Human languages (e.g. English, Chinese, etc.) are one example of intelligent behaviour being studied within the field of computational intelligence. In my research, I investigate some of the common properties of languages, in particular English and Spanish, and demonstrate how these properties are integrated in a multilingual translation system. This system, written entirely in Prolog, translates texts between English and Spanish, in either direction, using rules of universal grammar, and utilizing a unification-based grammar formalism. I hope to show how universal principles of language structure, including morphology, syntax and semantics, can be exploited in the design of an actual natural language processing application, that of machine translation.
