Knowledge Graph
Core Facts
The Knowledge Graph was first proposed by Google in 2012 and used for search engine optimization.
Graph-based RAG can capture multi-hop reasoning relationships and is more precise than traditional RAG, which relies on similarity matching in vector databases.
Timeline (last 90 days)
Without relying on a vector database, agent memory can be implemented through alternative strategies such as TF-IDF/BM25 keyword retrieval, structured storage with inverted indexes, directly leveraging the LLM context window, or knowledge graphs.
