Everything You Need for
Trustworthy AI Systems

Semantica provides the complete toolkit for building AI systems that are explainable, traceable, and production-ready. From context graphs to reasoning engines, every component is designed for transparency.

Context Graphs

The Foundation of Trustworthy AI

Build a structured, queryable graph of entities, relationships, and decisions. Causal, persistent, and fully traceable with temporal validity windows.

Entity ManagementTyped RelationshipsTemporal ValiditySPARQL Queries

Decision Intelligence

Track Every Choice, Trace Every Outcome

Record decisions as first-class objects with add_decision() and record_decision(). Find precedents, analyze impact, and maintain causal chains across your entire AI system.

Causal ChainsPrecedent SearchImpact AnalysisPolicy Engine

Full Provenance

W3C PROV-O Compliant Lineage

Every fact links back to its source with ProvenanceTracker. Algorithm provenance, graph builder provenance, and audit trails for compliance. No more mystery answers.

Source AttributionAlgorithm TrackingAudit TrailsExport to RDF

Reasoning Engines

From Rules to Explanations

Forward chaining with IF/THEN rules, Rete networks for high-throughput, deductive and abductive reasoning, and SPARQL for RDF. Every inference path is explainable.

Ontology Management

Schema-First Knowledge Engineering

Auto-generate OWL ontologies from your data, import existing schemas (OWL, RDF, Turtle, JSON-LD), validate with HermiT/Pellet, and generate SHACL shapes automatically.
