Semantica – Open-source framework for semantic layers and decision intelligence

Summary: Semantica is an open-source framework that transforms unstructured data into structured knowledge graphs with provenance tracking, reasoning engines, and explainable decision pipelines. It integrates with AI frameworks like LangChain and LlamaIndex to enhance memory, reasoning, and traceability in AI agents.

What it does

Semantica builds context graphs from documents and raw text, tracks AI decisions with causal chains, and combines knowledge graphs, vector search, and rule engines to enable explainable reasoning.

Who it's for

It is designed for AI engineers and developers building AI systems requiring semantic intelligence and decision traceability.

Why it matters

It addresses the lack of meaning, decision tracking, and source traceability in AI agents by adding a semantic intelligence layer on top of AI stacks.
