Abstract :
This paper presents the architecture of a system for automatically assessing the answers of elementary algebra proving problems. The system parses the answer given by the student, which is written in Chinese, and constructs its corresponding formal proof in a theorem proving system. Then the correctness of the formal proof, which is the semantic of the original answer, can be verified in the theorem proving system automatically.
