This paper presents a critical discussion of the vari- ous approaches that have been used in the evaluation of Natural Language systems. We conclude that pre- vious approaches have neglected to evaluate systems in the context of their use, e.g. solving a task requir- ing data retrieval. This raises questions about the validity of such approaches. In the second half of the paper, we report a laboratory study using the Wizard of Oz technique to identify NL requirements for carry- ing out this task. We evaluate the demands that task dialogues collected using this technique, place upon a prototype Natural Language system. We identify three important requirements which arose from the task that we gave our subjects: operators specific to the task of database access, complex contextual refer- enc...
