Knowledge Base

A knowledge base is a central component in expert systems and rule-based architectures. It stores domain knowledge, facts, relationships, rules, and structures needed for decision support in an organized way. A strong knowledge base enables the system not only to store information but to perform inference with it. In modern AI, the idea is not limited to classical systems; RAG architectures, enterprise knowledge systems, and semantic search frameworks also rely on related logic. A knowledge base is one of the most structured answers to the question: “What does the system know?”
