FIRME: Registry-Anchored Memory Graphs for Evolving, Heterogeneous Investor Knowledge
Financial memory breaks when the same fact arrives in new words. FIRME anchors observations to canonical identities: +7.8 to 12.1 points in correct match rate.
The claim
A registry keeps investor knowledge attached to one identity across periods.
The problem
Financial knowledge graphs split when the same fact arrives in new words.
Fragmented history stops evidence from accumulating.
How it works
Incoming observations reconcile to canonical relationships.
Each relationship keeps its source, time, and context.
A fixed product-topic ontology links calls to cash-flow signals.
Aliases send recurring observations to the same history.
Deterministic updates summarize reinforcement, inactivity, and reactivation.
Figures
What changes
Correct match rate rises 7.8 to 12.1 points over the baseline.
A blinded human audit finds 9.0 to 16.5 points of gain.
Reattachment recall improves by 22.5 to 29.0 points.
Limits
The evidence comes from proprietary records and S&P 500 transcripts.
Evaluation uses a fixed judge with fallback review.
The gains are measured against a single registry baseline.
