    Abstract
    A conception of the nature and structure of user questions is presented. A classification of questions, in which questions are classified on the basis of their conceptual presupposition, also id presented. Examples of user questions are provided along with an analysis of their structure. Rules for making a structural analysis of questions and for classifying questions are provided. The use of these devices should facilitate the processing of user questions and the performance of information systems
