The pair tokens {(w n , w n+j ) : −t(n) ≤ j ≤ t(n), w i ∈ s} are then appended to the training data.
target/context training pairs are such that (i) only words within a k-window of the target are selected as context words for that target, and (ii) words closer to the target are more likely to be selected than those further away.
