Intelligent tutoring systems (ITS) are a new generation of computer systems for support and improvement of learning and teaching. The usual definition of an ITS characterizes it as a system based on some kind of knowledge which includes domain, teachers' and students' knowledge. In the paper we elaborate on the representation of knowledge in an intelligent authoring shell which is an ITS generator system Tutor-Expert System. Within TEx-Sys knowledge is represented through semantic networks with frames and production rules. Nodes are used for representation of domain knowledge objects, while links show relations among them. Besides, TEx-Sys supports properties and frames, as well as property inheritance and frames containing a conclusion-making mechanism.
