Knowledge bases
Organized collections of information that AI systems can access to answer questions or perform tasks.
Think of knowledge bases as specialized digital libraries. Instead of just storing documents, they organize information in a way that AI can understand and use. This helps AI systems provide more accurate and relevant answers.
For example, a company might create a knowledge base with all its product manuals and customer support FAQs. When a customer asks a question about a product, the AI can quickly search this knowledge base to find the right answer, rather than just guessing or making up information.
Knowledge bases are structured repositories of information, often comprising facts, rules, and relationships, designed for efficient storage, retrieval, and reasoning by AI systems. They can range from simple databases of facts to complex ontologies representing domain-specific knowledge.
Effective knowledge bases allow AI agents to ground their responses in verified information, reducing hallucinations and improving task performance. Tradeoffs involve the effort required for knowledge acquisition, maintenance, and ensuring the knowledge base remains up-to-date and relevant to the AI's operational domain.
Microsoft Copilot is enhancing its agents with new capabilities for grounding, which relies on robust knowledge bases. This focus on better agent context suggests a push towards more informed and reliable AI interactions, making the underlying knowledge management systems increasingly important.

The concept of knowledge bases in AI has roots in early expert systems and symbolic AI research, aiming to codify human knowledge for machine reasoning. The term became more prominent with the development of AI systems designed to manage and query large amounts of information.
Ask Microsoft Copilot a question about a specific Microsoft product or service, like 'What are the latest features in Microsoft Teams?' Observe how it provides an answer that seems to draw from specific product information. You can also try asking it to summarize a document you provide, which often involves it accessing the document as a temporary knowledge base.

Questions people ask
- How do AI systems use knowledge bases?
- AI systems query knowledge bases to retrieve facts, rules, or context. This helps them generate more accurate, relevant, and grounded responses.
- What's the difference between a knowledge base and just giving an AI lots of text?
- Knowledge bases are structured and organized for efficient retrieval and reasoning, unlike a large block of unstructured text which the AI might struggle to effectively search and utilize.
