Embedding
also vector embedding
An embedding is a list of numbers (a vector) that represents the meaning of a piece of text, so that similar meanings produce numerically similar vectors.
Analogy
Like giving every sentence GPS coordinates where related ideas sit close together on the map.
Why it matters
Embeddings power semantic search and RAG, letting your automations find relevant knowledge by meaning instead of exact keyword matches.
In practice
"Cancel my booking" and "I want to end my reservation" land near each other as embeddings.
