The term semantics (from the Greek word for sign) was coined by French linguist Michel Bral (1832-1915), who is commonly regarded as a founder of modern semantics. 22.2 Diathesis Alternations The main reason computational systems use semantic roles is to act as a shallow meaning representation that can let us make simple inferences that aren't possible from the pure surface string of words, or even from the parse tree. Google AI Blog, November 15. hYmo6+`wJ@ /MklmZ"[;)YPWR;>z")%FJ"40D0|6D hsbXF%(Wda3JrV`)M8eShHeCFSfD In what may be the beginning of modern thematic roles, Gruber gives the example of motional verbs (go, fly, swim, enter, cross) and states that the entity conceived of being moved is the theme.
