... of these rulcs is to explicitly relate the semantic (sub)structures to possible syntactic counterparts. The rnappizJg pro- cess is driven by the semantic input structure that is traversed ... guided by semantic informa- tion in a top-down fashion. The benefits of integrated semantics are mani- fold. Elegant analyses of linguistic phenomena are possible that relate syntactic an...

Semantic networks ... knowledge representation. Several arguments have been made that frame representation languages and semantic- network languages are syntactic variants of the ftrst-order predicate calculus...
