Description
Return one shared-reference bibliographic-coupling contribution.
Bibliometric credit and citation indexes depend on corpus coverage, author/affiliation identity and a declared counting convention. A fractional contribution or index threshold describes supplied records without measuring research quality, causality or comparable scholarly impact across fields.
Return one shared-reference bibliographic-coupling contribution.
When to use this tool
Use Bibliographic Coupling One Reference Contribution when checking the stated bibliometric contribution, credit allocation or local index step.
How to use the tool and how it works
- Enter firstReferences, secondReferences, reference, fractionalWeight. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read shared, contribution. Inspect shared before interpreting the associated values.
Return one shared-reference bibliographic-coupling contribution. Require fractionalWeight >= 0; shared requires reference membership in both lists, contribution is its weight or zero.1

}Limitations and assumptions
- This checks one supplied reference, not a complete coupling score, co-citation network or source-quality measure.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified complete publication/citation data, identity resolution and a justified field/context-aware evaluation policy for research assessment.
