Understanding Entity Authority Score (EAS)

A composite measure of entity authority across the four structural components of Byrum's Dominance Inequality, scored out of 100 points. Component I_E (Identity Completeness, 25 pts) measures structured data validity, authority database presence, and persistent identifier chains. Component A_E (Attribute Accuracy, 25 pts) measures structured data attribute correctness and corroboration. Component M_E (Machine Readability, 25 pts) measures structured data deployment and completeness. Component O_E (Ontological Authority, 25 pts) measures vocabulary attribution and lexicon ownership.

Frequently Asked Questions

What is the Entity Authority Score?

EAS is a composite measure of entity authority scored out of 100 points across four structural components: I_E (Identity Completeness, 25 pts), A_E (Attribute Accuracy, 25 pts), M_E (Machine Readability, 25 pts), and O_E (Ontological Authority, 25 pts).

What does each component measure?

I_E measures structured data validity, authority database presence, and persistent identifier chains. A_E measures attribute correctness and corroboration. M_E measures structured data deployment completeness. O_E measures vocabulary attribution and lexicon ownership.

How does EAS relate to CPQ?

EAS predicts CPQ behavior: scores below 40 correlate with Absent status (below reliable detection), 41–70 with Emerging (hedged citation), 71–85 with Cited (unhedged authority), and 86–100 with Defended (adversarially robust authority).
