Semantic Role Labels (SRL)

Semantic Role Labels (SRL) is a system of semantic labels describing the roles of sentence participants: Agent (who does it), Predicate (what's done), Patient (to whom/what), Beneficiary (for whom), Instrument (with what), Location (where). Salience Hierarchy: Agent > Patient > Beneficiary > Instrument > Location. SRL has a weight of 0.10 in CQS.

The key principle is that if you want to increase an entity's Salience, set it as Agent. Change 'Cortisol is produced' (Patient) to 'Cortisol originates in the adrenal cortex' (Agent).

For example, the sentence 'Cortisol is produced by the adrenal cortex' promotes the adrenal cortex, not cortisol—because the cortex is the Agent.

In practice, use the Semantic Role Labels Parser skill on your article's lead and headings—check whether your Central Entity is Agent in >70% of key sentences. Knowledge of Semantic Role Labels (SRL) gives you an advantage over 99% of copywriters who don't know these mechanisms.
