摘要

The present paper describes a self-tutoring system CG―EST (Conceptual Graphs Elearning Self-Tutoring system). The purpose of this system is to generate questions to the user from given text lessons, to process user answers and to check their correctness. CG―EST includes modules for: parsing and producing logical forms (LF); generating conceptual graphs (CG) based on LF; generating questions based on LF; defining the scope of correct answer using CG operations; matching the user's and correct answers. This approach assists the automatic eLearn-ing systems being developed for various domains with some requirements: all sentences in the lessons have to use Controlled English (CE); to each lesson a simple concept type hierarchy and a synonyms set have to be attached. However these restrictions are useful for semantic interpretation of Natural Language (NL) texts. Thus CG―EST presents a solution for self-service eLearning that is ideal for training in a specific field.
