LANGUAGE TRANSLATION USING A CONSTRAINED GRAMMAR IN THE FORM OF STRUCTURED SENTENCES FORMED ACCORDING TO PRE-DEFINED GRAMMAR TEMPLATES

Natural-language sentences are represented in accordance with a con-strained grammar and vocabulary structured to permit direct substitution of linguistic units in one language for corresponding linguistic units in another language. The vocabulary may be represented in a series of physically or logically distinct databases, each containing entries representing a form class as defined in the grammar. Translation involves direct lookup between the entries of a reference sentence and the corresponding entries in one or more target languages.
