P193 — AIEP — Evidence Knowledge Graph Integration Protocol

Publication Date: 2026-04-12 Status: Open Source Prior Art Disclosure Licence: Apache License 2.0 Author/Organisation: Phatfella Ltd Schema: AIEP_OS_SPEC_TEMPLATE v1.0.1 — https://aiep.dev/schemas/aiep-os-spec-template/v1.0.1

Field of the Invention

[0001] The disclosure relates to integration mechanisms connecting evidence artefact stores to knowledge graph structures in computing environments.

[0002] More particularly, the disclosure concerns an evidence knowledge graph integration protocol for use within an Architected Instruction and Evidence Protocol (AIEP) system, defining how evidence artefacts are projected as typed entities and relationships into an AIEP-managed knowledge graph, enabling structured graph-based retrieval and causal reasoning over evidence collections.

Framework Context

[0003] This invention operates within an Architected Instruction and Evidence Protocol (AIEP) environment as defined in United Kingdom patent application number GB2519711.2, filed 20 November 2025, the entire contents of which are incorporated herein by reference.

Summary of the Disclosure

[0004] A computer-implemented evidence knowledge graph integration protocol comprises: defining an EvidenceEntitySchema mapping evidence artefact fields to knowledge graph entity types and property vocabularies; on ingestion of each evidence artefact, executing an EntityExtractionPipeline that produces: one or more EvidenceEntityRecords (typed entities such as CLAIM, FACT, DATA_POINT, CONCEPT, EVENT) and zero or more EvidenceRelationshipRecords (typed edges such as CAUSED_BY, SUPPORTS, CONTRADICTS, IS_INSTANCE_OF); inserting extracted entities and relationships into the EvidenceKnowledgeGraph as governed graph operations carrying the source artefact’s EDID, TrustScore, and SensitivityTier; propagating artefact state changes to the knowledge graph — on RETRACTED or PROVENANCE_FAILED artefacts, marking associated graph entities as INVALIDATED; providing a GraphQueryInterface supporting SPARQL-compatible or property graph traversal queries bounded by caller’s access permissions; and computing EntityTrustScores for knowledge graph entities as weighted aggregates of the TrustScores of all contributing evidence artefacts.

[0005] The technical effect is modification of computing system behaviour by creating a live, governed semantic overlay of evidence artefacts as a queryable knowledge graph, improving structured reasoning and evidence retrieval.

Claims

[0007] A computer-implemented method for evidence knowledge graph integration comprising: extracting entities and relationships from evidence artefacts via EntityExtractionPipelines; inserting extractions into an EvidenceKnowledgeGraph with full provenance linkage; propagating artefact state changes to invalidate affected graph entities; computing EntityTrustScores as weighted TrustScore aggregates; and exposing a permission-bounded GraphQueryInterface.

[0008] A system for evidence knowledge graph integration comprising one or more processors and a non-transitory computer-readable medium storing instructions to execute the method of claim 1.
