Master DeepSeek & Langflow Retrieval-augmented generation (RAG) is a reliable method for generating additional context for generative AI apps, but its effectiveness can vary depending on the type of data used. When source information consists of heavily interlinked documents, a knowledge graph can provide more accurate results than a vector database. A knowledge graph represents information as nodes and relationships between them, allowing for semantically relevant results to be found by traversing links between nodes. To build and store a knowledge graph, there are two standard models: Resource Description Framework (RDF) and property graphs. RDF-formatted graphs can be stored in an RDF triplestore, which offers benefits such as handling complexity at scale and being less costly to implement. In contrast, property graphs are typically stored in a graph database, offering flexibility but requiring additional development effort. However, leveraging existing vector databases like Astra DB or using tools like LangChain's GraphVectorStore can simplify the process without adding significant lift to the GenAI app infrastructure. By utilizing these approaches, developers can support GraphRAG without significantly changing their existing stack, resulting in more accurate results and improved performance.
