ThemeGraph: Semantic Representation Authorization for Directed Text-Analytic Graphs

Year: 2026

Type: preprint

Abstract: ThemeGraph is a representation-authorization architecture for human-facing directed text-analytic graphs. At claim time, one policy declared, typed certificate jointly governs the statement, graphical mark, requested-claim export, independently supported fallback, witness, and remediation. Asymmetric normalization of unordered co-occurrence can otherwise yield a numerically correct arrow without evidence of temporal, prerequisite, entailment, or causal direction. Participant-free evaluation compares four generated output-control conditions, removes contract distinctions, tests policy conformance and construct-boundary routes on five datasets, and evaluates a 24-configuration specification surface. All eight currently inventoried certificate-guarded output entry points require valid certificate state. These results establish bounded mechanism behavior, not policy validity, source truth, perceptual effectiveness, usability, analyst benefit, causal truth, or universal non-bypassability.
