How can the overlap result be reproduced?

The result can be reproduced by building unique hostname sets per platform and recalculating pairwise Jaccard overlap after one explicit transformation.

What the data supports

  • Parse all 153,425 citation records with a standards-compliant CSV reader.
  • Build one unique hostname set for each of six platforms.
  • Calculate all 15 pairwise intersections, unions, and Jaccard values.
  • Lowercase each hostname, remove only a leading www prefix, and repeat.
BOUNDARY

Where the claim stops

Reproduction verifies the calculation against the supplied snapshot; it does not independently audit how the source dataset was collected.
