Can prompts help build lightweight knowledge graphs?
Yes—use prompts to extract entities and relations from documents into a defined schema. Provide examples, controlled vocabularies, and disambiguation rules. Validate outputs and merge with existing nodes carefully to avoid duplicates.
In practice
Start with one relation type and expand once accuracy stabilizes.
Where to start
- [01]Define entities, relations, and IDs.
- [02]Extract from a small corpus and validate.
- [03]Deduplicate with similarity thresholds.
- [04]Iterate schema based on real use.
