Chain for question-answering against a graph by generating Cypher statements.
Example
constchain = newGraphCypherQAChain({ llm:newChatOpenAI({ model:"gpt-4o-mini", temperature:0 }), graph:newNeo4jGraph(), }); constres = awaitchain.invoke("Who played in Pulp Fiction?");
Security
This chain will execute Cypher statements against the provided database.
Make sure that the database connection uses credentials
that are narrowly-scoped to only include necessary permissions.
Failure to do so may result in data corruption or loss, since the calling code
may attempt commands that would result in deletion, mutation of data
if appropriately prompted or reading sensitive data if such data is present in the database.
The best way to guard against such negative outcomes is to (as appropriate) limit the
permissions granted to the credentials used with this tool.
