Abstract: System with apparatus to improve international and other communication, and to provide easier access to data, especially digitized data, by means of linked alternative languages generated from a source language. As taught by the present invention, a linked alternative language is an especially designed language form quite different in outward format from its source language in that it has been optimized in a plurality of ways to allow targeted populations to comprehend and use it more efficiently than the source language, but which has also been carefully designed to retain full bidirectional machine translation equivalence to the source language. All use of artificial intelligence and computational linguistics for machine translation as taught in the present invention is constrained by these considerations.
