Thirty-two users had to solve simple statistics problems using an unfamiliar statistical package. Users received help on how to use the statistical package by typing utterances to what they believed was a computerized adviser. The observed limited set of users grammatical and ungrammatical forms demonstrates the sufficiency of a very restricted grammar of English for a natural language interface to an advisory system. The users language shares many features of spoken face-to-face language or of language generated under realtime production constraints . very simple forms of utterances . Yet users also appeared to believe that the natural language interface could not handle fragmentary or informal language and users planned or edited their language to be more like formal written language . very infrequent fragments and phatics . Finally users also appeared to believe in poor shared context between users and computerized advisers and referred to objects and events using complex nominals instead of faster-to-type pronouns. INTRODUCTION It has been argued that natural language interfaces with a very rich functionality are crucial to the effective use of advisory systems and that interfaces using formal languages menus or direct manipulation will not suffice Finin Joshi and Webber 1986 . Designing developing and debugging a rich natural language interface its parser grammar recovery strategies from unparsable input etc. are timeconsuming and labor-intensive. .
