Most AI agents act without a trail.

They store embeddings, not meaning. They make decisions that cannot be audited, recall context that cannot be explained, and produce outputs that cannot be traced back to a source. Regulators, auditors, and enterprise risk teams are asking the same question: can you prove what your AI did and why?

Semantica is the Context and Accountability Layer that sits alongside your LLM and vector store — adding structured intelligence, causal reasoning, and a full audit trail to every decision your agents make.

Core capabilities:

• Context Graphs — structured, queryable graph of everything your agent knows, decides, and reasons about
• Decision Intelligence — every decision is a first-class object: traceable, searchable by precedent, causally linked
• AI Governance — policy enforcement, SHACL constraints, conflict detection, and compliance rule checks built in
• Full Auditability — W3C PROV-O provenance on every fact; audit trail exportable to JSON, CSV, or RDF
• Reasoning Engines — forward chaining, Rete network, Datalog, SPARQL — explainable paths, not black boxes
• Drop-in Integrations — Agno native, 12-tool MCP server, 50+ CLI commands, 109 REST endpoints, plugins for 8 editors

Quick Start

pip install semantica

from semantica.context import ContextGraph

graph = ContextGraph(advanced_analytics=True)

# Every agent decision becomes a queryable, auditable knowledge node
decision_id = graph.record_decision(
    category="vendor_selection",
    scenario="Choose cloud provider for HIPAA workload",
    reasoning="AWS offers BAA, mature HIPAA tooling, and existing team expertise",
    outcome="selected_aws",
    confidence=0.93,
)

# Ask "why did this happen?" and get a real, structured answer
chain     = graph.trace_decision_chain(decision_id)      # full causal ancestry
similar   = graph.find_similar_decisions("cloud vendor", max_results=5)  # precedents
impact    = graph.analyze_decision_impact(decision_id)   # downstream influence map
compliant = graph.check_decision_rules({"category": "vendor_selection"})  # policy check

Why Semantica

	Vector DB + RAG	Plain LLM Memory	Semantica
Recall method	Embedding similarity	Token window	Graph traversal + semantic search
Decision history	Not stored	Not stored	First-class queryable objects
Provenance	None	None	W3C PROV-O, source-linked
Reasoning	None	Black box	Forward chain, Rete, Datalog, SPARQL
Conflict detection	Silent overwrite	Silent overwrite	Detected, flagged, resolved
Time travel	No	No	Point-in-time graph snapshots
Compliance export	None	None	PROV-O, SHACL, OWL, RDF
Policy enforcement	None	None	Built-in rule engine + SHACL
Entity resolution	No	No	Blocking + semantic deduplication
Multi-agent context	Separate per agent	Separate per agent	Single shared intelligence layer

Semantica does not replace your LLM or your vector store — it adds the structured intelligence and accountability layer they cannot provide.

---

Context Graphs

A Context Graph is the structured memory layer that traditional RAG is missing. Instead of flat embeddings that answer "what is similar?", a Context Graph answers "what is connected, why, and how?"

Every entity, relationship, decision, and fact is a first-class node — queryable by graph traversal and neighbor expansion. Entities link to source documents. Decisions link to evidence and consequences. Facts carry full provenance. Conflicts are detected, not silently overwritten.

from semantica.context import ContextGraph, AgentContext
from semantica.vector_store import VectorStore

graph = ContextGraph(advanced_analytics=True)

# Add nodes and typed edges
graph.add_node("acme_corp",    "Organization", name="Acme Corp", industry="SaaS")
graph.add_node("alice_chen",   "Person",       name="Alice Chen", role="CTO")
graph.add_node("contract_001", "Contract",     value=2_400_000, currency="USD")

graph.add_edge("alice_chen", "acme_corp",    edge_type="works_for", since="2019-03-01")
graph.add_edge("acme_corp",  "contract_001", edge_type="party_to",  signed="2024-01-15")

# Graph traversal — hop through the graph from any node
neighbors = graph.get_neighbors("acme_corp", hops=2)

# Point-in-time snapshot — the graph as it existed on a past date
snapshot  = graph.state_at("2024-01-01")

# AgentContext — high-level API for agent memory workflows
vs  = VectorStore(backend="faiss")
ctx = AgentContext(vector_store=vs, knowledge_graph=graph)
ctx.store("Alice approved the Acme renewal in Q1 2024", conversation_id="conv_001")
retrieved = ctx.retrieve("who approved the Acme contract?")

Why graph over embeddings:

• Traversal finds connections embeddings miss — a person 3 hops from a contract
• Every node carries provenance — you can always ask "where did this come from?"
• Conflicts are detected and flagged before they corrupt your knowledge base
• Point-in-time snapshots let you replay history without reprocessing

---

Decision Intelligence

Decision Intelligence turns every AI choice from an ephemeral inference into a permanent, auditable, queryable record. It answers "what did your AI decide, why, and what happened next?" — the question regulators and enterprise risk teams ask with increasing frequency.

In Semantica, a decision is not a log line. It is a first-class graph node with a full lifecycle:

record_decision()          → stored as a graph node with full structured context
add_causal_relationship()  → linked to upstream causes and downstream effects
find_similar_decisions()   → semantic precedent search across all past decisions
trace_decision_chain()     → full causal ancestry back to root causes
analyze_decision_impact()  → downstream influence map — everything this decision affected
check_decision_rules()     → policy compliance gate against configurable rule sets
export / audit trail       → W3C PROV-O, CSV, or JSON for regulator submission

from semantica.context import ContextGraph

graph = ContextGraph(advanced_analytics=True)

# Record decisions with full structured context
app_id = graph.record_decision(
    category="credit_application",
    scenario="Personal loan — $85k income, 31% DTI, 3yr employment",
    reasoning="Income meets threshold; employment stable; no adverse credit events",
    outcome="proceed_to_underwriting",
    confidence=0.88,
    metadata={"applicant_id": "A-7291"},
)
uw_id = graph.record_decision(
    category="loan_underwriting",
    scenario="Underwriting review for A-7291",
    reasoning="DTI within policy; clean 36-month credit history",
    outcome="approved",
    confidence=0.94,
)
rate_id = graph.record_decision(
    category="interest_rate",
    scenario="Rate assignment for approved loan A-7291",
    outcome="rate_set_8.9pct",
    confidence=0.99,
)

# Build the auditable causal chain
graph.add_causal_relationship(app_id, uw_id,   relationship_type="triggers")
graph.add_causal_relationship(uw_id,  rate_id, relationship_type="enables")

# Query the intelligence
chain     = graph.trace_decision_chain(rate_id)
similar   = graph.find_similar_decisions("personal loan approval, 31% DTI", max_results=5)
impact    = graph.analyze_decision_impact(uw_id)
compliant = graph.check_decision_rules({"category": "loan_underwriting", "confidence": 0.94})

Knowledge Explorer

A browser-based graph workbench — pan and zoom live graphs, scrub the timeline, review every decision's causal chain, resolve duplicates, author your ontology visually. Built on React 19 + Sigma.js.

Workspace	What you can do
Knowledge Graph	Live Sigma.js canvas with ForceAtlas2 layout, Ego Mode, semantic distance heatmap
Timeline	Scrub through temporal events and watch the graph evolve
Decisions	Browse the causal chain behind every recorded decision
Registry	Live audit log of every graph mutation
Entity Resolution	Review and merge duplicates
Ontology Hub	SHACL Studio, visual editor, cross-ontology alignments, SKOS browser
Lineage	W3C PROV-O provenance visualization for any entity

python -m semantica.server              # backend on port 8000
cd explorer && npm install && npm run dev  # UI on port 5173
