Knowledge Graph Construction from Decision Audit Trails: Entity Resolution and Temporal Edge Weighting for Governance Traceability

Transforming immutable decision records into queryable knowledge structures with principled temporal decay and cross-agent entity resolution

Enterprise governance platforms generate large audit trails that encode organizational decision-making, but those records are often difficult to query across multi-hop relationships. This paper presents a formal framework for constructing knowledge graphs from decision logs, including entity-resolution methods for noisy multi-agent audit data, temporal-decay functions for relevance-aware edge weighting, and compliance-oriented subgraph extraction. Experiments on MARIA OS audit corpora report 91.3% entity-resolution F1 across overlapping agent zones and 2.7x faster compliance-query response than relational baselines.

Auditable Financial Decision Traceability: Evidence Graph Models for Regulatory Compliance

Formal evidence graph construction and matrix-algebraic traceability for reconstructing every financial decision under SOX, Basel III, and MiFID II

Regulatory reconstruction of AI-driven financial decisions is difficult when logs are fragmented, timestamps drift, or causal links are missing. This paper introduces a formal evidence-graph model where each decision is an immutable node in a directed acyclic graph, linked by typed causal edges with cryptographic evidence bundles. We define `TraceCompleteness` as `TC = |reproducible decisions| / |total decisions|` and report `TC >= 0.997` across evaluated SOX, Basel III, and MiFID II audit scenarios.
