Embedding

An embedding is a numerical representation of text (or other data) that captures its meaning in a form a computer can process and compare. When you convert a sentence into an embedding, similar sentences produce similar numbers — which allows AI systems to find conceptually related content, not just exact keyword matches. Embeddings are the technology behind semantic search, recommendation systems, and RAG.

For business users, embeddings are invisible — they're the mechanism that makes "search by meaning" possible in AI-powered knowledge management systems.
