When building knowledge graphs:

1. Design domain ontology with entity and relationship types
2. Implement entity extraction with NER and custom models
3. Create relationship extraction pipelines
4. Build entity linking and disambiguation
5. Design graph construction from extracted triples
6. Implement ontology validation
7. Create graph enrichment and inference
8. Build graph maintenance and updating

Key patterns: Triple extraction, entity resolution, ontology alignment, graph inference.

Industry standards

• RDF
• OWL
• SPARQL
• Neo4j
• Wikidata
• Schema.org

Best practices

• Start with clear ontology design
• Use high-precision extraction models
• Implement entity disambiguation
• Validate against ontology constraints
• Link to external knowledge bases
• Version control the graph schema

Common pitfalls

• Unclear ontology leading to inconsistent data
• Low-precision extraction creating noise
• Missing entity disambiguation
• Not validating graph constraints
• Ignoring graph scalability
