COOL: A Chinese Object-Oriented Language for Knowledge Representation of Geometric Figures

Abstract

In order to provide a user-friendly interface for students to use a computational environment for learning programming in Chinese and learning elementary geometry, we have developed a Chinese Object-Oriented Language (COOL) for knowledge representation and a script language for describing geometric figures. COOL is used to define classes such as line segment and triangle and is similar in some aspects to other knowledge representation languages such as frames and semantic nets. A user can use the script language to draw geometric figures in a very simple, intuitive way. The script language is interpreted as Chinese Logo (CLogo) source code, whose execution will display the geometric figure in a CLogo drawing environment.
