This conversion is done by a special AI approach called embedding—an AI agent extracts the meaning of a data element (a.k.a. semantics) and expresses it as an organized list of numbers (the embedding). The numbers represent a position in the space of all meaning and put the meaning of that data element in context with others. We refer to these organized lists of numbers as vectors. Related data elements (for example, a Lamborghini and a Ferrari) will have similar vectors and will be close to each other in the space of meanings. You can also imagine the vector as the semantic fingerprint of a data element, and just like the fingerprints...
