Quick Reference

Common Operations

The typical workflow involves these steps:

  1. Ingest documents using `FileIngestor`
  2. Parse documents using `DocumentParser`
  3. Extract entities and relationships using `NERExtractor` and `RelationExtractor`
  4. Build knowledge graph using `GraphBuilder`
  5. Generate embeddings using `TextEmbedder`

For complete examples, see: - Your First Knowledge Graph Cookbook: Complete workflow example - Welcome to Semantica Cookbook: All modules overview

Configuration Reference

Setting Environment Variable Config File Default
OpenAI API Key OPENAI_API_KEY api_keys.openai None
Embedding Provider SEMANTICA_EMBEDDING_PROVIDER embedding.provider "openai"
Graph Backend SEMANTICA_GRAPH_BACKEND knowledge_graph.backend "networkx"

Troubleshooting Guide

  • Import Errors --- ModuleNotFoundError

    Solution: Verify installation (pip list) and Python version (3.8+).

  • API Key Errors --- AuthenticationError

    Solution: Set OPENAI_API_KEY environment variable.

  • Memory Errors --- MemoryError

    Solution: Use batch processing and graph stores (Neo4j).

  • Slow Processing --- Long processing times

    Solution: Enable parallel processing and GPU acceleration.


Performance Optimization

1. Batch Processing

Process multiple documents together for better throughput. Use batch processing when working with large document collections.

For examples, see: - Data Ingestion Cookbook: Batch ingestion patterns - Multi-Source Data Integration Cookbook: Advanced integration

2. Parallel Execution

Use parallel processing for independent operations to improve performance on multi-core systems.

3. Backend Selection

Operation NetworkX Neo4j
Graph Construction ⚡⚡⚡ ⚡⚡
Query Performance ⚡⚡ ⚡⚡⚡
Scalability Low High

Security Best Practices

API Key Management

  • DO: Use environment variables, rotate keys regularly.
  • DON'T: Hardcode keys, commit to version control.

Data Privacy

  • DO: Encrypt sensitive data, use local models.
  • DON'T: Send PII to external APIs without protection.
