Engineering Prompts for
Knowledge Graph Generation

Knowledge Graphs (KGs) structure information into entities and relationships. Prompt Engineering is the lever that transforms unstructured text into these structured triples. Explore how advanced prompting techniques unlock the power of Graph AI.

Understanding the fundamental strategies for steering LLMs towards structured output. Click a card to see its application in Graph generation.

Zero-Shot Prompting

Asking the model to extract entities and relations without examples. relies entirely on the model's pre-training.

Few-Shot Prompting

Providing specific examples of Input-Text to JSON-Output pairs within the prompt context.

Strategy Guide

Actionable solutions for common KG generation challenges.

Challenge: Schema Hallucination

Model invents relationships (e.g., "likes") not defined in your ontology.

Solution: Inject the schema explicitly in the system prompt. Use "Constrained Decoding" if available, or list valid relations as a JSON enum.
Challenge: Coreference Resolution

Model fails to link "He" or "The company" back to the specific entity.

Solution: Add a pre-processing step prompt: "Rewrite the text replacing pronouns with specific entity names" before extraction.
Challenge: Invalid JSON Output

Model returns markdown text or malformed JSON that breaks parsers.

Solution: Use One-Shot prompting with a strict JSON example. Enforce output mode (e.g., GPT-4 JSON mode).
Challenge: Granularity Control

Model extracts too many trivial nodes or misses abstract concepts.

Solution: Define "Entity Types" strictly in the prompt (e.g., "Only extract People, Organizations, and Locations").
