agent event goal Simple Definition An event is an action over time of an agent toward a goal. Examples (English) • The man approaches the chair. • The cat sat on the mat.

Semantic Role agent Definition event goal Definition Agent is the semantic role of a person or thing. Goal is the semantic role of the place to who is the doer of an event. which something moves, or the thing toward which an action is directed. Examples (English) • The boy ran down the street. • He was chased by the dog. • John swam to the raft. • He threw the book at me. source: http: //www. sil. org/linguistics/Glossary. Of. Linguistic.
