GraphRAG in (Almost) Pure Cypher

GraphRAG is a method for using vector search to find relevant documents in a knowledge graph, with the goal of providing more accurate and reliable answers to questions. The author demonstrates this by building a graph of movies and TV series, and then uses GraphRAG to ask ChatGPT a question about Robb Stark's family, which it correctly answers based on the synopsis of a relevant document. However, when asked a question about a movie that was released after ChatGPT's training data, it hallucinates an answer instead of saying "I don't know". The author suggests using GraphRAG to improve the accuracy and reliability of AI-powered chatbots like ChatGPT by leveraging the power of knowledge graphs.
