About Semantica

Semantica is an open-source, graph-native context and decision intelligence engine designed for AI agents and regulated environments. It unifies enterprise knowledge sources—PDFs, databases, and APIs—into a single, queryable context graph with entity resolution and provenance tracking. At inference time, agents query the graph to retrieve verified context, apply rules, and produce decisions with explicit causal links and confidence scores. Every output is grounded in the graph, traceable through sessions, and auditable via exportable W3C PROV-O lineage. The system supports both RDF and property graphs with SPARQL and Cypher under a unified API, enabling hybrid GraphRAG retrieval that blends vector search and graph traversal. Semantica is built for engineering teams deploying agentic systems, data platforms, or RAG in regulated domains such as energy, finance, healthcare, legal, and public-sector contexts. It also serves startups needing auditable, multi-agent context without vendor lock-in. The platform includes a Knowledge Explorer for visual inspection, temporal audits, and decision audit trails, with deployment options ranging from VPC to on-premises environments. Developers can initialize a ContextGraph via Python API or REST/MCP server, choose storage backends like Neo4j or FalkorDB, and integrate vector stores such as FAISS or Weaviate for hybrid retrieval. The tool emphasizes regulatory Q&A, cross-session agent collaboration, and temporal audits comparing policies and outcomes over time, ensuring transparency and compliance in high-stakes workflows.

Frequently asked questions about Semantica

What does Semantica do?

Semantica is an open-source, graph-native context and decision intelligence engine that unifies enterprise knowledge into queryable context graphs. It enables AI agents to retrieve verified context, apply rules, and produce decisions with explicit causal links and confidence scores.

Who is Semantica designed for?

Semantica is designed for engineering teams deploying agentic systems, data platforms, or RAG in regulated domains such as energy, finance, healthcare, legal, and public-sector contexts. It also suits startups needing auditable, multi-agent context without vendor lock-in.

What are the pricing options for Semantica?

The core engine is free forever under the MIT license. Enterprise engagements are available for pilot and design-partner work, full on-prem or VPC deployment, and SLA-backed support, but the software itself does not force cloud usage.

Does Semantica integrate with existing vector stores?

Yes, Semantica supports hybrid retrieval by integrating vector stores such as FAISS or Weaviate alongside graph databases like Neo4j or FalkorDB through a unified API.

How do I get started with Semantica?

You can initialize a ContextGraph via Python API or REST/MCP server. Start by installing the package with 'pip install semantica' and explore the open-source core, documentation, and demo resources available on the website.

Can Semantica be deployed on-premises?

Yes, Semantica is designed for on-premises and VPC deployment, ensuring data never leaves your environment. It supports storage backends like Neo4j, FalkorDB, and RDF triple stores.
