Software componentKnowledge & DataKnowledge & Dataarc:TextToGraphQueryTranslator

A software component that uses an LLM, grounded in the graph schema, to translate a natural-language question into an executable graph query.

Responsibility. Translates natural-language questions into schema-valid graph queries.

Also known as: Text2Cypher, Cypher Generator, NL-to-Cypher
