Compositional Translation

Abstract

are each other's translation if they are built up from parts which are each other's translation, by means of translation-equivalent rules. Principle of Isomorphism: Two sentences are considered translations of each other if they have the same semantic derivation trees (hence corresponding syntactic derivation trees). Within this framework there is a close relation between syntax and semantics: the meaning of an expression is a function of the meaning of its parts, which, in turn are defined by syntax. The translation relation corresponds to the "tuning" of grammars I For example, it might be possible to include some programming problems at the end of each chapter that would allow the student to incrementally build a mini-translation system between two languages using the principles of the Rosetta approach. An additional instructional tool would be the provision of software for use in the development of such a system. 582 across language pairs, i.e., every lexical item and rule
