The purpose of the Japanese interface is to enable a Japanese-speaking user to make choices in the system network in order to generate English sentences. Typically, the Japanese user would have some knowledge of English, but would have great difficulty in using complexes of auxiliary and modal verbs correctly.
Because the generation is controlled by the systemic mini-grammar, the inquiry semantics approach guarantees that a coherent and complete set of choices will always be made, and the realization rules guarantee that the generated sentences using these choices will always be well-formed. The problem is how to present the functional choices for English to the Japanese user.
