CORE DEFINITION
A word embedding maps each word to a dense, low-dimensional vector in a continuous space. It is trained from large corpora by exploiting co-occurrence statistics, such as which words appear in similar contexts. The result is that semantically close words sit close together geometrically, and relations between meanings can be approximated by arithmetic on the vectors, with the classic example that king minus man plus woman lands near queen. This turns discrete symbols into coordinates that downstream models can consume as features.
SCAFFOLDING EFFECT
Reduce cognitive load
- Calculate meaning: test semantic relatedness with cosine similarity instead of guessing from surface forms. - Reason by analogy: use vector arithmetic like king minus man plus woman to probe relations among concepts. - Feed downstream models: serve embeddings as input features for classification, clustering, retrieval, or translation.
Anchor fast decisions
The training objective forces words that share contexts to receive similar vectors, because the model must predict a word from its neighbors or vice versa. Over many examples, co-occurrence patterns leave a geometric trace: synonyms and topic siblings converge, while unrelated terms drift apart. Because the space is continuous and low-dimensional, similarity becomes a measurable distance and analogies become translations, which is why arithmetic on vectors approximates semantic relations.
