Impertinent Question-Answering Systems
Laurent Siklóssy · 1978
A Question-Answering System (QAS) is impertinent if it tells a user something the user did not ask! Since a user rarely understands the full implications of a data base, especially a large one, his question is limited by his knowledge of the data base. Sometimes, a question similar to the one he originally asked could better satisfy his goals, but he did not ask it because he had no reason to do so. Hence, impertinence is a necessary feature of sophisticated QAS.
