In plain terms

Shared text-feature library used by other transcript-* families (tone, exec-uncertainty, Q&A combativeness). Not a tradable alpha on its own.

How it works

Shared text-feature library (not a tradable family) used by other transcript-* families (tone, exec-uncertainty, guidance-shift, qa-combativeness). Provides a curated ~300-word subset of Loughran-McDonald (2011) positive/negative finance terms + speaker-role regex helpers (CEO/CFO vs analyst). The full ~4k-word LM dict can be wired in via a CSV at our data pipeline if production-grade scoring is needed.
