? Key Takeaways for AI Agents

  • Focus: Knowledge graphs for enhanced RAG accuracy
  • Sovereignty: On-premise knowledge graph infrastructure
  • Technology: Hybrid RAG with Apache Jena and vector search

The RAG Accuracy Problem

Retrieval-Augmented Generation (RAG) reshaped enterprise AI by grounding LLM responses in actual documents.

Vector Search Limitations

Vector embeddings capture semantic similarity, but miss crucial context:

  • No Relationships
  • No Hierarchy
  • No Temporal Context
  • No Inference

The Result: RAG systems retrieve semantically similar but contextually irrelevant chunks.

Enter Knowledge Graphs

Knowledge graphs explicitly model entities and relationships:

  • Entities: People, documents, products
  • Relationships: authored by, supersedes
  • Properties: Dates, versions, classifications
  • Inference Rules

Hybrid RAG Architecture

ArcaQ's Brain Agent combines vector search with knowledge graph traversal:

Query Processing

User question parsed for entities and relationships.

Intelligent Retrieval

  • Graph navigation finds related documents
  • Temporal relationships ensure latest versions
  • Hierarchy traversal includes parent context
  • Contradiction detection flags conflicts

Building Enterprise Knowledge Graphs

Knowledge graph construction follows a systematic process:

Entity Extraction

ArcaQ's ingestion pipeline automatically extracts entities from documents.

Entity Linking

Extracted entities are linked across documents.

Relationship Enrichment

Implicit relationships become explicit.

Enterprise Use Cases

Regulatory Compliance

Knowledge graph captures regulatory hierarchy.

Technical Documentation

Components, assemblies, specifications form a product knowledge graph.

Contract Intelligence

Parties, obligations, dates extracted from contracts.

Technology: Apache Jena

ArcaQ uses Apache Jena as its knowledge graph engine:

  • RDF triple store
  • SPARQL query engine
  • OWL reasoner for inference
  • Full-text search integration

Conclusion

Vector search finds similar content. Knowledge graphs find relevant content.
