An extension to the chooser and inquiry framework motivated by a Japanese clause generator capable of expressing levels of politeness makes this facility available for revealing the distinctions necessary among interpersonal social meanings also. This paper shows why the previous inquiry framework was incapable of the kind of semantic control Japanese politeness requires and how the implemented extension achieves that control. An example is given of the generation of a sentence that is appropriately polite for its context of use and some implications for future work are suggested. 1 Introduction - inquiry semantics A crucial task in text generation is to be able to control linguistic resources so as to make what is generated conform to what is to be expressed. In the computational systemic-functional grammar SFG Nigel Mann 1985 Matthiessen 1985 Mann and Matthiessen 1985 this task is the responsibility of the grammar s inquiry semantics. Nigel follows general systemic-functional linguistics SFL practice in presenting grammar as a resource for expressing meanings meanings are realized by a network of interlocking options and particular grammatical forms are arrived at by making choices In this network. Generating appropriate text is then a problem of making the choices in such a way that the distinct needs of individual texts to be expressed are satisfied.
