Text2Cypher Guide
Blog post from Neo4j
The article delves into the process of generating Cypher database queries from natural language using large language models (LLMs), specifically focusing on Text2Cypher for Neo4j graph databases. It explores the concept of Text2Query, which involves converting user input into database queries, and discusses the advantages and challenges of this process, such as handling domain-specific jargon and understanding database schemas. The article outlines when Text2Query should be used, highlighting its effectiveness in exploratory tasks and as a fallback tool. It also touches on various methods to improve the Text2Cypher workflow, such as context engineering, fine-tuning LLMs, and implementing validation-correction loops. Additionally, the article reviews several libraries and tools that support Text2Cypher workflows, including the Neo4j GraphRAG Python Package, LangChain Neo4j library, and Neo4j MCP servers, providing guidance on selecting appropriate tools based on specific use cases.
