Vector Embedding
A technique that maps text or other data into high-dimensional floating-point vectors, where semantically similar content is located in closer proximity within the vector space. It forms the core mathematical foundation for semantic retrieval and natural language processing.

When similarity scores fall in an ambiguous range, relying solely on threshold cutoffs is prone to misjudgment, which is why a large language model is introduced as a judge to perform semantic reasoning.
AI semantic search typically relies on vector embedding technology at its core, encoding text and icon metadata as high-dimensional vectors and measuring semantic distance via cosine similarity.
