This paper presents general methods for studying the problems of translatability between classes of schemes and equivalence of schemes in a given class. There are four methods: applying the theory of formal languages, programming, measuring the complexity of a computation, and "cutting and pasting." These methods are used to answer several questions of translatability and equivalence for classe...

This paper addresses the issues in designing the so-called ‘Controlled Korean’ for a Korean-English MT system. Controlled Language is a sublanguage of a natural language which is supposed to improve the readability and the translatability of a text. Much effort has been made to design a controlled language for major international languages such as English, German, Spanish and etc. However, litt...

We report on an experiment to test the efficacy of ‘controlled language’ authoring of technical documents in Japanese, with respect both to the readability of the Japanese source and the quality of the English machine-translated output. Using four MT systems, we tested two sets of writing rules designed for two document types written by authors with contrasting professional profiles. We elicite...
