina T. Kelleni, Minia University, Egypt.

What is ARI²

A composite bibliometric risk index

ARI² combines four public-record signals into a composite score. High scores flag statistically unusual publication patterns warranting human review — not automatic conclusions of misconduct. Validated in a retrospective pilot study of 28 authors. Always apply the due-process checklist before drawing any conclusion.

Signal A · 35%
Network Fragmentation
Co-authors ÷ Works
Weight: 35%
Paper-mill authors accumulate many unique co-authors per paper — mostly one-time collaborators from unrelated institutions. High values suggest transactional rather than collaborative authorship patterns.
Signal B · 25%
Retraction Burden
Retractions ÷ Works
Weight: 25%
Proportion of output formally retracted. Signal B makes full ARI² retrospective by design. Retractions are detected from OpenAlex is_retracted flags. Cross-check against Retraction Watch for high-stakes assessments.
Signal C · 20%
Output Anomaly
Works ÷ h-index
Weight: 20%
Paper-mill participants inflate work count without commensurate impact. Interpret cautiously for early-career researchers and specialized subfields where citation counts are structurally lower.
Signal D · 20%
Citation Integrity
(Works × h + 1) ÷ (Citations + 1)
Weight: 20%
Inverted citation density metric. High values flag hollow citation profiles. Not field-normalized in the current version — context review is essential.

How to Use

Step-by-step guide

The automatic lookup handles all data retrieval for you. The guide below explains how to find the OpenAlex Author ID and how to obtain co-author and retraction data manually if you prefer the manual entry mode.

1

Go to the Calculator section and type the author's name

In the Automatic Lookup tab of the calculator above, type the author's full name and click Search. The tool searches OpenAlex and returns matching author profiles.

Select the correct author from the results

Click on the matching author. Verify by checking the institution, field, and country. Multiple authors with the same name may appear — select the one whose profile matches the author you are assessing.

If the correct author does not appear in the results, try a different spelling, add the institution name, or use the Manual Entry mode with values obtained directly from openalex.org.

3

Click "Fetch Data and Calculate ARI²"

The tool automatically retrieves the author's full works list from OpenAlex, counts unique co-authors across all publications, counts retracted works, and calculates all four signals and the composite ARI² score. A progress bar shows the status for authors with large publication records.

What is computed automatically: Works count, Citations, h-index — from the author profile. Unique co-authors — by collecting all co-author IDs across all works and counting each person once. Retractions — by counting works where OpenAlex has flagged is_retracted = true.

No downloads, no exports, no manual counting needed.

Obtain the unique co-author count via the OpenAlex API

The unique co-author count is not displayed directly on the author profile page. It requires fetching the author's works data. The simplest method: copy the author ID from the page URL (the part starting with A followed by digits), then use the following API call in your browser address bar.

openalex.org/authors/A5023888391
Copy the Author ID from the URL — the bold part above
api.openalex.org/works?filter=authorships.author.id:A5023888391&select=authorships,is_retracted&per_page=200&cursor=*&mailto=your@email.com
Paste this URL in your browser, replacing the Author ID with the one you copied. The resulting JSON contains co-author IDs and retraction flags for all works. The automatic lookup mode does this for you.

Easier alternative: Use the Automatic Lookup mode. It performs this entire process for you and shows the co-author count before calculating the score.

Automatic Lookup is strongly recommended for all users.

When to use Retraction Watch

The Automatic Lookup mode detects retractions from OpenAlex's is_retracted field, which is the same source used in the original ARI² research. OpenAlex's retraction detection is not exhaustive — some retractions are indexed later than others. Retraction Watch is the most comprehensive retraction database and should be used to cross-check the result for high-stakes editorial assessments.

When to cross-check with Retraction Watch: When the automatic lookup returns a non-zero retraction count and you need to verify the exact number. When the automatic lookup returns zero but you have reason to suspect retractions exist. Before taking any formal editorial action based on a High score band result.

For routine screening, OpenAlex retraction data is sufficient. For formal proceedings, always verify against Retraction Watch.

Search the Retraction Watch Database

Visit retractionwatch.com/retraction-watch-database and search by the author's full name. Count the total retracted papers listed. If a discrepancy exists between OpenAlex and Retraction Watch, use the higher count and enter it manually using the Manual Entry mode.

Interpreting Results

What the score bands mean

ARI² scores are calibrated against the 28-author pilot cohort. Score bands are exploratory heuristics — not validated cut-offs. Every flag requires human review and contextual assessment before any decision is taken.

Low Score Band
0 – 33.3
No unusual bibliometric pattern detected relative to the pilot cohort. Standard editorial review applies. A low score does not exclude misconduct not captured by the four signals — particularly content fraud or selective data manipulation.
Moderate Score Band
33.3 – 66.7
One or more signals are elevated. This may reflect legitimately large collaboration networks, high-volume productive researchers, or genuine authorship irregularities. Consult the due-process checklist. Six high-output controls with verified zero retractions scored in this band in the pilot study.
High Score Band
66.7 – 100
Multiple signals significantly elevated relative to the pilot cohort. This pattern is consistent with commercial authorship or high retraction burden. Warrants structured editorial investigation using the due-process checklist. A high score is the beginning of an inquiry — not its conclusion.

Calibration caveat: Scores are normalized against the 28-author pilot cohort (Kelleni 2026) and are not yet externally validated. Authors whose profiles fall outside the pilot range may receive scores below 0 or above 100 — these should be read qualitatively. For the full open-source scoring pipeline, see the Zenodo repository. A validated reference population is under development.

Responsible Use

Due-process checklist

Any author receiving a Moderate or High score band flag must be reviewed against this checklist before any editorial action is taken. ARI² is a screening aid — the beginning of an inquiry, not its conclusion.

1

Verify author identity

Confirm via ORCID. Name disambiguation errors in OpenAlex can inflate co-author counts for authors with common names.

2

Review field context

Is high co-author count normal in this field? Large consortium science and clinical trial networks legitimately produce high Signal A values.

3

Assess career stage

Is the author early-career? High output may reflect a productive lab. Is the elevated signal recent or consistent across the full career?

4

Check retraction details

Are retractions from a single event or distributed across multiple journals and years? The pattern matters as much as the count.

5

Review co-author network

Do co-authors appear across many unrelated papers? Are many one-time collaborators from geographically and institutionally unconnected locations?

6

Examine journal patterns

Were many papers submitted to the same journal cluster or known predatory publishers? Unusual special-issue clustering warrants scrutiny.

7

Apply proportionate response

ARI² flags trigger full investigation — never automatic rejection. All decisions must follow institutional due-process procedures and allow the author to respond.

Ethical Considerations and Responsible Use

ARI² scores are probabilistic risk indicators, not determinations of misconduct. A high score reflects a statistically unusual publication pattern that warrants human review and contextual investigation — not automatic sanction. No author should face rejection, retraction, defunding, or any professional consequence based solely on an ARI² score. The index is a screening aid. Misuse of this index to make adverse decisions without adherence to due process would be both ethically unsound and legally perilous.
