Concept - Word Sense Disambiguation

Word Sense Disambiguation (WSD)

Definition (s.370): the problem of identifying the intended word sense in a given context. Many words have multiple senses; e.g. verb appeal: (1) take a court case to a higher court for review, (2) request earnestly, (3) be attractive to.

As classification (s.371-372): tell living plants from manufacturing plants using context. The instance is the target word plus its context; the label $y$ is the sense; features are the context words paired with the label:

$f((plant,\text{The endangered plants play an ...}),y)=\{(the,y):1,(endangered,y):1,(play,y):1,(an,y):1,\dots \}$

Motivating humorous headlines (s.369): “Kids make nutritious snacks”, “Milk drinkers turn into powder”, “Man struck by lightning faces battery charges”.
