Package-level declarations

Types

object AlwaysProjectPolicy : ProjectionPolicy

Always project policy - useful for testing or when all propositions should be projected.

class DefaultProjectionPolicy(val confidenceThreshold: Double = 0.85, requireFullResolution: Boolean = true) : ProjectionPolicy

Default projection policy requiring high confidence and fully resolved entities.

EntityPairWithPropositions

data class EntityPairWithPropositions(val sourceId: String, val sourceName: String, val targetId: String, val targetName: String, val relationshipType: String, val propositions: List<Proposition>, val existingDescription: String?)

Input for batch relationship description synthesis.

GraphProjectionService

class GraphProjectionService(graphProjector: GraphProjector, persister: GraphRelationshipPersister, schema: <Error class: unknown class>, recordStore: ProjectionRecordStore? = null, reconciler: Reconciler = AlwaysCreateReconciler)

Bundles a GraphProjector, GraphRelationshipPersister, and DataDictionary together so you can project propositions to graph relationships and persist them in one call.

GraphProjector

interface GraphProjector : Projector<ProjectedRelationship>

Turns propositions into knowledge graph relationships, using the schema to validate relationship types and entity compatibility.

GraphRelationshipPersister

interface GraphRelationshipPersister

Persists ProjectedRelationship instances to a graph store.

LenientProjectionPolicy

class LenientProjectionPolicy(val confidenceThreshold: Double = 0.7) : ProjectionPolicy

Lenient projection policy that allows partial resolution. Requires at least subject and object mentions to be resolved.

LlmGraphProjector

data class LlmGraphProjector(ai: <Error class: unknown class>, relations: Relations = Relations.empty(), policy: ProjectionPolicy = DefaultProjectionPolicy(), llmOptions: <Error class: unknown class> = LlmOptions(), authorityResolver: AuthorityResolver = StructuralAuthorityResolver()) : GraphProjector

LLM-based graph projector. Uses an LLM to classify propositions into relationship types from both the DataDictionary schema and Relations predicates.

LlmRelationshipDescriptionSynthesizer

data class LlmRelationshipDescriptionSynthesizer(llmOptions: <Error class: unknown class>, ai: <Error class: unknown class>) : RelationshipDescriptionSynthesizer

LLM-based implementation of RelationshipDescriptionSynthesizer.

NamedEntityDataRepositoryGraphRelationshipPersister

class NamedEntityDataRepositoryGraphRelationshipPersister constructor(repository: <Error class: unknown class>, authorityResolver: AuthorityResolver = StructuralAuthorityResolver()) : GraphRelationshipPersister

Persists projected graph relationships via NamedEntityDataRepository.

ProjectedRelationship

data class ProjectedRelationship(val sourceId: String, val targetId: String, val type: String, val confidence: Double, val decay: Double = 0.0, val description: String? = null, val sourcePropositionIds: List<String>, val authority: AuthorityTier? = null) : RelationshipInstance, Projection

A graph relationship produced by projecting one or more propositions.

ProjectionPolicy

interface ProjectionPolicy

Determines whether a proposition should be projected to the graph. Projection creates relationships in the knowledge graph.

RelationBasedGraphProjector

class RelationBasedGraphProjector constructor(relations: Relations = Relations.empty(), policy: ProjectionPolicy = DefaultProjectionPolicy(), caseSensitive: Boolean = false, authorityResolver: AuthorityResolver = StructuralAuthorityResolver()) : GraphProjector

Graph projector that uses predicates from both the DataDictionary schema and Relations to determine relationship types.

RelationshipDescriptionSynthesizer

interface RelationshipDescriptionSynthesizer

Synthesizes a concise human-readable description for a relationship edge from the set of propositions that mention both entities.

RelationshipPersistenceResult

data class RelationshipPersistenceResult(val persistedCount: Int, val failedCount: Int, val errors: List<String> = emptyList(), val persistedRelationshipRefs: Set<String> = emptySet(), val failedRelationshipRefs: Set<String> = emptySet())

Result of persisting projected relationships.

SynthesisRequest

data class SynthesisRequest(val sourceEntityId: String, val sourceEntityName: String, val targetEntityId: String, val targetEntityName: String, val relationshipType: String, val propositions: List<Proposition>, val existingDescription: String? = null)

Input for relationship description synthesis.

SynthesisResult

data class SynthesisResult(val description: String, val confidence: Double, val sourcePropositionIds: List<String>)

Result of relationship description synthesis.
