Patent US 5,587,903

A sentence entered by a user is translated into Esperanto. The translated sentence is then parsed and a series of propositions are generated. Each proposition consist of a subject, verb, and an optional object such as an adjective, noun, or prepositional phrase, if present. A series of propositional databases are used to relate the various propositions as to their function within the sentence, thereby mapping the thought of the sentence in a form recognizable by a machine.
