Configuration Reference

All settings can be overridden with environment variables — no code changes needed.

Setting	Environment Variable	Default
OpenAI API Key	OPENAI_API_KEY	None
Groq API Key	GROQ_API_KEY	None
Anthropic API Key	ANTHROPIC_API_KEY	None
Embedding Provider	SEMANTICA_EMBEDDING_PROVIDER	"openai"
Graph Backend	SEMANTICA_GRAPH_BACKEND	"networkx"
Log Level	SEMANTICA_LOG_LEVEL	"INFO"
Log Format	SEMANTICA_LOG_FORMAT	"text"

Troubleshooting

ModuleNotFoundError: No module named 'semantica'

Verify installation and that the correct Python environment is active:

pip list | grep semantica
pip install --upgrade semantica

For optional features, install the relevant extra:

pip install "semantica[llm-openai]"   # OpenAI provider
pip install "semantica[gpu]"          # GPU acceleration

AuthenticationError

Set your API key as an environment variable — never hardcode keys in source files:

export OPENAI_API_KEY="sk-..."
export GROQ_API_KEY="gsk_..."

MemoryError or OOM crashes

Switch from the default in-memory NetworkX backend to a persistent graph database:

from semantica.graph_store import FalkorDBStore
from semantica.kg import GraphBuilder

store   = FalkorDBStore(host="localhost", port=6379)
builder = GraphBuilder(merge_entities=True, graph_store=store)

Also reduce batch sizes and enable streaming ingestion for large corpora.

Slow processing on large datasets

Enable parallel execution and GPU acceleration:

from semantica.pipeline import Pipeline

pipeline = Pipeline(workers=8, batch_size=32)
pipeline.run(sources)

pip install "semantica[gpu]"  # CUDA-backed embeddings

Windows [all] installation fails

Fixed in v0.5.0. Upgrade:

pip install --upgrade semantica

Or install extras individually: pip install "semantica[core]", then add [llm-openai], [gpu], etc. as needed.

cp1252 encoding crash on Windows

Fixed in v0.5.0. For earlier versions, pass encoding explicitly or set the environment variable:

set PYTHONIOENCODING=utf-8

Performance Optimization

Backend Selection

Operation	NetworkX (default)	Neo4j / FalkorDB
Graph construction	Fast	Moderate
Query performance	Moderate	Fast
Scalability	Low — in-memory only	High — persistent
Recommended for	Development, small graphs	Production, large corpora

Use NetworkX for local development and prototyping. Switch to a persistent backend before deploying to production.

Batch Processing

Process documents in batches rather than one at a time. Configure chunk_size based on available RAM — a good starting point is 1,000 documents per batch on a 16 GB machine.

Deduplication v2

If deduplication is a bottleneck, switch from v1 strategies to v2:

resolver = EntityResolver()
merged   = resolver.resolve(entities, strategy="semantic_v2")  # up to 7x faster

Security Best Practices

• API keys — store in environment variables or a secrets manager; never commit them to version control; rotate on a schedule
• Sensitive data — use local embedding models (Ollama, HuggingFace) for PII or classified content; avoid sending sensitive data to external APIs without data handling agreements
• Graph exports — encrypt sensitive exports at rest; use the v0.5.0 SSRF-safe base_url validation when configuring custom LLM gateways
• XML ingestion — always use XMLIngestor (v0.5.0), which uses the XXE-safe lxml backend; never parse untrusted XML with the standard library parser
