Definition
A knowledge base serves as a digital library containing curated data, documents, or facts that AI systems can query to provide accurate, context-aware responses. In modern architectures like Retrieval-Augmented Generation (RAG), it bridges the gap between static pre-trained models and dynamic real-world information. By indexing external data sources, it allows language models to ground their outputs in verified facts, reducing hallucinations and enabling specialized domain expertise without requiring full model retraining.
