Vector arithmetic applies addition, subtraction, and related operations to word embeddings. In Word2Vec, these operations turn relationships between words into geometric displacements. section 6.3.1
A typical analogy calculation works like this:
- Subtract the vector for one city from its associated sports team. section 6.3.1
- Add that displacement to another city’s vector. section 6.3.1
- Find the vocabulary vector closest to the resulting point, since the exact result usually is not itself a word vector. section 6.3.1
Sports-team analogy
Portland Timbers + Seattle − Portland ≈ Seattle Sounders. The calculation transfers the city-to-team relationship through embedding space, supporting analogy questions in search, chatbots, and question-answering systems. section 6.3.1
Portland Timbers + Seattle - Portland = ?
