Abstract

En 中文

This paper describes a cooperative interface that, using suitable user models, alters the processing of the user's queries to include additional information that will block faulty inferences. In a sense, the interface actively teaches the user facts about the database that he did not explicitly asked for. User interaction with the database then becomes a learning and discovery process guided by the queries he poses to the interface. The paper also introduces a semantics for user models that captures, with the help of default logic, the nonmonotonic behavior users normally exhibit. Finally, the paper contains results showing that the cooperative interface generates enough additional information to block all faulty inferences.
