Abstract
The goal of the Atlas project is to increase the opportunities for students to construct their own knowledge by conversing (in typed form) with a natural language-based ITS. In this paper we describe two components of Atlas—APE, the integrated planning and execution system at the heart of Atlas, and CARMEL, the natural language understanding component. These components have been designed as domain-independent rule-based software, with the goal of making them both extensible and reusable. We illustrate the use of CARMEL and APE by describing Atlas-Andes, a prototype ITS built with Atlas using the Andes physics tutor as the host.
This research was supported by NSF grant number 9720359 to CIRCLE, the Center for Interdisciplinary Research on Constructive Learning Environments at the University of Pittsburgh and Carnegie-Mellon University.
