GraphRAG builds a Neo4j knowledge graph from 41,000 Skytrax reviews using Sentence-BERT embeddings, Cypher queries and a RAG layer with LLMs (tested with GPT-family and DeepSea), turning chunks of text into aspect nodes (seat comfort, cabin staff, in-flight entertainment) linked to Ekman-based emotions. Retrieval precision/recall and MRR run mostly above 90%, and a shown insight flags in-flight entertainment = 58% anger. The pipeline runs as a periodic or live stack and yields explainable, queryable aspect‑level emotion signals.
