A User Modelling Approach for Computer-Based Critiquing
Abstract
Theoretical studies and implementations of computer-based critiquing systems indicate that it is desirable to enhance that approach to better support human-computer collaborative effort. A user model will enable these systems to individualize explanations of their advice to provide better support for cooperative problem solving and enhance user learning. User modelling research in advice-giving dialog and intelligent educational systems was studied together with theoretical analyses of the limitations of human-computer interaction, and empirical observations of human-to-human collaborative effort. A framework for a user modelling component fo a critiquing system was developed and implemented in a critic for LISP programs. The user models developed by the system were compared to self-assessment questionnaires completed by subjects learning the LISP language. The analyses indicated a favorable correlation and potential improvements to the framework. The user model is based on the conceptual domain model required for explanations; its semantic structure allows the system to implicitly enrich the user model contents. The significance of this thesis is a framework for a user modelling component that can be used for a more general class of cooperative knowledge-based systems.
